Abstract

C60-polysiloxane hybrids were prepared by the reaction of triethoxysilylated C60 (TES-C60) with methylpolysiloxane (MPS) or α,ω -dihydroxypolydimethylsiloxane (STPDS). TES-C60 was synthesized by hydrosilylation using triethoxysilane and C60 in the presence of chloroplatinic acid. TES-C60 was mixed with MPS and heated to provide a bulk body of C60 containing polysiloxane hybrid in a Si/C60 molar ratio of 1000:500. The formation of this hybrid is based on the hydrolytic polycondensation of TES-C60 and MPS to fix C60 into the silica matrix by a chemical bond. TES-C60 and STPDS also provide an isolatable thin film of C60 containing polysiloxane hybrid by an ethanol-forming condensation reaction. Because no gelation was observed when only STPDS was aged, it is thought that TES-C60 serves as a cross-linking point in gel formation.
