Abstract

See full text

The invention concerns a preparation process of a hybrid organic-inorganic material including the following successive steps:

    a) preparation of a neutral organosilicon sol in at least one organic solvent,b) incorporation of a doping agent into the neutral organosiliconsol, and production of a doped sol,c) incorporation into the doped sol, of an accelerating agent in order to activate the subsequent gelation of the sol,d) condensation of the sol in order to obtain a crosslinked gel,e) drying of the gel and production of a stable doped gel.and the material obtainable by such a method.
