Polyoxometalates (POMs), which are inorganic metal oxide cluster anions with discrete structures, have been extensively studied in recent years due to their large variety of applications such as medicine, biology, catalysis, material sciences and chemical analysis. Ruthenium polypyridyl complexes have been extensively studied for their applications as photosensitizers in solar energy conversion and photoelectronic materials. Recently, ruthenium heterocyclic ligand complex-based building blocks have been used for the synthesis of hybrid organic-inorganic solids through the self-assembly. We are

This thesis is divided into four major parts. The first part describes a simple method to measure the content of reactive hydroxyls of various amorphous silicas before and after thermal treatment. The reaction of excess VOCl3 vapor with surface OH groups of partially dehydroxylated silica is rapid and quantitative. Regardless of the degree of dehydroxylation, the stoichiometry of the reaction is invariable, as demonstrated by 51V magic angle spinning NMR spectroscopy and X-ray absorption spectroscopy (XAS). Using this method, we have quantified the reacive hydroxyls of fumed and precipitated

Chlorofluorocarbons were once commonly used as propellants and refrigerants due to their stability, low toxicity and excellent physical properties. They were phased out, however, after being identified as ozone-depleters, and have been replaced by hydrofluorocarbons (HFCs) and other fluorocarbon derivatives (FCDs). The high temperature-resistant characteristic of these materials is beneficial for many applications; however, the robust nature of the C-F bonds leads to their persistence in the environment. Frequently, the synthesis of HFCs and FCDs involves energy-intensive processes and toxic p

The novel fluorescent nanostructures are synthesized in a simple one-step process by UV light illumination of silver salt in a mixture with organic dye Thioflavin T. The latter serves both as a sensitizer in photoreaction and as molecular support. The most stable composite structures are obtained in 2-propanol. They are characterized by absorption spectra that are quite different from that of the dye and by strong excitation and emission bands with the maxima at 340 nm and 450 nm correspondingly.

Metal-organic frameworks are a new class of crystalline, porous solid-state materials with metal ions periodically linked by organic linkers. This gives rise to one-, two- or three-dimensional structures. Here, we compare the stability of similar metal sites toward external ligand (solvent) induced disruption of the coordination environment in metal complexes and in metal-organic frameworks. Our experimental results show that a metal site as node of a metal-organic framework retains much higher stability compared to a similar metal site in a metal complex.

Popular catalytic cycles, such as the Heck, Suzuki, and Negishi, utilize metal centers that oscillate between two oxidation states (II/0) during the three main steps of catalysis: reductive elimination, oxidative addition, and transmetallation. There has been a push to use less toxic, cheaper metal centers in catalytic cycles, leading to interest in first-row transition metals, such as nickel and cobalt. With these metals, the cycles can potentially pass through the +1 oxidation state, which acts as reactive intermediates, undergoing oxidative additions to form products, potentially with radic

Vingt-quatre nouveaux complexes d'halogénures de métaux 3 D : mx::(2) (m = co,ni,cu; x = cl,br) sont préparés et caractérisés. Leurs structures sont déterminées par diffraction des rayons X pour deux des composés et, à partir de celles-ci, pour l'ensemble des complexes grâce à la spectroscopie infrarouge et à la spectroscopie électronique. Le calcul des constantes de stabilité et des paramètres thermodynamiques correspondants par titrimétrie thermométrique est décrit.

L'etude des proprietes redox d'une vingtaine de complexes mono-, di-, tri- et tetranucleaires du palladium et du platine a ete effectuee par des methodes electrochimiques (electrode a disque tournant, voltamperometrie cyclique et coulometrie) associees a des methodes spectroscopiques (spectrophotometrie d'absorption electronique, rpe et rmn). Les differents mecanismes des reactions redox ont ete etablis en fonction de la nature des metaux et des ligands dans le complexe. On montre qu'on peut modifier de maniere controlee les potentiels d'oxydoreduction et la reversibilite des transferts de cha

Les ligands carbéniques N-hétérocycliques sont généralement décrits comme des analogues aux ligands phosphines car ils présentent des propriétés électroniques comparables, bien que leur caractère σ-donneur soit plus prononcé. Ils ont donc été utilisés pour la synthèse de complexes organométalliques en remplacement des ligands phosphines et un nombre très important de complexes métal-NHC ont été développés ces 15 dernières années. Toutefois, ces complexes bien que très actifs dans de nombreuses réactions catalytiques clefs (métathèse des oléfines, couplages C-C, échange H/D…), présentent des pr
