周期性介孔有机官能化氧化硅材料(PMOs)表面修饰的研究现状

Latest Development of Terminal Functionalization of Periodic Mesoporous Organosilicas

综述了周期性介孔有机官能化氧化硅材料(PMOs)及其表面修饰的研究现状。PMOs的结构与性能取决于有机硅前驱体中有机桥联基团的种类。分布在骨架和孔道内的有机官能基团由于所处的环境以及基团种类的不同,将表现出不同的化学特性,从而赋予材料不同的化学和物理性能。所以近年来,国际上很多研究人员采用不同的官能团对PMOs的孔结构进行修饰,以期获得性能更为优异的新型介孔材料。

In the present paper, the latest development of the synthesis and terminal organo-functionalization of periodic mesoporous organosilicas （PMOs） is reviewed in detail. The structure and properties of PMOs depend on the class of bridging organic groups covalently linked to silicon atoms within organosilane precursors. Functional organic groups inside the framework and the channel pores present different chemical properties due to their different chemi cal environment , thus leading to hybrid mesoporous materials exhibiting different physical and chemical properties. Therefore, various functional organic groups have been used to terminally functionalize periodic mesoporous materials by many researchers in recent years, in order to expand the properties of PMOs materials.
