Abstract:
A process for preparing structured organic-inorganic hybrid materials, comprising the steps:(a) forming a mixture comprising at least one mesophase of an amphiphilic organic block copolymer consisting essentially of at least one hydrophilic block and at least one hydrophobic block as template and comprising at least one precursor which can be reacted to give an inorganic solid, (b) reacting the precursor in a bulk phase or in a mesophase that is free from solvent, and (c) optionally removing any volatile constituents from the reaction mixture, to produce the organic-inorganic hybrid material, wherein a hydrophobic block in the amphiphilic block copolymer has a glass transition temperature of Tg&lE;50Â° C.
