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,...

Thèse de doctorat : Université de Neuchâtel, 2012.
Ce travail de thèse traite de la conception de nouveaux matériaux mésomorphes basée sur la métathèse croisée ou sur la combinaison de la chimie click et de la métathèse croisée. Les dendrons cyanobiphényles, poly(aryl esters) nématiques chiraux et poly(aliphatique esters) smectiques chiraux ont été choisis pour obtenir des composés formant des mésophases chirales. Les...
