双阳离子型离子液体的研究进展

Research progress of dicationic ionic liquids

对双阳离子型离子液体的合成路线及其密度、熔点/玻璃化温度、热稳定性、表面张力和黏度等物理化学性质与结构之间的关系进行了综述.目前双阳离子型离子液体的研究主要集中在各种新型离子液体合成和物化性能研究,而其体系的热力学性质及量化计算和分子模拟等方面的研究还比较缺乏.今后应着力于确定双阳离子型离子液体结构与性能间的构效关系以及建立相应的模型.

The synthesis methods of dicationic ionic liquids and the relationship between their structures and physicochemical properties including density, melting point/glass transition temperature, thermostability, surface tension and viscosity were reviewed. Nowadays, the dicationic ionic liquids research are focused on synthesis of new species and physicochemical properties. The investigation on dicationic ionic liquids is quite self-evident in the scarcity of the thermodynamic properties, the quantitative calculation and molecular simulation. In the future, the attention for dicationic ionic liquids will be determining the structure-activity relationship and the corresponding model building.
