Molecule oriented supraparticular chemistry

Nanoobjects are more and more subject of interest in academic and industrial research. However, most of the studies essentially focalize on the properties of individual objects. Indeed, a key challenge to study collective properties – opening doors to new applications – is the organization of such objects at large scale. So far, most of the reports considered nanoparticle self-assembly as a packing of hard spheres. As supramolecular chemistry brought new properties to molecular materials fifty years ago, our goal is to take part in the development of supraparticular chemistry, i.e. oriented self-assembly of nanoparticles, by controlling the interactions between the ligands that stabilize the nanoparticles, and between the ligands and the surface of the nanoparticles. Examples will be based on ultra-small platinum nanoparticles as building blocks, combined with different molecular entities: simple molecules, coordination complexes, peptidic polymers, coordination networks, etc. The goal will first be to describe the formation of the superstructures, and then to elaborate functional systems in charge transport, eventually responsive to external parameters: light, temperature, co-solvent, etc.
