一类有趣的材料是介孔有机二氧化硅材料，沿孔表面含有桥联的有机基团。这种材料由(R‘O)3Si-R-Si(OR’)3型倍半硅氧烷前驱体制备，其中R是感兴趣的桥联有机基团，与溶致相结合作为用于产生孔的模板。介绍了一种新的倍半硅氧烷前驱体1，3-双(三烷氧基硅基)-5-溴苯，以及相关的孔壁含溴苯基的介孔有机硅材料。后一种前体允许进行卤代芳香族化合物的衍生化反应。含有苯衍生物的材料可以通过在分子尺度上从上述前体开始进行化学修饰来获得，或者可以直接在多孔材料的表面上进行修饰。描述了表面含有苯甲酸、苯乙烯和苯基膦酸的材料。
An interesting class of materials is mesoporous organosilica materials containing a bridging, organic group along the pore‐surface. Such materials are prepared from silsesquioxane precursors of the type (R′O)3Si‐R‐Si(OR′)3where R is the bridging organic group of interest, in combination with a lyotropic phase as a template for the generation of the pores. A new silsesquioxane precursor, 1,3‐bis‐(trialkoxysilyl)‐5‐bromobenzene, and the related mesoporous organosilica material containing bromobenzene groups located at the pore walls are presented in the current publication. The latter precursor allows access to the derivatization reactions known for halogenated aromatic compounds. Materials containing phenyl derivatives can be obtained either by chemical modifications starting from the mentioned precursor on the molecular scale, or the modifications can be performed directly at the surfaces of the porous material. Materials with surfaces containing benzoic acid, styrene, and phenylphosphonic acid are described.
