摘　　要：固定化离子液体是将离子液体通过物理吸附或化学键合等方法与固载材料结合而成,不仅保持了离子液体稳定性好、挥发性低、结构可优化等特点,还提高了离子液体的催化活性和重复利用性。固定化离子液体广泛应用于缩合、偶联及不对称合成等反应中。本文介绍了固定化离子液体的制备、固载材料的分类、结合方式及固定化离子液体在有机合成中的应用进展。The immobilized ionic liquid is the combination of the ionic liquid and support material,in which two distinct parts are connected by two different interaction forces,one is the physisorption of ionic liquids to the supporting surface,such as Vander Waals,hydrogen bonding etc,and the other is chemisorption of the ionic liquids to the surface,such as covalent bonding. The immobilized ionic liquid remains the main advantages of ionic liquid,and has higher catalytic activity and better reusability. This novel catalyst can be used in many organic reactions,such as condensation reaction,coupled reaction and asymmetric synthesis. This article describes the variety of immobilized materials, interaction forces between support material and ionic liquid, and the applications of immobilized ionic liquids in organic synthesis as catalyst.
