有机框架材料的后合成交换

Post-synthetic exchange of organic frameworks

金属-有机框架(MOFs)和共价-有机框架(COFs)材料是近年发展起来的晶态多孔材料,因其独特的孔道结构、大的比表面积和易功能化等特点,在催化、储能和传感器等领域有着巨大的应用前景。后合成交换是MOFs/COFs材料进行化学修饰有效方法之一,部分材料可在不改变原拓扑结构的前提下,精准实现材料的功能化,在MOFs/COFs的结构设计和应用方面有十分重要的作用。本文总结了后合成交换在MOFs/COFs材料方面的最新研究进展,包括交换机理及影响因素、方法优势及应用等,为MOFs/COFs材料的结构调控和功能化提供思路。

Metal organic frameworks(MOFs) and covalent organic frameworks(COFs) as new crystalline porous materials have developed in recent years. MOFs/COFs materials have shown great application potential in the fields of catalysis, energy storage and sensor because of their unique pore structures, larger specific surface areas and easier functionalization characteristics. Post-synthesis exchange as an effective chemical modification method of MOFs/COFs materials plays an important role in the structural design and application of MOFs/COFs materials, it could accomplish the accurately functionalization without changing the original topological structure in some MOFs/COFs. This review presents the latest research progress of post-synthesis exchange in MOFs/COFs materials, including exchange mechanism and the factors affecting the exchange efficiency, as well as their advantages and potential application etc. This review provide new ideas for the structural design and functionalization of MOFs/COFS materials.
