Abstract

Polyoxometalates (POMs) are molecular oxides built on transition metals of groups 5 and 6. They display an incredible variety of molecular structures and remarkable properties, which lead to applications in various fields such as analytical chemistry, catalysis and materials science. The group in Paris has gained expertise in the functionalization and post-functionalization of POMs, namely the elaboration of POM based organic-inorganic hybrids. I will present some advanced architectures together with their application in artificial photosyntheses (hydrogen evolving reaction) and the characterization of electron transfer to and through a POM monolayer grafted on solid substrates.
