Organic‐inorganic hybrid films containing layered organosilica nanocrystals are obtained by an alcohol‐free hydrolytic sol‐gel process from a mono‐functionalized organically modified alkoxide. Kinetically controlled self‐organization is used to design the hybrid nanocomposite films. The layered nanocrystals are shown to be oriented within the films, which exhibited optical anisotropy (Δ n > 10 −3 ); the hybrid nanocomposite material is shown to be suitable for microfabrication by soft lithography.
