The aim of this thesis work is to combine self-organizing liquid-crystalline dendrimers with isotropic components, such as C60 and rotaxane to create complexes supramolecular architectures of interests for optoelectronic applications. This work is intended to rationalize the relation between molecular design and liquid-crystalline properties, with emphasis on the influence of isotropic...

In this thesis, the topic was the design of liquid-crystalline bisfullerodendrimers. Indeed, the field of liquid-crystalline fullerodendrimers is being extensively investigated. Combining [60]fullerene (C60) with liquid crystal organization give numerous applications in the field of self-assembled supramolecular materials. Currently, the mesomorphic fullerodendrimers are made of only...

Notre travail de thèse concerne la synthèse de nouvelles macromolécules mésomorphes contenant du fullerène (C60) ou du ferrocène et l’étude de leurs propriétés liquides-cristallines. Ce travail est basé sur trois sujets différents. Dans le premier sujet, nous nous intéressons à la synthèse de matériaux photo-actifs à base de polymères liquides-cristallins et du...

The aim of this thesis is to combine metals and dendrimers to obtain mesomorphic or biological properties. The design of metamaterials from gold nanoparticles is still a challenge as the spatial organisation is difficult to control. Thus, the combination of gold nanoparticles with liquid-crystalline dendrimers is a way to explore the organisation of such systems in mesophases. We...

Our research project deals with the design of liquid-crystalline materials based on the 1,3-dipolar cycloaddition reaction, i.e. the click chemistry. This reaction was found to be effective and versatile, and a great variety of new complex structures could be synthesized, including dendrimers, dendromesogens, gold nanoparticles and polyadducts of fullerenes. In the area of mesomorphic...

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,...

Notre thématique de recherche concerne la chimie des cristaux liquides. Nos travaux de thèse consistent en la synthèse de dendrimères liquides-cristallins contenant du fullerène et l’étude de leurs propriétés thermiques et mésomorphes. Ce type de matériaux est intéressant par la combinaison des propriétés du fullerène avec celles des cristaux liquides et des dendrimères. Notre...

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...
