摘　　要：功能化离子液体是将功能团引入到离子液体的阳离子或阴离子上,从而赋予离子液体某种特殊性质.将具有催化活性的基团引入到离子液体的阳离子或阴离子上所得到的功能化离子液体,是一类新型的催化材料.除了具有优异的催化性能,其特殊的物理化学性质很容易实现产物与催化剂的分离,正在许多重要催化过程中发挥作用.本文主要介绍近年来我们关于功能化离子液体的制备、性质及其在催化反应中的应用等研究,同时指出了目前存在的问题,并对今后发展趋势进行了展望.Task-specific ionic liquids （TSILs） can be defined as liquid salts in which functional group is covalently tethered to the cation or anion （or both） of the salts. By incorporating a catalytic active group on the cation or anion, a new type of ionic liquid catalytic material could be obtained. Due to their novel physieochemical properties and facile separation and recycling, TSILs are regarded as powerful catalysts for a variety of important catalytic processes. The present review focuses on our recent progresses in the field of TSILs with particular emphasis on their applications in catalysis. The existing problems and the developing direction of the further research are also put forwarded.
