Thèse de doctorat : Université de Neuchâtel, 2017.

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...

Heterotelechelic polymers were synthesized by a kinetic telechelic ring-opening metathesis polymerization method relying on the regioselective cross-metathesis of the propagating Grubbs’ first-generation catalyst with cinnamyl alcohol derivatives. This procedure allowed the synthesis of hetero-bis-end-functional polymers in a one- pot setup. The molecular weight of the polymers could be...
