Abstract

Ionic liquids (ILs) have attracted intensive attention and have been used widely in many applications because of their diversified properties, which are caused by the special structure of the ILs. Ionic clusters are one of the typical structures that exist widely in the IL system. They are stable under certain conditions and change under other conditions. Ionic clusters are a typical mesoscale phenomenon in mesoscience. In this review, we summarize our recent progress related to ionic clusters, including the ionic-cluster structure, changing mechanisms, and their effect on the physicochemical properties. IL cluster investigation based on mesoscience is very important, will provide new insight into the structures and properties of ILs, and will boost further exploration of IL applications.
