共价有机框架材料制备与应用的研究进展

Progress of Synthesis and Application of Covalent Organic Frameworks

共价有机框架(COFs)材料是由各种有机构筑基元通过可逆共价键连接而成的高比表面积晶形有机多孔材料.COFs材料以其结构规整、孔道均一、密度低、热稳定性和化学稳定性好等优点,而引起人们的关注.本文介绍了COFs材料的基本概念并综述了其构筑基元、构建方式和制备方法,以及COFs材料在气体储存、催化、光电等方面的应用,展望了COFs材料在这些领域的研究发展趋势.

Covalent organic frameworks （COFs） are a class of crystalline porous polymers that allow the atomically precise integration of organic units to create predesigned skeletons and nano-pores. Since the seminal work of Yaghi on covalent organic frameworks, this subject has attracted extensive interest not only from chemists＇ science and organic synthesis, but also from various researchers in the fields of gas storage, heterogeneous catalysis, semi-conduction and photoconduction. This review describes the building blocks of COFs and synthetic methods. The applications are also studied and evaluated. Concerning COFs for future research, some suggestions are proposed and conclusions are given.
