共价有机框架材料研究进展

摘要

共价有机框架材料是一类具有周期性和结晶性的有机多孔聚合物.共价有机框架材料由轻质元素通过共价键连接,拥有较低的密度、高的热稳定性以及固有的多孔性,在气体吸附、非均相催化、能量存储等研究领域有着广泛的应用潜力,引起了科学界强烈的研究兴趣.本文主要综述了近年来共价有机框架材料的最新研究进展,包括其结构设计、合成、纯化、表征以及在气体吸附,催化及光电等方面的应用,并对共价有机框架材料未来的发展趋势进行了展望.%Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers,constructed with lightweight elements by covalent bonds.Owing to their low density,high thermal stability,and inherent porosity,COFs have many potential applications in gas adsorption,heterogeneous catalysis,energy storage,etc.This article reviews the latest progress in COFs,including their structural design,synthesis,purification,characterization methods,and applications in gas adsorption,catalysis,and photoelectricity.Finally,the prospects of COFs are also discussed.
