摘　　要：共价有机框架材料(COFs)是由有机结构单元通过共价键连接的具有周期性结构的多孔化合物。COFs具有永久的孔隙、高的比表面积、可调的孔径、易于功能化和高的水热稳定性等优点,广泛应用于许多领域。本文总结了COFs目前主要的合成方法,介绍了COFs在吸附领域的应用和发展。最后,文章指出未来的研究重点是发展更多有机反应和键连方式,合成具有高度稳定性和结晶度、成本低廉的功能性材料。Covalent organic frameworks(COFs)are porous compounds with periodic structure,which are connected by organic structural units through covalent bonds.Covalent organic framework materials are widely used in many fields because of their permanent pore structure,large surface area,tunable pore size,easy functionalization and high hydrothermal stability.In this paper,the main synthesis methods of COFs at present are summarized,and the application and development of COFs in adsorption field are introduced.Finally,it is pointed out that future research should be focused on developing new organic reactions and the building units to synthesize low-cost functional materials with high stability and crystallinity.
