Abstract:
Donor-acceptor Stenhouse adducts (DASAs) are a photo-switch class that undergoes triene cyclisation in response to visible light. Herein, electrochemical oxidation is demonstrated as an effective alternative stimulus for the triene cyclisation commonly associated with photo-switching.

Abstract:
AbstractUnderstanding the intricate relationship between molecular architecture and function underpins most challenges at the forefront of chemical innovation. Bond-forming reactions are particularly influenced by the topology of a chemical structure, both on small molecule scale and in larger macromolecular frameworks. Herein, we elucidate the impact that molecular architecture has on the photo-induced cyclisations of a series of monodisperse macromolecules with defined spacers between photodimerisable moieties, and examine the relationship between propensity for intramolecular cyclisation an

Abstract:
L’objectif de cette thèse est de développer des matériaux souples supramoléculaires sensibles aux stimuli électrochimiques. La stratégie de préparation et de stimulation de tels matériaux est basée sur les propriétés d’auto-assemblage d’unités moléculaires dérivés de sels de 4,4-bipyridinium (viologènes). Ce travail de thèse développe en particulier l’étude de la structure, le mécanisme de formation et la stimulation par transfert d’électrons de gels supramoléculaires conducteurs obtenus par auto-assemblage d’un viologène substitué par des groupements cholestéryles.
