共价有机骨架材料应用研究进展

Progress on the covalent organic frameworks and the application

共价有机骨架(COFs)材料是一种多孔晶态聚合物材料,大致可分为四类:含硼类COFs材料、亚胺类COFs材料、三嗪类COFs材料和其他类COFs材料.与传统无机多孔材料相比,COFs材料具有较高的热稳定性、极低的密度、较大的比表面积、良好的结构裁剪性等显著的优势.在气体吸附、光电、催化、传感等方面应用广泛.除要设计开发新的前体、新的合成方法以及新的连接方式来实现理论与实验的完美结合外,通过加入特定的砌块,赋予材料更广泛的应用性能,将是COFs复合材料未来的发展方向.

Covalent organic frameworks（ COFs） is an emerging type of crystalline porous material,which includes four types-boron type,imine type,triazine type and other type. In comparison with traditional amorphous porous materials,COFs shows exceptional thermal stability,low density,high specific surface area and flexible structure modification,which made it have wide potential application in gas adsorption,photoelectricity,catalysis and biosensor. In addition to designing and developing new precursor,new synthetic methods and new ways of connection to achieve the perfect combination of theory and experiment,the addition of a specific block to give the material a wider range of application performance will be the development direction of the COFs composite materials in the future.
