Ionic liquids are organic molten salts composed of both anions and cations. They possess low volatility, good thermal and chemical stability, wide electrochemical window, and adjustable structure, which are widely used in many fields in recent years. However, owing to the high synthetic cost, high viscosity, inconvenient transport and operation, and low recyclability, the development has been limited to a certain extent. 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. The ionic liquids are immobilized on MOFs carriers to form composites which not only could solve the disadvantages of ionic liquids, but also endow the ionic liquids with many new properties. In this paper, we review the origin and immobilization methods of MOFs immobilized ionic liquids, and analyze the compatibility, immobilization forms, and interactions between MOFs and ionic liquids, based on the computational research and experimental application progress of MOFs immobilized ionic liquids. Finally, we discuss the bottlenecks of MOFs immobilized ionic liquids and provide an outlook on the development direction.
