中文摘要：

共价有机框架材料（covalent organic frameworks,COF）是功能材料领域研究的热点之一。COF具有孔道结构高度有序、孔径可调、比表面积较大、合成方法多样和易于功能化修饰等优点,是一类新兴的多相催化剂。目前,COF催化剂主要设计思路是：基于＂自下而上＂策略将非金属催化活性中心嵌入材料骨架来构筑本征型COF催化剂,或者以COF为载体,通过后修饰方式负载金属颗粒或离子构建多相催化剂。鉴于COF以上优势,预计COF催化剂在多相催化和手性催化领域中的应用也将取得更大的进展。本文综述了COF催化剂的合成和功能化策略,并展望了COF在多相催化领域中的应用前景。

英文摘要：

Covalent organic frameworks （COF） arise as the new frontier among the enormous research efforts in functional materials. Due to their well-defined channel structure, tunable porosity, larger surface area, vast synthetic diversity and facile functionalization at the molecular level, COF has emerged as a matrix for heterogeneous catalysts. Such catalysts are generally constructed via the ＂bottom-up＂ strategies from building blocks. Utilizing a simple post- modification strategy, COF catalysts are prepared by loading metal particles or ions into the pores or interfaces. Benefiting from its structural su.periority, COF catalysts with excellent catalytic activity will also make a great achievement. Here, this review focuses on recent advances of COF-functional catalysts, by briefly summarizing their synthetic strategies, targeted functionalization, and their perspectives in heterogeneous catalysis.
