Abstract:
1. A process for preparing photoresponsive hybrid organic-inorganic particles comprising (a) combining (1) at least one organosilane compound and (2) at least one photoactive material to form a neat ceramic precursor composition, wherein wherein each R is independently selected from alkyl, alkenyl, acyl, cycloalkyl, aryl, heteroalkyl, heteroalkenyl, heterocycloalkyl, heteroaryl, and combinations thereof; each X is independently selected from a halogen atom, a hydrogen atom, acyloxy, alkoxy, hydroxyl, and combinations thereof; and p is an integer of 2 or 3, and (b) allowing or inducing hydrolysis and condensation of said organosilane compound to form hybrid organic-inorganic particles comprising said photoactive material, wherein the hydrolysis and condensation are effected by combining, in the absence of an organic solvent, the neat ceramic precursor composition with an aqueous composition comprising at least one catalyst and at least one surfactant.
