摘　　要：共价有机骨架(COFs)作为一类新颖的、结晶性的、通过共价键构建而成的多孔聚合物材料。由于其稳定的化学性质、巨大的比表面积及可调控的孔道结构,还兼有易于功能化和快速的载流子迁移率等特点,已被成功应用于样品前处理中。然而,很少有关于COFs在固相微萃取(SPME)方面的研究进展。本文主要综述了制备方法、萃取机理及在环境污染物方面的应用的最新研究进展,并对其发展趋势进行了展望。Covalent organic frameworks(COFs)are a kind of novel,crystalline and porous polymer materials constructed by covalent bonds.Due to its stable chemical properties,large specific surface area,controllable pore structure,easy functionality and fast charge-carrier mobility,it has shown great potential in sample pretreatment.However,few investigations on the progress of COFs in solid phase microextraction(SPME)are available.In this paper,the preparation methods of COFs coated fibers,extraction mechanism and their applications in the enrichment and analysis for various organic pollutants were reviewed in the past five years,and the development trend of COFs was also prospected.
