As our studies showed, silylation of mesoporous molecular sieves with alkoxysilane was an usual method of linking desired organical groups. However, as a result, the a lot of silanol groups still existed on the surface of mosoporous molecular sieves after silylation, which maybe affect the interface property and its catalystic activity. Based on this consideration, a novel method was proposed that a mixture of trichlorosilanes was used to silylate mesoporous molecular sieves, introducing both the further reactive group and hyhrophobic methyl group in one pot.

正如研究表明，通过硅氧烷与介孔分子筛表面的硅羟基反应是常见的键连有机基团的方法，但表面仍会剩余较多的硅羟基，硅羟基的存在会严重影响到介孔分子筛表面性质及催化活性，为此笔者提出采用混合的三氯化硅烷一步硅烷化介孔分子筛，在孔道内同时引入可进一步功能化的氯丙基或氯苄基和疏水性的甲基。
