Résumé
I will present a fundamental study of the nanostructuring mechanisms of organic–inorganic nanohybrids namely bridged silsesquioxanes. Our experimental investigation was performed using an in operando approach (vibrational spectroscopies under pressure, light diffusion, microscopy) coupled to DFT calculations. Parameters controlling the evolution of the system during sol−gel processing: self-assembly, hydrolysis, polycondensation, and nucleation and growth of the hybrid solid in solution were investigated. The relationship between structural properties and applications will be then highlighted [1,2]. References[1] G. Creff et al. Langmuir 2013, 29, 5581-5588[2] R. Le Parc, et al.
