摘　　要：吸附分离过程具有高效率、低能耗等特点,广泛用于石油、化工、制药、环保等诸多领域。其中,吸附分离材料的结构特点(如比表面积、孔径、孔体积、表面官能团等)对吸附分离效果起决定性作用。金属有机骨架(MOF)材料具有优异的孔结构特点,同时其表面还具有丰富的官能团(—NH2、—CHO等),易于后修饰功能化并赋予其特定的功能,从而增强MOF材料与吸附质之间的相互作用,实现较高的吸附容量和分离选择性。以此为导向,本文首先概括了氨/醛基MOF材料的合成策略,总结了亚胺共价后修饰MOF (ICPSM-MOF)材料的研究进展,并重点介绍了这类材料在气、液相吸附分离领域的应用,最后分析了当前ICPSM-MOF材料面临的困难与挑战,并对其未来研究方向进行了展望。Adsorptive separation has been widely used in petroleum, chemical, pharmaceutical, environmental protection and many other fields due to the advantages of high efficiency and low-energy consumption. Therein, the structural characteristics(such as specific surface area, pore size, pore volume, surface functional groups, etc.) of the adsorbent are the key factors that affect the adsorption capacity and separation efficiency. Metal-organic framework(MOF) materials have excellent pore structures and abundant functional groups(—NH, —CHO, etc.), which can be easily post-modified and functionalized with specific functions, thus enhancing the interaction between MOFs and adsorbates and achieving high adsorption capacity and separation selectivity. In this context, the synthesis strategies of MOF-NH/CHO materials were firstly outlined, then the research progress of imine covalently post-modified MOF(ICPSM-MOF) materials was summarized, and their applications in gas and liquid adsorption separation were emphasized. In addition, the difficulties and challenges faced by the current ICPSM-MOFs were finally analyzed, and the future research trend of ICPSM-MOFs was also put forward.
