Complex formation equilibrium of phenylalkylammonium ions (PAA+) with 18-crown-6 (18C6) has been analyzed by capillary zone electrophoresis (CZE). The electrophoretic mobility of PAA+ (μep') was measured by CZE in the presence of 18C6 in a migrating buffer, and the μep' values were used for equilibrium analysis. The μep' values decreased with increasing concentrations of 18C6, and 1 : 1 complex formation constants, K, were determined. The K values for PAA+ in an aqueous solution are comparable to literature data reported for the ammonium ion. The K values increased with a longer alkyl chain in PAA+, except for the benzylammonium ion. The results suggested the contribution of hydrophobicity in PAA+, as well as CH/π interactions for the benzylammonium ion. The K values also increased in mixed aqueous solvents with a decreased dielectric constant, which suggested the contribution of ion-dipole interaction in the complex formation reaction.
