INCORPORATED C70 IN SOL AND GEL

Abstract

C70 is incorporated in gel by a sol-gel process with using 3-amino-propyltriethoxysilane (NH2(CH2)3Si(OC2H5)3, APTS) and 3-glycidoxypropltrimethoxysilane (CH2OCHCH2O(CH2)3Si(OCH3)3, GPTMS) as precursors. C70 is firstly mixed with APTS to form C70-NH2(CH2)3Si(OC2H5)3 compound by the reaction between C70 and amino-group of APTS, and then the compound is hybridized with GPTMS to form solid gel. The linkage of C70 and APTS is estimated and confirmed with FT-IR spectra, and the UV/Visible spectra of the sol and gel are measured.
