Sol-gel processed polysilsesquioxanes are hybrid organic-inorganic materials with potential applications as photoresists, membranes, or catalytic supports. Hydrolytic conversion of trichloro- or trialkoxysilanes often leads to amorphous or crystalline oligosilsesquioxanes instead of high polymers. In light of the intimate dependence of polysilsesquioxane properties of tightly controlled reaction conditions and processing, recent emphasis has been placed on control of polymer microarchitecture via the introduction of arylene-, acetylene-, and alkylene-bridging groups. Another strategy for modifying the properties of hybrid organic-inorganic polymers is to substitute a group IVA metal, such as germanium, for silicon. The authors report the synthesis and characterization of bifunctional hexylene-bridged organogermanium monomers X[sub 3]Ge-(CH[sub 2])[sub 6]GeX[sub 3] (X = Cl; OEt) and the formation of polymeric materials through sol-gel hydrolysis-condensation of the monomers. 15 refs., 2 figs.
