Le cancer, une maladie maligne, est l’une des principales causes de mortalité et de morbidité chez l’homme. Cependant, le ciblage sélectif des tissus cancéreux reste un défi. L'effet de perméabilité et de rétention accrue (effet EPR) est un phénomène naturel dans les tissus cancéreux solides qui est observé pour les structures moléculaires grandes et lourdes. Il constitue donc...

The olefin cross-metathesis reaction using the second-generation Grubbs catalyst was employed to prepare non-symmetrical thermotropic liquid crystals from various mesomorphic or nonmesomorphic type I and type II olefinic constructs, including linear, chiral, dendritic and ferrocenyl olefins. Smectic C, smectic A and nematic phases, as well as chiral smectic A and chiral nematic phases were...

Pillar[5]arene-based [2]rotaxanes have been prepared from the reactions of diacyl chloride reagents with various amine stoppers. The yields of the [2]rotaxanes are sensitive to the reaction conditions (solvent and stoichiometry) as well as to structural and electronic factors. In particular, the nature of the starting amine reagent has a dramatic influence on the yields of [2]rotaxanes; thus,...

Solution spectroscopic investigations into the interactions of eight potential bidentate V-series organophosphorus chemical warfare agent (OP CWA) simulants with [Eu(phen)₂(NO₃)₃]·2H₂O demonstrated that the chemical and structural composition of the secondary binding site within the simulant was of paramount importance. Only simulants containing both phosphoryl/phosphonyl and...

The work presented in this thesis involves the synthesis and characterization of dinuclear ruthenium, rhodium and iridium complexes. The catalytic, supramolecular and biological applications of these dinuclear complexes will be discussed. In the first part, the synthesis of sawhorse-type diruthenium tetracarbonyl complexes and their catalytic applications in the supercritical carbon dioxide...
