Development and Applications of Covalent Organic Frameworks(COFs)Materials:Gas Storage,Catalysis and Chemical Sensing

共价有机框架材料(Covalent Organic Frameworks,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。作为一类新型的结晶性有机多孔材料,由于其密度低、比表面积大、孔隙率高、结晶度好、稳定性高及结构单元可设计等特点受到科学界的广泛关注,在气体吸附与分离、光电、催化、药物传递、储能及化学传感与色谱分离等领域表现出良好的应用前景。本文对COFs材料的发展与应用研究进展进行了简要的综述,对COFs应用中尚待解决的问题进行了总结并对未来的发展方向进行了展望。

Covalent organic frameworks（ COFs） are porous compounds with periodic topology structures in which the organic building units are linked by covalent bonds. As a newtype of crystalline porous organic materials with multiple advantages,such as lowdensity,large surface area,porosity,good crystallinity,high stability,designable structural units and so on,they have won more and more attention of scientists and been widely applied in many fields including gas adsorption and separation,optoelectronic device,catalysis,drug delivery,energy storage,chemical sensing and chromatographic separation. In the present paper,development and application advances of COFs materials are reviewed in outline, the burning issues concerning the applications are summarized and their possible development trends are also prospected.
