Abstract:

Covalent organic frameworks (COFs) that are composed of organic building blocks connected with reversible covalent bonds are a type of newly emerging porous materials with high crystallization and well-defined periodicity. As a result of their large surface areas, low density, versatile tunable structures, excellent thermal stability, and easily modified channels, COFs have received increasing attention in recent years. This review summarized the research advances on COFs in the past decade by classifying them based on the substrate materials. The application and development of COFs were introduced, such as energy storage, photoelectricity, catalysis and biomedicine, including gas adsorption and storage, the photoconductivity of materials, the performance of catalytic reactions, the chiral separation and sustained-controlled release of drugs, etc. The characterization of COFs structure and the superior feature compared with other materials were discussed. The paper points out that the future development trend of COFs is to synthesize functional materials with high stability, controllable structure and low cost. Finally, the practical application prospects of COFs will be given.

Key words: covalent organic frameworks, porous material, properties

摘要:

共价有机框架材料(covalent organic frameworks,COFs)是一类新兴的材料,是一种由有机构筑基元构成并用可逆的共价键进行连接、具有结晶性和周期性的多孔材料。因为这种材料比表面积大、密度低,拥有多样性的结构、优秀的热稳定性及孔道易修饰等优点,越来越受到人们的关注。本文综述了近年来COFs的最新发展动态,将其按照基底材料不同进行分类,介绍COFs在储能、光电、催化、生物医药等方面的应用和发展,包括气体的吸附和存储、材料的光电导性、催化反应进行的性能、手性分离和药物缓控释等;讨论了COFs结构的表征以及相比于其他材料所具有的优越特性。最后指出COFs未来发展趋势是合成具有高度稳定性、结构可控、成本低廉的功能性材料,并对其在实际中的应用前景进行展望。
