Abstract

Copolymerization of cubane octavinylsilsesquioxane, {Si8O12}(CH=CH2)8, with the cubane silses-quioxane hydrides, {Si8O12}H8 and {Si8O12}(OSiMe2H)8 in the presence of C5H5Rh(CO)2 affords hybrid inorganic-organic copolymers incorporating monocarbonyl {C5H5Rh(CO)} species. These are of two types, one containing Rh(III) and the other Rh(I). The Rh(III) species appears to be that formed initially, and can be converted into the Rh(I) species by photolysis. BET measurements show that a significant increase in surface area occurs when the copolymerization is carried out in the presence of the rhodium complex.
