Investigations on the hydrophobic and ionophoric character of para-(5-phthalhydrazide-azo)-phenylene-N-aza-15-crown- (1) were carried out by reversed phase thin layer chromatography (RP-TLC) and spectrophotometric measurements. The study included complexes with Li+ and Na+ cations (as perchlorates in acetonitrile and as dibenzyldithiocarbamate salts in chloroform). In both cases, the stoichiometry of complexes was 1:1:1 (1:M+:anion pair). The complex stability (logKS ) is similar.
