5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladiminato]copper(II) [alkoxy=OnCnH2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and IR spectra. All complex homologues are thermally stable. Cyclic voltammetric studies indicated that all copper complex homologues have a quasi-reversible redox wave and peak current ratio (ipa/ipc)decreasing with increase of alkyl chain length.
