Sažetak
Syntheses and properties of complexes of dibenzo-24-crown-8 with the sodium monoethyl ester and the sodium monobutyl ester of [α-(4-benzeneazoanilino)-N-benzyl]phosphonic acid, [α-(4-benzeneazoanilino)-N-4-hydroxybenzyl]phosphonic acid and [α-(4-benzeneazoanilino)-N-4-methoxybenzyl]phosphonic acid have been studied. The crystalline complexes formed were found to depend not only on the size of the cation and the crown ether cavity but also on the choice of anion and the reaction solvent. It was shown that the molecular structure and electronic configuration of the anion are important factors in a salt-ligand system which influence the case of solubilization and charge separation in solution. The complexes obtained were characterized on the basis of conductance measurements and UV, IR and 1H NMR spectra.
