Molecules are self-assembled into monolayers on silicon surfaces with an extreme control so that we can avoid any oxidation of silicon, even at room pressure. We have especially studied the case of Grafted Organic Monolayers (GOM) on oxide-free silicon and have developed a chemistry to graft gold nanoparticles or POM (polyoxometallate). This last aspect is a collaboration with Pr. A. Proust (Sorbonne Université). POM such as PM12O40, with M = W(+VI) or Mo(+VI) are investigated. These POMs can be oxidized or reduced without any geometrical change. In other words, they can store charges at an extremely high density without any changes and have huge application in molecular electronics.
