摘要:离子液体是一种由阴离子和阳离子共同组成的有机熔融盐,其挥发性低、热稳定性和化学稳定性好、电
化学窗口宽、结构可调变,近年来在诸多领域具有广泛的应用。但因其黏度大不便于输送和操作,合成成本较
高、回收利用率低等缺点,离子液体发展受到了一定的限制。金属有机骨架(MOFs)材料是由金属阳离子/团
簇和有机配体通过配位键自组装形成的具有分子内孔隙结构的有机-无机杂化材料。以 MOFs 为载体固载离子液
体,不仅可以保留离子液体的优势,还可以赋予离子液体很多新的特性。该文从 MOFs 固载离子液体的理论计
算和实验应用研究出发,综述了 MOFs 固载离子液体的起源和固载方式,分析了 MOFs 和离子液体之间的兼容
性、固载形式和相互作用,并对 MOFs 固载离子液体的瓶颈问题进行了分析,对未来发展方向进行了展望。

Abstract: Ionic liquids, organic molten salts composed of both anions and cations, have been widely used
in many fields in recent years due to their low volatility, good thermal and chemical stability, wide
electrochemical window, and adjustable structure. However, the development of ionic liquids has been
limited owing to their high synthetic cost, high viscosity, inconvenient transport and operation, and low
recyclability. Metal-organic frameworks (MOFs) are organic-inorganic hybrid materials with intra-
molecular pore structures formed by the self-assembly of metal ions or clusters and organic ligands through
coordination bonds. Composites formed by immobilization of ionic liquids on MOFs carriers can overcome
the disadvantages of ionic liquids and endow the ionic liquids with many new properties as well. Herein, on
the basis of computational research and experimental application progress of MOFs immobilized ionic
liquids, the origin and immobilization methods were summarized, and the compatibility, immobilization
forms and interactions between MOFs and ionic liquids were analyzed. Finally, the bottlenecks and the
future development directions of MOFs immobilized ionic liquids were discussed.
Key words: ionic liquids; metal-organic frameworks; immobilization; catalysis; supported catalysts
