Heteroassociation of cationic cyanines (quinaldine red, quinaldine blue) with 3',3'',5',5''-tetrabromo-m-cresolsulfonephthalein anions has been studied experimentally and theoretically. The values of the equilibrium association constants in the aqueous solution are determined spectrophotometrically. Geometric and energy characteristics of associates are calculated with the help of AM1 method. The effect of ionic surfactants on associates has been studied.
