Thin glass-like ceramic films which possess organic or physically functional structures with thicknesses in the 15 to 500 nm range and bottom-up methods for their fabrication are described. SiO2-rich structures having gradient properties are formed from a silsesquioxane having an electronegative β substituent and at least one organofunctional silane or at least one metal alkoxide.
