Abstract
Organic-inorganic hybrid films containing organosilica nano-crystals have been obtained by an alcohol-free hydrolytic sol-gel process from a mono-functionalized organically modified alkoxide. Kinetically controlled self-organization has been used to design the hybrid nanocomposite films; nanocrystals of around 100 nm in diameter and 4 nm in thickness have been formed in transparent hybrid films. The layered nanocrystals have shown to be oriented within the films which exhibited an optical anisotropy (dn>10-3); the hybrid nanocomposite material has shown to be suitable for micro/nanofabrication by soft lithography and different patterned structured containing the hybrid nanocrystals have been obtained
