ChitoCin and ChitoThioCin polymer ligands were synthesized by the reaction of chitosan with cinnamoyI chloride and / or cinnamoyI isothiocyanate. ChitoCin acts as monobasic monodentate ligand which coordinates through oxygen site of the NH-C=O moiety of each monomer unit while ChitoThioCin acts as monobasie bidentate polymer ligand which coordinates through oxygen and sulfur sites of the NH-CO-NH-C=S moiety
