摘要
PMOs是以桥联倍半硅氧烷为前驱体,在表面活性剂为结构控制剂的条件下通过溶胶-凝胶法合成的材料,具有表面积高、孔道规则和孔径分布较窄等特点,是一种性能优异的新型功能材料。本文论述了PMOs近年来的发展现状,介绍了PMOs的结构特点,根据结构中桥联有机基团的不同将其分为三类;总结了通过不同的模板合成PMOs的方法,并对影响性能的外部因素进行了探讨;最后提出了几个PMOs研究工作面临的问题,并对PMOs的发展前景做了展望。
Periodic mesoporous organosilicas（PMOs） are prepared using bridged silsesquioxanes as the precursors and surfactants as the structure-directing species via sol-gel route.They are novel functional materials with many excellent and special properties,such as high surface area,ordered pore channel,sharp pore size distributions,and so on.In this paper,the main advances in the research of PMOs in recent years are reviewed.The structural characteristics are particularly introduced.Then according to the different organic bridging groups incorporated into the structures,the PMOs are classified into three classes.The synthesis of PMOs with different templates is introduced and the exterior factors which influence the properties are discussed.At last,the difficulties of research on PMOs are mentioned,and the development prospect is looked forward.
