利用溶胶-凝胶法制备新材料引起了人们极大的兴趣。1 r7溶胶凝胶衍生的硅酸盐材料通常通过在催化剂（H+，OHr）的存在下水解和缩合烷氧基硅烷（即四甲氧基硅烷（TMOS））来制备，如下面给出的简化反应方案所示：8特定试剂可以被捕获到这种稳定的主体中，只需在其凝胶化之前简单地将它们添加到溶胶中。1 r3 Solrgel衍生材料具有许多有用的特性，包括光学透明性、光化学和电化学稳定性以及优异的加工能力。在众多的应用中，溶胶凝胶衍生的材料已用于开发化学传感器，2，3，9色谱固定相，10和光学脱附。
Considerable interest has been given to the fabrication of new materials using the solrgel process. 1r7 Solrgelderived silicate materials are typically prepared by hydrolyzing and condensing an alkoxysilane (ie, tetramethoxysilane (TMOS)) in the presence of a catalyst (H+, OHr), as depicted in the simplified reaction scheme given below: 8Specific reagents can be entrapped into this stable host just by simply adding them to the sol prior to its gelation. 1r3 Solrgel-derived materials have many useful properties that include optical transparency, photochemical and electrochemical stability, and excellent processing abilities. 1r3 Among numerous applications, solrgel-derived materials have been used to develop chemical sensors, 2, 3, 9 chromatographic stationary phases, 10 and optical de-
