金属-有机骨架材料(Metal-organic frameworks,MOFs),因其具有较好的热稳定性、化学稳定性、可设计性等特点,广泛应用于气体吸附、物质分离、提纯、催化等领域,同时也作为模板制备各种功能材料.MOFs作为色谱分离的材料已得到了较多的研究与应用.按照被分离物质的类别,综述和总结了不同MOFs材料作为色谱固定相的分离效果,重点介绍了MOFs材料的色谱分离机理.MOFs材料的孔径、功能基团和不饱和金属位点在分离中起到重要的作用,最后对MOFs在色谱分离应用中的问题和前景进行了分析和展望.
Metal-organic frameworks (MOFs) are widely used in the fields of gas adsorption, material separation, purification and catalysis because of their good thermal stability, chemical stability and designability. Meanwhile, But also as a template for the preparation of a variety of functional materials.MOFs as chromatographic materials have been more research and application.According to the type of material was isolated, reviewed and summarized the separation of different MOFs material as a chromatographic stationary phase separation, focusing on The mechanism of chromatographic separation of MOFs is discussed.The pore size, functional group and unsaturated metal sites of MOFs play an important role in the separation.Finally, the problems and prospects of MOFs in chromatographic separation are analyzed and prospected.
