    • Abstract

       

      A few 1,8-naphthalimide derivatives with phenyl (1), benzyl (2), 3,4-dimethoxyphenyl ethyl (3), 4-pyridyl (4), 2-hydroxy ethyl (5), 4-pyridylmethyl (6) groups attached to the nitrogen atom are synthesized and characterized. Cyclic voltammograms of all these compounds show one-electron reversible redox cycle ( −1·24 V to −1·18 V) due to formation of anion radicals. However, in the case of (5), quenching of this redox process occurs when polyhydroxy-aromatic compounds such as 1,3-dihydroxy benzene and 1,3,5-trihydroxybenzene are added. Copper complexes, namely bis-{N-(4-pyridylmethyl)1,8-naphthalimide} copper (II) perchlorate (8), bis-{N-(4-pyridylmethyl)1,8-naphthalimide}copper (II) perchlorate (9) and bis-{N-(4-pyridylmethyl)phthalimide} copper (II) perchlorate (10) are synthesized and characterised. The complexes (8) and (9) show reversible redox couple of the ligand without any significant interaction with the redox active copper (II) centre.
