“…Ionic selectors have been widely used as the stationary phase or additive of mobile phase in chromatography (HPLC [54][55][56][57][58][59][60][61], counter-current chromatography [62][63][64][65], CE [66][67][68][69][70][71], and GC [72][73][74][75][76][77][78][79][80]), leading to high recognition efficiency. When the ionic cyclodextrin was synthesized and applied as the stationary phase, its separation efficiency can be up to 10 times higher than the traditional materials [77].…”

Ionic chiral selectors have been received much attention in the field of asymmetric catalysis, chiral recognition, and preparative separation. It has been shown that the addition of ionic chiral selectors can enhance the recognition efficiency dramatically due to the presence of multiple intermolecular interactions, including hydrogen bond, π-π interaction, van der Waals force, electrostatic ion-pairing interaction, and ionic-hydrogen bond. In the initial research stage of the ionic chiral selectors, most of work center on the application in chromatographic separation (capillary electrophoresis, high-performance liquid chromatography, and gas chromatography). Differently, more and more attention has been paid on the spectroscopy (nuclear magnetic resonance, fluorescence, ultraviolet and visible absorption spectrum, and circular dichroism spectrum) and electrochemistry in recent years. In this tutorial review as regards the ionic chiral selectors, we discuss in detail the structural features, properties, and their application in chromatography, spectroscopy, and electrochemistry.
