摘要
螯合型离子液体(chelate-based ionic liquids, Ch ILs)是一类可以在低温(<100℃)或室温下熔化的金属螯合物,近年来已被成功应用于催化、气体吸收等领域.螯合型离子液体不仅丰富了离子液体的种类而且扩展了其应用范围,然而,关于此类离子液体结构和物性的研究仍较为缺乏.本文对课题组近期在醇胺型和六氟乙酰丙酮型两类螯合型离子液体在结构与物性方面取得的研究进展进行了评述,主要包括:(1)螯合型离子液体及其与分子溶剂混合体系的宏观物性;(2)结合单晶数据和量化计算研究螯合型离子液体的结构;(3)螯合型离子液体与分子溶剂间的相互作用.通过实验和理论的方法建立起了对螯合型离子液体从微观到宏观的系统研究方法,为设计新型功能型离子液体和拓展其应用范围提供思路和参考.
Chelate-based ionic liquids(ChILs) are a type of chelating compound which can melt at low temperature(<100 ℃). ChILs have been successfully used in catalysis, gas capture and other fields, which enrich the types of ILs and expand their application range. However, researches on the structure and physical properties of ChILs are still lacking. Our group carried out a series of researches which can be divided into three parts:(1) physicochemical properties of pure ChILs and their mixtures with molecular solvents;(2) structural and electronic properties by quantitative calculation combined with single crystals;(3) the interactions between ChILs and molecular solvents. By means of experiments and quantum chemistry, systematic research for ChILs from micro to macro has been established,which will shed light on rational design and practical applications.
