Multifunctional polysilsesquioxane

A new family of polysilsesquioxane colloids was synthesized by hydrolytic condensation of different functional amphiphilic silanes without any additional surfactants [58-60]. To choose a suitable monosubstituted silane, we looked for the combination of a functional group, which would be able to interact with metal compounds, and a hydrophobic part, which would self-assemble in an aqueous medium. We expected that a sol-gel reaction of such a precursor in water would yield multifunctional materials with internal ordering if the hydrophobic tail is sufficiently long. In this way, polysilsesquioxane colloids...
