activités de recherche

Yann Molard obtained his PhD degree in 2000 at the University Claude Bernard Lyon 1 (France) under the supervision of Pr. Helene Parrot-Lopez and Pr. Jean-Bernard Regnouf de Vains in the field of Supramolecular chemistry. He modified calixarene with polypyridinyl ligands and studied their complexation behaviour towards metallic cation. Then, he obtained a non permanent position of lecturer in the same university (1 year, 00/01) and worked on molecular modelling of catalysts grafted on oxyde surface with Dr. J. M. Basset. Later, he went to the engineering school INSA Lyon for another non permanent lecturer position (1 year, 02/03) and worked with Pr. Jean Francois Gerard and Dr. Jocelyne Galy(Laboratory of Macromolecular Material) on the molecular modelling of interactions between polymers and non-modified and modified silica surfaces.
He went back to supramolecular chemistry by taking during two years a post doctoral research associate position in the Jim Tucker's group in UK where he developped anthracene containing molecular photoswitchable receptors for neutral guest. This subject gave him the opportunity to collaborate with Dr. J.P. Desvergne and Dr. D. Bassani in Bordeaux where he spent around six months.

He joined the solid state chemistry and material team of the University Rennes 1 as lecturer in September 2005. His research interests are focused now on the modification of octahedral metallic clusters with organic or organometallic ligands in order to assemble them in an appropriate way to obtain new materials with specific properties. The behaviours of those nano organised materials depend on the interaction between clusters and ligands.
