Synthesis of Organic−Inorganic Polymer Hybrids Having Interpenetrating Polymer Network Structure by Formation of Ruthenium−Bipyridyl Complex

Abstract

Organic−inorganic polymer hybrids were prepared by an in-situ method. In the presence of ruthenium salt, the cross-linking reaction of bipyridyl-containing polymer was carried out together with the sol−gel reaction of tetramethoxysilane. This methodology includes the simultaneous formation of silica gel and organic gel. Using polystyrene or poly(ethylene oxide) having bipyridyl groups, organic−inorganic polymer hybrids could be prepared. The obtained polymer hybrids having IPN (interpenetrating polymer network) structure showed excellent solvent-resistant property.
