Abstract:
A one-dimensional (1D) coordination polymer [Cu2(bpba)(CH3COO)4] (1) and a two-dimensional (2D) coordination polymer [Cu(bpba)2(H2O)(NO3)](NO3)∙2H2O∙MeOH (2) were synthesized by the reaction between Cu(CH3COO)2∙H2O/Cu(NO3)2∙3H2O and bis(4-pyridyl)benzylamine (bpba). The Cu(II) ions of 1 and 2 have distorted-square pyramidal coordination with a paddle-wheel structure and an octahedral geometry, respectively. By coordinating the Cu(II) ions and bpba ligands, 1 and 2 formed zigzag 1D and puckered 2D coordination polymers, respectively. Polymer 1 exhibits strong emissions at 355 and 466 nm, whereas polymer 2 exhibits strong emissions only at 464 nm. The emissions are strongly dependent on the geometry of the Cu(II) ions linked by the bpba and anionic ligands. Polymer 1 exhibits a very strong antiferromagnetic interaction within the paddle-wheel dimer, whereas polymer 2 exhibits a very weak antiferromagnetic interaction through the bpba linkers and/or space.

Abstract:
The present work reports the synthesis of new N4-donor compounds carrying p-xylyl spacers in their structure. Different Schiff base aliphatic N-donors were obtained synthetically and subsequently evaluated for their ability to interact with two models of nucleic acids: calf-thymus DNA (CT-DNA) and the RNA from yeast Saccharomyces cerevisiae (herein simply indicated as RNA). In more detail, by condensing p-xylylenediamine and a series of aldehydes, we obtained the following Schiff base ligands: 2-thiazolecarboxaldehyde (L1), pyridine-2-carboxaldehyde (L2), 5-methylisoxazole-3-carboxaldehyde (L3), 1-methyl-2-imidazolecarboxaldehyde (L4), and quinoline-2-carboxaldehyde (L5). The structural characterisation of the ligands L1-L5 (X-ray, 1H NMR, 13C NMR, elemental analysis) and of the coordination polymers {[CuL1]PF6}n (herein referred to as Polymer1) and {[AgL1]BF4}n, (herein referred to as Polymer2, X-ray, 1H NMR, ESI-MS) is herein described in detail. The single crystal X-ray structures of complexes Polymer1 and Polymer2 were also investigated, leading to the description of one-dimensional coordination polymers. The spectroscopic and in silico evaluation of the most promising compounds as DNA and RNA binders, as well as the study of the influence of the 1D supramolecular polymers Polymer1 and Polymer2 on the proliferation of Escherichia coli bacteria, were performed in view of their nucleic acid-modulating and antimicrobial applications. Spectroscopic measurements (UV–Vis) combined with molecular docking calculations suggest that the thiazolecarboxaldehyde derivative L1 is able to bind CT-DNA with a mechanism different from intercalation involving the thiazole ring in the molecular recognition and shows a binding affinity with DNA higher than RNA. Finally, Polymer2 was shown to slow down the proliferation of bacteria much more effectively than the free Ag(I) salt.

Abstract:
Various kinds of monocrystalline coordination polymers are available thanks to the rapid development of related synthetic strategies. The intrinsic properties of coordination polymers have been carefully investigated on the basis of the available monocrystalline samples. Regarding the great potential of coordination polymers in various fields, it becomes important to tailor the properties of coordination polymers to meet practical requirements, which sometimes cannot be achieved through molecular/crystal engineering. Nanoarchitectonics offer unique opportunities to manipulate the properties of materials through integration of the monocrystalline building blocks with other components. Recently, nanoarchitectonics has started to play a significant role in the field of coordination polymers. In this short review, we summarize recent advances in nanoarchitectures based on monocrystalline coordination polymers that are formed through confined assembly. We first discuss the crystallization of coordination polymer single crystals inside confined liquid networks or on substrates through assembly of nodes and ligands. Then, we discuss assembly of preformed coordination polymer single crystals inside confined liquid networks or on substrates. In each part, we discuss the properties of the coordination polymer single crystals as well as their performance in energy, environmental, and biomedical applications.

Abstract:
In this study, two new coordination polymers of Cu(II) and Cd(II) ions with pyrazine-2,3-dicarboxylic acid and 1-vinylimidazole were synthesized. The structures of these coordination polymers were characterized with elemental analysis, infrared spectroscopy, thermal analysis, powder X-ray diffraction, and magnetic susceptibility techniques. According to the results of the thermal analysis, the coordination polymers that contained water molecules decomposed below 100 °C, and the final products for both coordination polymers were the related metal oxides in an oxygen atmosphere. Powder X-ray diffraction analysis revealed that the coordination polymers were in the crystalline form. The hydrogen storage capacities and surface areas of the coordination polymers were also determined. The highest hydrogen storage capacities were measured as 296 ml/g for the Cu(II) coordination polymer and 330 ml/g for the Cd(II) coordination polymer at approximately 75 bar and 75 K.

Abstract:
Coordination polymers with a new rigid ligand 1,3-bis(1,2,4-triazol-1-yl)adamantane (L) were prepared by its reaction with cadmium(II) or silver(I) nitrates. Crystal structure of the coordination polymers was determined using single-crystal X-ray diffraction analysis. Silver formed two-dimensional coordination polymer [Ag(L)NO3]n, in which metal ions are linked by 1,3-bis(1,2,4-triazol-1-yl)adamantane ligands, coordinated by nitrogen atoms at positions 2 and 4 of 1,2,4-triazole rings. Layers of the coordination polymer consist of rare 18- and 30-membered {Ag2L2} and {Ag4L4} metallocycles. Cadmium(II) nitrate formed two kinds of one-dimensional coordination polymers depending on the metal-to-ligand ratio used in the synthesis. Coordination polymer [Cd(L)2(NO3)2]n was obtained in case of a 1:2 M:L ratio, while for M:L = 2:1 product {[Cd(L)(NO3)2(CH3OH)]·0.5CH3OH}n was isolated. All coordination polymers demonstrated ligand-centered emission near 450 nm upon excitation at 370 nm.

{[Ni2C6H2(COO)4(H2O)4]·H2O2,5}n binuclear coordination compound with supramolecular structure has been synthesized. The composition and chemical structure of the coordination compound have been determined by the elemental, X-ray, IR spectroscopic and differential thermal analyzes. The unit cell parameters have been determined by identifying the diffraction pattern and the inferred schematic structure of the two-dimensional polymer layer of the coordination polymer, which is the building block for all the studied coordination compounds from this series, has been given. The layers are connected with each other and shifted relative to each other depending on the direction and strength of the hydrogen bonds; and this leads to a change in the parameters of the unit cells. Thus, two-dimensional polymer layers (2D) are transformed into a 3D supramolecular structure

Abstract An interesting 3-D supramolecular architecture has been constructed through O-H・ ・ ・O and S・ ・ ・S weak interactions based on a neutral 1-D coordination polymer, [Cd(pyta)2(H2O)]n (pyta = pyridylthiocarboxylate), by self-assembly of the Cd2+ion and Hpyta ligand. This supramolecular approach is achieved in combination of coordinative bonds, O-H・ ・ ・O and S・ ・ ・S interactions. The tetragonal unit of 1-D coordination polymers forms a 1-D channel structure with a dimension of 5.35×6.86 Å2in the solid state, leading to the formation of zeolite-like materials. In combination with the zeolitelike nature of the title compound as well as its luminescence behavior, it is expected to find useful applications in luminescence sensing for VOCs (volatile organic compounds).

Abstract:
Using a solvothermal method, we have synthesized two coordination polymers of Cu(II). One is a 1D polymer {[Cu(bpy)(NDC)(H 2 O)].2H 2 O} n (1, 1D) formed with 1,8-naphthalene dicarboxylic acid (H 2 NDC) and 2,2′ -bipyridine (bpy) as an auxiliary ligand, while the other is a 2D polymer {[Cu 3 (TMA)(Imd) 3 ].5H 2 O.2DMF} n (2, 2D) formed with trimellitic acid (H 3TMA) and imidazole (Imd) as an auxiliary ligand. Both coordination polymers 1 and 2 were formed through an in situ hydrolytic ring opening reaction of 1,8-naphthalic anhydride and trimelitic anhydride with bipyridine and imidazole ligands, respectively. The asymmetric unit of polymer 1 contains asymmetric η 1 binding mode (one of the carboxylate) linking distorted square-pyramidal [Cu(NDC)(bpy)(H 2 O)] 2+ coordination units. The syn-syn-η 1 :η 1 linear polymer conformation exist in the 1D coordination polymer with adjacent Cu…Cu distance is 6.849Å. A chain of cyclic tetrameric water clusters is present between the stacked layers of the 3D supramolecular structure. The formation of the 3D supramolecular structure is guided by various weak interactions such as OH…O, CH…O, CH…π and π…π interactions. The coordination polymers 2 forms 3D supramolecular architecture guided by various weak interactions such as OH…O, CH…O and NH…O interactions. The crystal structures of both coordination polymers have been determined using single crystal X-ray diffraction and their structural features are described.

Full text
Abstract:
Les alginates, polysaccharides extraits des algues brunes, sont des copolymères à blocs linéaires formés d'unités mannuronates (M) et guluronates (G). Leur structure dépend de la source naturelle. La complexation de cations divalents ou trivalents (sauf Mg2+) par les fonctions carboxylates conduit à la formation d'un hydrogel. Pour approfondir l'étude de la formation des gels ionotropiques d'alginate, des hydrogels et des aérogels séchés en conditions supercritiques ont été caractérisés à plusieurs échelles par différentes techniques. L'analyse orbitalaire ab initio de petits complexes a montré la formation de liaisons covalentes fortes avec les métaux de transition alors que les alcalino-terreux ne mettent en jeu que des interactions électrostatiques. Selon le rapport M/G et la nature des cations, différents régimes structuraux ont pu être identifiés par des mesures SAXS (~10-200Å) : des gels fibrillaires ou formés d'agglomérats interconnectés. Les propriétés mécaniques des hydrogels et les surfaces spécifiques des aérogels correspondants sont directement reliées à ces morphologies. La présence simultanée de plusieurs métaux dans les gels peut induire des effets coopératifs dans la formation mais aussi dans les propriétés des matériaux. De nouvelles méthodes ont été mises au point pour contrôler la synthèse de gels hétéro-cationiques, en considérant les effets d'affinité.Sur la base de cette étude, des synthèses originales de matériaux fonctionnels nano-structurés ont été développées. Certains ont été construits directement dans le réseau d'alginate en exploitant les cations de gélification ; d'autres ont nécessité le sacrifice de la matrice pour former des oxydes simples ou mixtes nanocristallins
Alginates, polysaccharides produced by brown algae, are linear block-copolymers formed by mannuronate (M) and guluronate (G) units. Their structure depends on the natural source. The coordination of divalent or trivalent cations (except Mg2+) with the carboxylate functions leads to the formation of a hydrogel. In order to get some insight in ionotropic alginate gel formation, hydrogels and supercritical dried aerogels were analysed through various characterizations at different scales. The ab initio molecular orbital analysis on small complexes revealed strong coordination-covalent bonds in the transition metal complexes, whereas only ionic interaction occurs between the alkaline-earth cations and the carboxylates. Depending on the M/G ratio and the nature of the cation, different structural regimes were identified by SAXS analysis (~10-200Å) : well-defined fibrillar gels or gels with multiple junction nature. The mechanical properties of the hydrogels and surface areas of the resulting aerogels are directly related to these morphologies. The concomitant presence of different metals in the gel can bring cooperative effect for the formation but also for the properties of the materials. New methods to control the synthesis of hetero-cationic gels were implemented, taking into account the affinity effects. On the basis of this study, we developed new nanostructured functional materials synthesis. Some were built directly in the alginate network using the gelling cations. Others needed to sacrifice the matrix to form nanocrystalline single or mixed oxides

Abstract:
Les polymères de coordination (PC) présentent un intérêt tant fondamental qu'appliqué de par leur structure et composition modulables ouvrant de nouvelles perspectives au niveau des propriétés chimiques (catalyse, conversion matériaux mous-durs…) et physiques (magnétisme, optique…). L'objectif principal de ces études consiste à vérifier le transfert de la structure, méso-structure et composition du PC vers la céramique obtenue par traitement thermique. Dans ce contexte, ce manuscrit décrit des études sur la conversion de polymères de coordination obtenus à partir d'un auto-assemblage entre des métaux 4f, 5f et de la 2,5-dihydroxy-1,4-benzoquinone (DHBQ). Dans un premier temps, des méthodes de synthèses, aqueuse et anhydre en atmosphère contrôlée, ont été mises au point. Ainsi, plusieurs types de PC ont été obtenus (4f, 4f-4f, 4f-5f), les composés mixtes formant des solutions solides. Après caractérisation de ces composés, leur comportement sous traitement thermique a été étudié. Les principaux résultats montrent que les précurseurs à base de DHBQ obtenus par voie aqueuse possèdent une méso-structure micrométrique, formée par l'assemblage de sous-unités monocristallines possédant la même structure cristallographique quelle que soit la morphologie observée. L'étude de l'assemblage de cette méso-structure a permis de contrôler la morphologie du grain élémentaire (cylindre, cube, disque…) avec une très bonne distribution en taille. La mise en œuvre de systèmes anhydres en atmosphère contrôlée a permis d'accéder à une plus large gamme de paramètres micro-structuraux (surface spécifique, porosité…). Pour l'ensemble des composés de type PC, la conversion thermique en céramique n'a pratiquement pas altéré la morphologie des matériaux. Les aspects microstructuraux ont pu être contrôlés via la méthode de synthèse
Coordination polymers (CP) are of great academic and industrial interest due to flexible structure and composition and offer prospects for original chemical (catalysis, soft-hard materials conversion…) and physical properties (magnetism, optics…). The major interest of these studies is to check the transfer of the structure, meso-structure and composition from the CP to the ceramic via a thermal treatment. In this context, this thesis describes studies on conversion of coordination polymers obtained by self-assembly of 4f and 5f metal ions with 2,5-dihydroxy-1,4-benzoquinone (DHBQ). Aqueous and anhydrous synthetic ways were developed, which yielded different kinds of CPs (4f, 4f-4f, 4f-5f) ; solid solutions were obtained with the mixed compounds. The products were characterized and their behaviour under thermal treatment was studied. The main results show that the DHBQ-based precursors obtained by aqueous way have a micrometric meso-structure, formed by the assembly of micro-crystalline subunits which all posses the same crystallographic structure. The study of the assembly of the meso-structure allowed controlling the morphology of the elementary grain (cylinder, cube, disk ...) with very good size distribution. The implementation of anhydrous systems in a controlled atmosphere allowed yielded a wider range of micro-structural parameters (surface area, porosity ...). For all CP-type compounds, the thermal conversion to ceramic has barely altered the morphology of the materials. The microstructural aspects could be controlled via the method of synthesis

Nous avons mis en place un dispositif de microscopie par génération de somme de fréquences optiques pour étudier les milieux isotropes chiraux. Ce dispositif a tout d'abord été validé en utilisant la molécule chirale de bi-2-naphtol en solution liquide et en milieu sol-gel. Nous avons établi les conditions expérimentales permettant de limiter les phénomènes de blanchiment par absorption biphotonique du chromophore. Nous avons ensuite entrepris une étude des polymères de coordination chiraux élaborés à partir de l'auto-assemblage de ligands organiques chiraux et d'ions métalliques en solution. Nous avons mesuré un signal SFG chiral apparaissant lors du séchage de films de polymères et de complexes de coordination chiraux. Nous démontrons ainsi que la technique de microscopie SFG spécifique des milieux isotropes chiraux permet de détecter le processus de coordination des polymères de coordination chiraux en phase condensée et de suivre l'établissement de la phase solide
We have built a set-up to perform sum frequency generation (SFG) microscopy in order to study isotropic chiral media. This set-up was first validated with molecules of bi-2-naphthol in liquid solution and sol-gel matrices. We have established the experimental conditions to limit the bleaching phenomena of the chromophore by two-photon absorption. Next, we have conducted a study of chiral coordination polymers produced through the self-assembly of chiral organic ligands and metal ions in solutions. We have measured a chiral SFG signal developing while films of chiral coordination polymers and complexes are drying. Thus we show that SFG microscopy specific to isotropic chiral media makes it possible to detect the coordination process of chiral coordination polymers in the condensed phase and monitor the establishment of the solid phase

Full text
Abstract:
Cette thèse est consacrée à la synthèse de polymères de coordination bidimensionnels (2D) et tridimensionnels (3D) magnétiques à base du ligand organique pyrazine et de cations de métaux 3d. De tels matériaux sont généralement paramagnétiques, ou bien magnétiquement ordonnés à des températures très inférieures à celle de l’azote liquide. Dans cette thèse, les propriétés redox du ligand pyrazine ont été utilisées afin de permettre l’obtention d’ordre magnétique au-delà de cette température (77 K). Le chapitre I présente les notions de magnétisme utiles à la lecture de cette thèse. Une étude bibliographique est ensuite proposée décrivant les polymères de coordination magnétiques à haute température critique, l’obtention de radicaux par réduction post-synthétique, les propriétés des matériaux multifonctionnels magnétiques et poreux, et les polymères de coordination 3D à base de pyrazine connus sous le nom de SIFSIX-3-M. Les chapitres II et III sont consacrés à la réduction post-synthétique des composés 2D Co(pyz)2Cl2 et Fe(pyz)2Cl2, qui a mené à la formation de pyrazine radicalaire, et à l’obtention de phases ferri-magnétiques à haute température. Le chapitre IV évoque la synthèse de nouveaux réseaux 3D, dont certains sont antiferromagnétiques à basse température. La stratégie de réduction post-synthétique a été testée sur l’un d’eux pour tenter d’augmenter la température critique à laquelle le composé est magnétiquement ordonné
This thesis is devoted to the synthesis of two-dimensional (2D) and three-dimensional (3D) pyrazine-based magnetic coordination polymers with 3d metal cations. Such compounds are often paramagnetic or magnetically ordered at low temperature (below 77 K, the temperature of liquid nitrogen). In order to achieve magnetic ordering at high temperature (> 77 K), the redox-active bridging ligand pyrazine has been used. In the first chapter, fundamentals of magnetism useful for the reading of the thesis are introduced. After that, a bibliographic study about magnetic coordination polymers with high critical temperature, creation of organic radicals by post-synthetic reductions, properties of multifunctional porous magnetic materials, and 3D coordination polymers known as SIFSIXs is proposed. Chapters II and III are devoted to post-synthetic reduction of the 2D compounds Co(pyz)2Cl2 and Fe(pyz)2Cl2, leading to radical pyrazine and high temperature magnetic ordering. In chapter IV, three new 3D networks are described, among two showing antiferromagnetic phases at low temperature. Post-synthetic reduction has been tried on one of those to try to increase the critical temperature in which the compound is magnetically ordered

Abstract:
La conception de matériaux capables de piéger sélectivement le CO2 revêt un enjeu majeur dans le développement de procédé de capture post-combustion pour de nombreux secteurs industriels. Nos travaux visent l'élaboration de nouveaux polymères de coordination de type MOF (“Metal-Organic Framework”) préparés par auto-assemblage de briques moléculaires polycarboxyliques avec des métaux de transition qui constituent les noeuds du réseau tridimensionnel. Ces matériaux hybrides microporeux présentent des propriétés d’adsorption du CO2 importantes. Notre approche a consisté à synthétiser des polymères de coordination dans le but d'accroître la capacité et la sélectivité d'adsorption du CO2 vis-à-vis d'autres gaz comme CO, CH4, N2 et O2 grâce à des interactions physiques impliquant le moment quadripolaire élevé du CO2 et le potentiel électrostatique existant dans les pores du matériau. Dans ce mémoire sont décrites les synthèses des différentes briques moléculaires organiques constituées de polyamines et de polyazamacrocycles Nfonctionnalisées par des terminaisons benzocarboxylate. Des matériaux homo- et hétéro- bimétalliques présentant des structures cristallines originales ont été obtenus à partir de briques moléculaires triazamacrocycliques N-fonctionnalisées par des terminaisons acides carboxyliques et différents cations métalliques (Zn2+, Co2+, Cd2+ et Ni2+). Les études de ces polymères de coordination poreux ont révélé leur capacité d’adsorption importante du CO2 avec une sélectivité remarquable dans les conditions normales de température et de pression
The design of material able for CO2 capture is a major issue to achieve post-combustion capture process for many industries. Our work aims to develop new coordination polymer MOF (“Metal-Organic Framework”) prepared by self-assembling polycarboxylic linkers and transition metals. These microporous hybrids materials show important CO2 adsorption properties and are promising in the field of gas separation. The main topic of our work is to synthesise MOFs with high adsorption capacity and selectivity for CO2 over other gases (CO, CH4, N2 and O2). The gas-solid interactions are due to physical phenomena involving the high quadrupolar moment of CO2 and the electrostatic potential lying in the pore of the material. In this manuscript, the synthesis of various organic linkers incorporating N-functionalised polyamines and polyazamacrocycles with benzocarboxylate functions is described. Homo- and hetero- bimetallic materials with original tridimensional structure were obtained from a N-functionalised triazamacrocyclic linker and different metal cations (Zn2+, Co2+, Cd2+ and Ni2+). Studies of porous coordination polymers have shown high CO2 adsorption capacity with a remarkable selectivity in the ambient temperature and pressure conditions

Abstract:
L'objet majeur de cette étude est de contrôler la taille de nanoparticules de matériaux à transition de spin (TS), et d'étudier l'influence d'une réduction de taille sur les propriétés de commutation thermique. Plusieurs voies ont été explorées :
La première stratégie basée sur la synthèse d'oligomères puis l'assemblage en unités supérieures s'est révélée difficile due à un manque de réactivité. La deuxième approche a consisté à utiliser le confinement moléculaire au sein d'une nanogouttelette pour synthétiser des oligomères de coordination de quelques nanomètres, et mettre en place une véritable “ingénierie moléculaire” en microémulsion. La dernière partie de ce travail est consacrée à la synthèse de particules à TS d'une centaine de nanomètre en milieu micellaire inverse permettant la discussion de l'influence de la taille des particules sur le comportement coopératif.

Abstract:
Les polymères de coordination (PCs) à base de thiolates de métaux monétaires sont bien connus pour leurs propriétés luminescentes. Cependant, leurs structures sont sous-explorées. Dans cette thèse, nous présentons une étude pionnière visant la compréhension de la formation de la structure et de la corrélation ‘structure-propriétés’ des PCs homoleptiques neutres, [M(SR)]n, M = Cu(I), Ag(I), Au(I). Les composés avec les dérivés du thiophénolate étudiés dans ce travail, illustrent comment l'utilisation de certains ligands organiques fonctionnalisés conduit à la formation de réseaux 2D étendus ou de colonnes 1D par l'addition d'un encombrement stérique. De plus, la première étude structurelle comparative des PCs thiolées amorphes a été réalisée par analyse PDF. Les études photophysiques ont montré la diversité des propriétés luminescentes des PCs à base de thiolates de métaux monétaires. Des pics d'émission doubles ou multiples, un rendement quantique élevé, des émetteurs orange à proche infrarouge, des variations significatives de durée de vie en fonction de la température... toutes ces propriétés intrinsèques révèlent le potentiel élevé de ces composés pour diverses applications optiques
The coordination polymers (CPs) based on thiolates of coinage metals are well known for their luminescence properties. However, their structures stayed underexplored. In the thesis we present a pioneering study targeting the understanding of the structure formation and the ‘structure-properties’ correlation for neutral homoleptic CPs, [M(SR)]n, M = Cu(I), Ag(I), Au(I). The compounds with thiophenolate derivatives studied in the work, illustrate how the use of some functionalized organic ligands leads to the formation of extended 2D networks or 1D columns by addition of some steric hindrance. The first comparative structural study of amorphous thiolated CPs was performed by PDF analysis. The photophysical studies showed the diversity of luminescent properties of the CPs based on thiolates of coinage metals. Double or multiple emission peaks, high quantum yield of orange-toinfrared emitters, significant lifetime variation with temperature… all of these intrinsic properties reveal the high potential of these compounds for diverse optical applications

Abstract:
Ce mémoire est consacré à la synthèse, à la caractérisation et à l’étude des propriétés électrochimiques et photophysiques dans l’acétonitrile de complexes hétérobimétalliques comportant des unités photosensibles du type ruthénium(II)-tris-bipyridine reliées de manière covalente à une unité polypyridinique de fer (II) ou de cobalt (II), dans le but d’étudier les transferts d’électrons photoinduits dans de telles architectures. A l’aide de ligands bis-bipyridine, une série de complexes tétranucléaires formés d’une unité centrale FeII-tris-bipyridine reliée à trois unités RuII-tris-bipyridine par une chaîne alkyle de longueur variable, a été obtenue. L’examen de leurs propriétés photophysiques met en évidence un transfert d’énergie partiel, intramoléculaire, de l’état excité des unités, RuII*, vers l’unité centrale FeII. Ce transfert d’énergie est court-circuité en présence d’un accepteur d’électron irréversible externe par un processus de transfert d’électron, qui conduit à la formation d’espèces RuIII capables d’oxyder la sous-unité FeII. En utilisant un ligand hétéroditopique de type bipyridine–terpyridine, de nouveaux complexes trinucléaires comportant une unité centrale FeII ou CoII bis-terpyridine reliée à deux unités RuII-tris-bipyridine ont également été synthétisés. L’utilisation de ce type de ligand confère à ces complexes une structure plus linéaire. Dans le cas du complexe de FeII, le transfert d’énergie purement intramoléculaire peut également être court-circuité par un transfert d’électron en présence d’un accepteur irréversible conduisant à l’oxydation quantitative de la sous-unité FeII. Dans le cas du complexe de cobalt, le cycle photocatalytique envisagé implique la photogénération de l’espèce RuIII via un transfert d’électron entre RuII* et l’unité CoIII (préalablement générée par voie électrochimique) qui joue le rôle d’accepteur d’électron. Toutefois cette réaction catalytique est relativement lente car le donneur d’électron utilisé pour régénérer le RuII ne possède par une irréversibilité suffisante pour concurrencer la réaction retour, c’est-à-dire la réoxydation de CoII par RuIII. Enfin, l’étude de polymères de coordination électro-et photo-activables de RuII et FeII a été abordée. Ce type de polymères dérive des complexes trinucléaires de RuII et de FeII. Ils sont obtenus sous forme soluble grâce à l’utilisation de ligands hétéroditopique de type bipyridine-bis-terpyridine, dont la partie bipyridine est complexée par le RuII, tandis que l’ajout de Fe2+ permet la formation du polymère par auto-assemblage. Comme pour les complexes de FeII et de RuII de dimensions finies, l’oxydation photoinduite de l’unité FeII est possible bien que son efficacité dépende de la nature du pont entre la bipyridine et les terpyridines. De plus, ces polymères ont pu être adsorbés sous forme de films minces électroactifs à la surface d’une électrode (élaboration d’électrodes modifiées) par une technique simple d’électrodéposition
This work deals with the synthesis and physico-chemical study of heterobimetallic complexes bearing ruthenium(II)-tris-bipyridine units as photosensitizers covalently linked to a polypyridinic complex unit of iron (II) or cobalt (II), in order to investigate photoinduced electron transfer in such architectures. With bis-bipyridine type ligands, we synthesized a serie of tetranuclear complexes formed by a central complex unit FeII-tris-bipyridine, covalently linked to three RuII-tris-bipyridine subunits. Examination of their photophysical properties revealed a partial energy transfer between FeII subunit and excited state of RuII subunit, RuII*. This energy transfer can be easily short-circuited in presence of an external irreversible electron acceptor by an electron transfer process, leading to formation of RuIII species able to oxidize FeII subunit. By using a heteroditopic bipyridine-terpyridine type ligand, new trinuclear complexes bearing a central unit of FeII or CoII bis-terpyridine complex linked to two RuII-tris-bipyridine subunits were synthesized. This ligand confers to these architectures a more linear structure. In the case of the iron complex, purely intramolecular energy transfer can be short-circuited too, by electron transfer in presence of an external irreversible electron acceptor leading to the complete oxidation of FeII subunit. In the case of the cobalt complex, the photocatalytic cycle we considered implies formation of RuIII species via an electron transfer between RuII* and CoIII (previously electrogenerated) as electron acceptor. Nevertheless this reaction is fairly slow because the external electron donor used to regenerate RuII does not display a convenient irreversibility to prevent back electron transfer between CoII and RuIII. Finally, RuII and FeII electro- and photo-activable coordination polymers studies have been started. These types of polymers derive from the RuII and FeII trinuclear complex. They are obtained under soluble forms by the use of a heteroditopic bipyridine-bis-terpyridine type ligand, where the bipyridine part is complexed by RuII whereas addition of Fe2+ ions leads to the formation of polymers by a self-assembly process. Likewise RuII and FeII finished-dimension complex, photoinduced oxidation of FeII unit is possible even if its efficiency depends on the nature of the bridge between bipyridine and terpyridine units. Moreover, these polymers can be adsorbed as electroactive thin layers at the surface of an electrode (elaboration of modified electrodes) by a simple electrodeposition technique

Abstract:
The environmental concern with the use of synthetic polymers, above all, used in single-use packaging such as expanded polystyrene (EPS), is related to the use of non-renewable resources and, it is accentuated, with the prolonged decomposition time of this material in the environment. Cassava starch, a renewable and biodegradable polymer, offer a partial solution to the problem. Therefore, the objective of this work was to gather publications in natural polymers and to discuss the similarities and differences between these studies. The method of systematic literature review proposed by Conforto, Amaral and da Silva (2011) was used. The database used was the CAPES Journal Portal (Coordination for the Improvement of Higher Education Personnel).
