摘要:

热力学实验、理论计算以及计算机模拟是离子液体微观结构与相互作用研究中常用的三种手段, 但是目前采用这些手段对离子液体结构的认识尚处于初步探索阶段, 还没有完全找到离子液体性质随结构变化的规律, 尚未完全能够对离子液体进行“设计”, 这也使得对离子液体的进一步开发和应用受到极大的限制. 近年来,谱学方法成为研究溶液结构的重要手段. 其中, 红外光谱(IR)和拉曼光谱(Raman)等谱学手段在离子液体的结构与相互作用研究中发挥着越来越重要的作用.本文着重概述了红外光谱和拉曼光谱在纯离子液体及离子液体混合溶液结构与相互作用方面的研究进展、挑战以及发展方向.

Abstract:

Experimental methods, theoretical calculations as well as computer simulations are the three most often used approaches to investigate the microscopic properties and interactions of ionic liquids (ILs). The relationship between the structure and properties of ILs, which is the foundation for designing new functional ionic liquids and promoting their applications in cleaner production, are not thoroughly understood. Recently, spectroscopic methods have been developed to study the structures of solutions. Among the various spectroscopic methods, infrared spectroscopy and Raman spectroscopy play important roles in investigations on the structural properties and interactions of ionic liquids. We thus review the applications and progress of these two spectroscopic methods on structural and property studies of pure ionic liquids and ionic liquids/solvent mixtures. Additionally, we address the associated challenges and prospects.
