In
this study, the synthesis, electrochemical and spectroelectrochemical
properties of new peripherally 1,2,4-triazole substituted metal-free 4, Zn(II) 5, Ti(IV) 6, Ni(II) 7 and Co(II) 8 phthalocyanine derivatives were reported. Voltammetric and in situ spectroelectrochemical
characterization of the complexes were performed in solution. Since nickel and
zinc phthalocyanines gave common phthalocyanine ring based electron transfer
reactions with the characteristic “energy gaps”, “peak to peak potential separations”
and “half wave peak potential values”, CoII and TiIVO
metal ions behaved as redox active cations in the core of the cobalt and
titanium phthalocyanine complexes, respectively. While cobalt phthalocyanine
gave a one-electron [CoIIPc-2]/[CoIPc-2]-1
reduction reaction, titanium phthalocyanine illustrated two metal based
reduction reactions, [TiIVOPc-2]/[TiIIIOPc-2]-1
and [TiIIIOPc-2]-1/[TiIIIOPc-2]-2,
in addition to the Pc ligand reduction processes. Electron transfer reactions
altered the spectra of the complexes considerably, which is one of the most
important expectations for the practical applications of the complexes
especially in display technologies. Redox and spectral responses of cobalt and
titan complexes were affected by the molecular oxygen present in the
electrolyte, which indicates electrocatalytic and electrosensing activity of
the complexes towards the molecular oxygen.
