The lipophilicity of ten ruthenium(II)-arene complexes was assessed by reversed-phase thin-layer chromatography (RP-TLC) on octadecyl silica stationary phase. The binary solvent systems composed of water and acetonitrile were used as mobile phase in order to determine chromatographic descriptors for lipophilicity estimation. Octanol-water partition coefficient,logKOW, of tested complexes was experimentally determined using twenty-eight standard solutes which were analyzed under the same chromatographic conditions as target substances. In addition,ab initiodensity functional theory (DFT) computational approach was employed to calculatelogKOWvalues from the differences in Gibbs’ free solvation energies of the solute transfer fromn-octanol to water. A good overall agreement between DFT calculated and experimentally determinedlogKOWvalues was established (R2= 0.8024–0.9658).

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.
