Abstract:
AbstractA novel Schiff base was synthesized and characterized by spectroscopic and theoretical methods. A potentially active agent 4-(2-hydroxy-5-methylphenylimino)naphthalen-1(4H)-one (PINQ) was designed and synthesized. The synthesis was carried out by a condensation reaction of 1-4-naphthoquinone and 2-amino-4-methyl phenol. The spectral and structural properties of the PINQ molecule were investigated by elemental analysis, 1H- and 13C-NMR, FT-IR and Uv-vis spectroscopies. The energetic, atomic, electronic, molecular, vibrational and magnetic data were theoretically obtained using density functional theory (DFT) at B3LYP level with 6-311++G(d,p) basis set. Chemical shifts were calculated using gauge-invariant atomic orbital (GIAO) method. UV-vis spectrum for the title compound was also obtained by time-dependent density functional theory (TD-DFT). The theoretical and experimental results were compared and interpreted. The theoretical data obtained from 1H- and 13C-NMR, FT-IR and Uv-vis spectroscopies were quite compatible with experimental ones.

New class of clamshell-type lanthanide (Ce(IV), La(III) and Eu(III)) diphthalocyaninates bearing 24-crown-8 linking fragment are synthesized and characterized by means of NMR, UV-vis spectroscopies and MALDI-TOF mass spectrometry. A strong solvatochromism of the complexes, allowing switching the wide-range panchromatic absorption in polar solvents, is demonstrated by means of UV-vis and NMR spectroscopies and attributed to solvent-induced changing of sandwich conformations. The photodegradation of the obtained complexes was also investigated.

Abstract:
L'objectif de ce travail porte sur l'amelioration des conditions de preparation de catalyseurs au nickel supporte sur silice, afin d'obtenir soit des phases silicate supportees d'un type donne, soit des ions ni(ii) isoles. La realisation de cet objectif passait par (i) la maitrise des parametres intervenant a l'interface liquide-solide lors du depot des ions metalliques et (ii) la comprehension des phenomenes produits lors de l'activation thermique. La methode d'echange cationique competitif en milieu ammoniacal ne permet pas d'obtenir des ions ni(ii) isoles mais aboutit a la formation de phyllosilicates (silicates lamellaires). En utilisant cette methode, nous avons determine les conditions d'obtention de phases de type talc ou serpentine, en jouant sur le ph, la concentration des ions competiteurs et la surface specifique du support. Les resultats ont ete interpretes en termes de competition entre la dissolution de la silice et la precipitation de la phase silicate. Nous avons etudie l'influence de 4 methodes de depot du nickel sur le comportement des materiaux au cours du traitement thermique, afin d'augmenter la proportion d'ions ni(ii) isoles et correlativement celle d'ions ni(i) apres reduction photochimique. En utilisant les spectroscopies xas et uv-vis-pir, nous avons caracterise les especes ioniques (ni(ii), ni(i)) de surface. L'utilisation de ligands chelatants permet d'obtenir une excellente dispersion des ions ni(ii) (75%). Le taux de reduction en ions ni(i) augmente egalement et atteint 40% pour cette methode de depot. Cependant, l'activite de ces catalyseurs en dimerisation du propylene n'est pas correlee au nombre de sites ni(i), revelant ainsi la complexite du probleme par rapport aux hypotheses anterieures

Full text
Abstract:
Ce travail de thèse est centré sur l'étude expérimentale de deux types de transformations photo-induites observées dans différents complexes métalliques (Fe, Ru, ...) à ligand nitrosyle: (i) la photo-isomérisation au cours de laquelle le ligand NO passe d'un état lié par l'azote (M-NO, état stable GS) à un état lié par l'oxygène (M-ON, état métastable MSI). C'est un processus réversible et un second état métastable, 'side-on' MSII est observable au cours du processus inverse, MSI --> 'side-on' MSII --> GS; (ii) la libération photo-induite du radical NO°. La photo-isomérisation a été étudiée dans le système [Ru(py)_4Cl(NO)](PF_6)_2.1/2H_2O (sur monocristal) par la diffraction des RX, l'absorption visible statique et l'absorption UV-Vis résolue en temps. Nous avons pu mettre en évidence un processus d'absorption de photons (473 nm) en deux étapes, suivre la dynamique des transformations directes et inverses par l'évolution des paramètres de maille et des l'absorption optique visible, caractériser structuralement l'état 'side-on' MSII. La nature de l'état intermédiaire, MSII, lors du processus direct semble être différente de l'état 'side-on' mais la très faible population de cet intermédiaire n'a pas permis de trancher définitivement. Le rôle de la molécule d'eau dans la maille du complexe [Ru(py)_4Cl(NO)](PF_6)_2.1/2H_2O a été testé par diffraction des RX sur les échantillons hydratées, déshydratées et réhydratées. L'effet de déshydratation sur l'évolution des paramètres de maille et sur la génération d'espèces MSII au cours de la photo-commutation inverse, MSI --> MSII --> GS, est présenté. La libération photo-induite du radical NO° a été étudiée dans une solution d'acétonitrile du complexe trans-(Cl,Cl)[Ru^{II}(FT)Cl_2(NO)]PF_6 par spectroscopies d'absorption UV-Vis et Mi-IR, statiques et résolues en temps. En observant la dynamique ultra-rapide de la photo-transformation, nous avons mis en évidence un processus d'absorption de photons (406 nm) en deux étapes. La nature de l'état intermédiaire est discuté par rapport à de récents calculs théoriques et au processus de photo-isomérisation
This Ph. D. thesis is focused on the experimental study of two photo-induced processes observed in various [ML_5NO] complexes, where M=Fe, Ru, ..., L=CN, Cl, ... : (i) photo-isomerization, where the system goes from N-bound state (M-NO, stable GS state) to O-bound state (M-ON, metastable MSI state) and a second metastable state, 'side-on' MSII is observed during the inverse photo-transformation, MSI --> 'side-on' MSII --> GS; (ii) photo-induced release of NO° radical. The photo-isomerization is investigated in single crystals of [Ru(py)_4Cl(NO)](PF_6)_2.1/2H_2O compound by means of X-Ray diffraction, steady state visible and time-resolved UV-visible absorption spectroscopies. During these experiments we observed the evidence of a two-step photon absorption process (473 nm), we followed the dynamics of direct and inverse photo-switching by the evolution of lattice parameters and absorption in the visible range and we caracterised the structure of 'side-on' MSII state. The nature of MSII in the direct photo-switching, GS --> MSI, seems to be different from the 'side-on' configuration, however, we do not have a direct access to this state due to its low population. The role of water molecule in the unit cell of [Ru(py)_4Cl(NO)](PF_6)_2.1/2H_2O complex was tested by X-Ray diffraction studies on hydrated, dehydrated and rehydrated samples. The effect of sample dehydration on the unit cell parameters evolution and MSII species generation during the MSI --> MSII --> GS inverse photo-switching is presented. The photo-induced NO° release in trans-(Cl,Cl)[Ru^{II}(FT)Cl_2(NO)]PF_6 system in acetonitrile solution is studied by the UV-visible and mid-IR absorption spectroscopies, both steady state and time-resolved. By observing the ultra-fast dynamics of photo-transformation we evidenced a two-step photon absorption process (406 nm). The nature of intermediate state is discussed within the recent theoretical calculations and the photo-isomerization process

Abstract:

In this report a model analysis is presented for three different nanostructured layers: silicon nanotips (SiNTs), gold nanosandwiches and Split Ring Resonators (SRR). The last two materials are metamaterials and both may show a negative refraction index. Experimental data are obtained for every sample using a variable angle spectroscopic ellipsometer. For the gold nanosandwiches, also an infrared ellipsometric measurement is done. For complex layers like these, advanced modeling is necessary. A recently developed analysis program including options for both anisotropic permittivity and permeability is used. A realistic model is presented in this report for the gold nanosandwiches, which also includes the magnetic activity in the layer itself. The results for the nanosandwiches are reasonable, and a magnetic oscillation is found in the horizontal plane at around 260 nm although it was not expected to have a resonance that far in the UV-range. For the SiNTs and the SRR it was not possible to create an acceptable model.

Full text
Abstract:
Nous créons des films minces smectiques de défauts topologiques linéaires sur substrats de polymère grâce au savoir faire acquis sur substrats cristallins. Le transfert de ce système sur polymère permet d'étudier l'influence du substrat sur la structure du film, et de mener un nouveau type d'étude par diffraction des rayons X en adoptant deux configurations couplées en réflexion et en transmission. D'autre part, en mélangeant des nanoparticules (NPs) à ces films, on transmet leur anisotropie aux auto-assemblages NPs d'or pour obtenir des propriétés optiques définies et activables par variation de la polarisation de la lumière. Dans le cas de films hybrides faiblement concentrés, nous créons des chaînes de NPs individuelles piégées par les dislocations smectiques, sur plusieurs dizaines de microns. En fonction de la concentration, les NPs peuvent être isolées ou en condition de couplage électromagnétique, permettant d'obtenir une anisotropie de la résonance de plasmon jusqu'à 40 nm. A plus grande concentration, le réseau linéaire de NPs se transforme en réseau bidimensionnel, toujours anisotrope, dont une direction dense est imposée le long des défauts. Pour le film smectique pur, un modèle avec un joint de grain tournant est retrouvé et interprété comme minimisant la présence de dislocations. Nous identifions deux sites de dislocations capables de piéger les nanoparticules : le premier site, préférentiel, piège les NPs dans un environnement ordonné situé près du substrat ; le second est en haut du joint de grain tournant plus proche de l'interface avec l'air, il mobilise une assemblée de dislocations reconstruites en fonction de la concentration en NPs. Finalement, cette auto-organisation dirigée de nanoparticules, ouvre la voie pour l' étude de systèmes hybrides de particules plus grandes ou de formes anisotropes pour exalter les effets d'anisotropie de l'auto-assemblage.

Abstract:
In this project Vanadium complex -Vanadium (IV) - flavone was synthesized using vanadium (IV) acetylacetonate (VO(acac)2) complex and 3-hydroxy-6-methyl flavone ligand. The complex stability was checked using FTIR and UV-vis spectroscopies. Peackes around 990 cm-1 conforms the formation of (V=O) in the complex, as well as (V-O) around 790 cm-1. In UV-Vis spectrum peak around 400-450 nm was noticed, which conforms the formation of the vanadium complex that correspond to the ligand to metal charge transfer (LMCT) transition. The radical scavenging abilities of vanadium complex were investigated using DPPH. The anti-oxidant activity using (BHA) as a standard reference, the complex synthesized displayed strong DPPH antioxidant radical scavenging activity compared to VO(acac)2 and BHA, with IC50 value of (105, 95 and 96) mM respectively. The absorbance in which the reducing power occurred were found to be (0.397, 0.825 and 0.228) for the complex, VO(acac)2 and BHA.

Full text
Abstract:
To improve the efficiency of water splitting by photocatalysis, a semiconductor heterojunction made of titanium dioxide (TiO2) and strontium titanate (SrTiO3) is constructed to promote the separation of photo-induced electron and hole (e− /h+) pairs. The photocatalytic behaviors of the TiO2-SrTiO3 composite film and nanostructure fabricated by the sol-gel and hydrothermal methods are studied. UV-visible and ultraviolet photoelectron spectroscopies (UV-Vis & UPS) are adopted to identify the band structure of the TiO2-SrTiO3 heterojunction. For the composite film system, an approximately 0.5 eV band shift at the heterojunction improves the separation of photoinduced e−/h+ pairs. The photocurrent density of the composite film is about 2–3 times larger than that of the TiO2 or SrTiO3 film alone. For the composite nanostructure system, it is composed of an array of TiO2 nanotubes coated with SrTiO3 nanoparticles. An approximately 0.2 eV band shift at the heterojunction is determined for the composite nanostructure. It is found that the size of the SrTiO3 nanoparticles, which can be controlled by the hydrothermal temperature and time, is a key factor in influencing the photocurrent density of the TiO2-SrTiO3 composite nanostructure.

Abstract:
Considerable interest exists in the application of single wall carbon nanotubes (SWNTs) to proton exchange membrane fuel cells (PEMFCs). Proposed applications include use as anode materials in both hydrogen and direct methanol fuel cells, solid polymer electrolyte additives, active cathode materials, and bipolar plate interconnects. SWNTs have extremely high electrical conductivity and catalytic surface areas which make them potentially outstanding active materials for PEMFC electrodes. Additionally the enhanced mechanical properties may play a roll in developing new fuel cell designs such as thin-film microelectronic fuel cells. In a previous study SWNTs were combined with commercially obtained E-TEK Vulcan XC-72 and Nafion® to produce composite cathode membranes. The addition of nanotubes resulted in enhanced fuel cell performance over an equivalent weight percent doping of E-TEK alone. This increased performance was achieved with a 50% reduction in the quantity of platinum present in the cathode. In the present study we investigate fuel cell performance when both the anode and cathode membranes contain graphite, platinum and SWNTs. The SWNTs were characterized by use of thermogravimetric analysis, Raman and UV/VIS/NIR spectroscopes as well as high resolution field emission scanning electron microscopy. Fuel cell performance was determined by comparison of the IV characteristics.
