Conception de matériaux dendritiques chiraux mésomorphes pour l’élaboration de commutateurs électroactifs basés sur le couple ferrocène/ferrocenium

Kopp, Cyril ; Deschenaux, Robert (Dir.) ; Süss-Find, Georg (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2010.

This thesis focuses on the design of new mesomorphic materials. Two chiral dendrimers were synthesized with the aim to transfer their liquid-crystalline properties to ferrocene derivatives. An evolution towards peralkylated ferrocene gave stable ferrocenium derivatives showing a switch between liquid-crystalline phases. The role of the dendritic structure and oxidation could be explained. Then,...

Conception de dendrimères liquides-cristallins pour la fonctionnalisation de nanoparticules d'or et de composés inorganiques et organiques

Frein, Stéphane ; Deschenaux, Robert (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2009 ; Th. 2118.

The main objective of the thesis is the design of liquid-crystalline dendrimers for the functionalization of various organic and organometallic moieties including gold nanoparticles, fullerene, diruthenium clusters, fluorescent dyes and carbon nanotubes. Three different families of dendrimers were prepared: poly(aryl ester) dendrimers functionalized with cyanobiphenyl mesogenic units (smectic and...
