Couplage mouvement et catalyse : développement de systèmes moléculaires dynamiques contrôlés par des effecteurs chimiques et lumineux

Abstract : With a constant desire to understand and develop molecular engineering, scientists have conceived and produced a wealth of systems, similar to the ones we are confronted with everyday. In this work, organic synthesis strategies are presented for the preparation of switchable molecular turnstiles. The goal was to introduce catalytic sites and to follow their activity under controlled conditions. From multi-step and optimized routes, several families were synthesized, characterized and their catalytic activites were evaluated. In the meantime, interest was focused on the modulation of kinetics in such systems. Photo-isomerizable compounds were prepared and characterized by NMR, and later examined with photo-physics and theoretical approaches. Eager to build up organized objects, coordination networks were finally prepared from photo-sensitive ligands.
