一、引言 近年来，对溶胶-凝胶法合成含有机基团的硅酸盐（Organically Modified Sllicatos)材料已有不少报导~（[1～4]）。作者曾用此法合成了数种含苯基的硅酸盐材料~[5]，并制成薄膜研究了它们的化学稳定性~[6]。
I. INTRODUCTION In recent years, many reports have been made on the synthesis of Organically Modified Sllicatos (SOL) materials by sol-gel method. The authors have used this method to synthesize a number of phenyl-containing silicate materials [5], and made of thin films to study their chemical stability ~ [6].
