摘要
金属有机骨架材料(MOFs)是利用金属离子或金属离子簇形成的次级结构单元与含氮、羧酸类官能团的有机配体通过自组装形成的具有晶体结构的多孔材料,与传统多孔材料相比,其拥有极高的比表面积和孔隙率,且孔道结构可调,因此具有良好的吸附和检测性能。本文通过介绍近年来金属有机骨架材料在吸附碘分子、吸附有机染料、检测金属汞离子、检测有机溶剂分子、吸附与分离气体以及检测生物标志物等方面的应用,分析吸附检测的机理,总结金属有机骨架材料的设计理念,为金属有机骨架材料的设计和吸附检测性能开发提供了新思路。
Metal-organic framework materials(MOFs)are porous materials with a crystal structure formed by selfassembly of secondary or structural units of metal ions and organic ligands containing nitrogen and carboxylic acid functional groups,and metal organic framework materials.Compared with traditional porous materials,MOFs have extremely high specific surface area and porosity,and the pore structure is adjustable.Therefore,MOFs possess good adsorption and detection performance.MOFs in molecular iodine adsorption,the adsorption of organic dyes,detecting mercury metal ions,organic solvent molecules and the application of gas adsorption and separation in recent yearswas introduced,the mechanism of adsorption test was analyzed,the design concept of metal organic skeleton materials was summarized,providing a new way of thinking for the adsorption of metal-organic framework materials design and detection performance development.
