Synthesis and electrochemistry of new thienyl - Schiff base complexes
The synthesis and characterization of nickel(II), copper(II), and vanadyl ([V=O] 2+ ) complexes of two new thienyl-substituted Schiff base ligands are reported. Cyclic voltammetry of some of these complexes showed oxidation waves, but none of the complexes formed conductive polymer films upon repeat...

) complexes of two new thienyl-substituted Schiff base ligands are reported. Cyclic voltammetry of some of these complexes showed oxidation waves, but none of the complexes formed conductive polymer films upon repeated cycling. UV-vis absorption spectroscopy shows that some of the complexes exhibit enhanced conjugation, and the radical cations formed on these chromophores appear to be too stable to undergo oxidative coupling.Key words: Schiff base, salphen, conjugated polymer, electrochemistry. |
