摘　　要：二维共价有机框架材料(2D-COFs),作为一类由轻质元素通过共价键的方式连接而成的新型结晶型多孔材料,其拥有规则有序的孔道、较大的比表面积、良好的稳定性及延展的π共轭体系,已被证实具有良好的光化学活性及实现光致化学转化的潜力。因此,二维共价有机框架材料作为非均相光催化剂实现光致化学转化已经成为多孔材料领域及光催化领域的一个新的研究热点。本文总结了近年来2D-COFs作为光催化剂在光致化学转化领域的最新研究进展,并对未来进行了展望。Two-dimensional Covalent organic frameworks(2D-COFs),as a new type of crystalline porous materials constructed with organic building blocks,possessing regular pore structure,good stability,high surface area and extendedπ-conjugation system,have shown good photoactivity and tremendous potential for lightdriven chemical transformations.Therefore,the application of 2D-COFs in light-driven chemical transformations has recently garnered great attention in both porous materials science and photocatalysis.This review mainly summarizes and discusses the applications of photoactive 2D-COFs in light-driven chemical transformations in recent years.Future development is also prospected.
