摘要: 介孔硅基有机无机杂化材料(PMOs)是一种分子水平上有机组分与无机组分在孔壁中杂化的材料, 这类材料有着许多独特的性质:有机官能团均匀分布在孔壁中且不堵塞孔道, 有利于客体分子的引入和扩散; 骨架中的有机官能团可以在一定程度上调节材料的物化性质, 如机械性能, 亲/疏水性; 可以同时实现对孔道和孔壁功能性的调变. 正因如此, PMOs已成为当今材料科学领域的一个研究热点. 本文综述了PMOs 的最新研究进展, 包括其合成方法、表征及其在催化、吸附、分离、光电等领域的应用. 最后展望了该类材料的发展前景.

Abstract:

The integration of organic and inorganic fragments within the pore wall of the periodic mesoporous organosilicas (PMOs) represents one of the recent breakthroughs in the fields of material science. The organic moieties distributed uniformly in the mesoporous framework will not block the pore, which is beneficial to the diffusion of guest molecule. The surface hydrophilicity/hydrophobicity, mechanical and hydrothermal stability of the PMOs could be easily tuned. The unique features of the PMOs make them attractive in many applications. The recent progresses in the synthesis, characterization and application of the PMOs are summarized, with special emphasis on their applications in catalysis, adsorption, separation, and photoelectricity. The future development of the PMOs is also prospected.
