The electrochemistry and spectroelectrochemistry of mononuclear, binuclear and tetranuclear zinc neopentoxy-substituted phthalocyanines are presented. The binuclear and tetranuclear species show two oxidation waves to the radical cation indicating the existence of stable mixed valence, half-oxidized species. The electronic spectra of the half- and fully oxidized species are presented and discussed. Nernstian analysis shows that pairs of phthalocyanine oxidation pathway. Keywords Phthalocyanine, Electrochemistry, Mixed valence, Spectro-electrochemistry.
