    Affinity capillary electrophoresis (ACE) and quantum mechanical density functional theory (DFT) calculations were combined to investigate non-covalent binding interactions between the hexaarylbenzene-based receptor (R) and alkali metal ions, Rb+ and Cs+, in methanol. The apparent binding constants (Kb) of the complexes of receptor R with alkali metal ions in the methanolic medium were determined by ACE from the dependence of effective electrophoretic mobility of the receptor R on the concentration of Rb+ and Cs+ ions in the background electrolyte. The structural characteristics of the above alkali metal ion complexes with the receptor R were described by ab initio DFT calculations.
