Synthesis of Covalent Organic Framework Materials and Its Research Progress in the Field of Adsorption

共价有机框架(COFs)材料是由有机小分子单体通过共价键连接而形成的多孔结晶聚合物。COFs集成了多孔性、有序性、高比表面积、低密度和功能可调性于一身,在吸附领域表现出优异的应用前景。COFs常用的合成方法还局限于实验室阶段,对COFs材料的合成方法和合成条件还有待进一步探索。通过比较不同种类的COFs材料对气体、重金属和有机物的吸附性能,阐述了提高吸附容量的方法、吸附机制等。综述了几种典型的COFs合成策略及其在吸附领域的研究进展,从不同角度展望了COFs材料未来的主要研究方向和应用前景。

Covalent Organic Frameworks(COFs)are porous crystalline polymers formed by covalent bonding of small organic molecule monomer.COFs integrate porosity,orderliness,high specific surface area,low density and functional adjustability,showing excellent application prospects in the field of adsorption.The commonly used synthesis of COFs is still limited to the laboratory stage,and the synthesis methods and synthesis conditions of COFs materials need to be further explored.By comparing the adsorption properties of different types of COFs materials for gas,heavy metals and organic matter,the methods and adsorption mechanisms for improving the adsorption capacity are described.Several typical COFs synthesis strategies and their research progress in the field of adsorption are reviewed.The main research directions and application prospects of COFs materials in the future are prospected from different perspectives.
