Bridged polysilsesquioxanes: A molecular based approach for the synthesis of functional hybrid materials

Shea, Kenneth J.; Loy, Douglas A.

Bridged polysilsesquioxanes (BPS) are a family of hybrid organic-inorganic materials prepared by sol-gel polymerization of molecular building blocks that contain a variable organic component and at least two trifunctional silyl groups. The synthesis of functional BPS is presented. Dipropylene and diisobutylene carbonate-bridging groups are successfully used as masked hydroxyalkyl and allylic substituents in polysilsequioxane gels and the nature of the substituents is controlled through the surface modification of the gels prior to heat treatment.
