"From ionic liquids to nanostructured ionic solids: Ionosilicas as "Designer materials"

Abstract. Silica based materials containing covalently anchored ionic groups are called ionosilicas. Our special concern are purely ionic-inorganic silica hybrids, obtained via hydrolysis-polycondensation reactions exclusively from silylated ionic precursors. These phases can be considered as heterogenized Ionic Liquids; they combine the characteristics of mesoporous silicas (porosity, regular architecture on the mesoscopic scale) and the unmatched chemical versatility of ionic liquids.

This talk will focus on the extraordinary polyvalence of ionosilicas. On the one side, the texture and morphology of ionosilicas can be controlled, and various shapes such as ionosilica nanoparticles, monoliths or fibers can be synthesized. On the other side, ionosilicas are functional materials with promising properties for various applications. We will illustrate the polyvalence of ionosilicas by two case studies in drug delivery and organocatalysis.
