Silica-based hybrid materials

This thematic focuses on the synthesis, organization and characterization of silica-based organic-inorganic hybrid materials. In this view, the sol-gel process is ideally suited, allowing us to synthesize metastable materials with controlled texture, morphology, and functionality. With this process, any kind of organic or bioorganic group (e.g. sugar, peptide) can be accommodated in the final material, the structure of which can be controlled at the micro- and nano-meter level, by playing on supramolecular interactions in solution (for instance by adding organic templating agents.

The control of architecture and of localization at nanometer scale of functional groups is a major goal in the design of advanced materials, whether to generate a collective property (e.g. ionic conduction) or  to improve th accessibility to functional sites (e.g. through a better dispersion) and their efficiency (e.g. identical sites rather than a distribution, for instance for catalysis, molecular recognition or biological activity).


The use of ionic liquids, which are both structured and structurating media, with remarkable properties (thermal stability, extremely low vapor tension, high conductivity, outstanding solvents, etc.) or of precursors inspired from ionic liquids is a major axis of the group, further widening the possibilities of hybrid materials (ionogels, ionosilicas).
