The phthalocyanines and porphyrins enjoy a growing importance as potential photo and electrocatalysts for energy conversion processes as they are highly colored, exhibit diverse redox activity, and are relatively photochemically stable.The electrochemistry and spectroelectrochemistry on 2,3,9,10,16,17,23,24-octabutylchloromethylsiliconphthalocyanine(1) is investigated and correlated with theoretical calculations. Compound (1) undergoes two one electron reductions and two one electron oxidations. The two one electron reductions and the first oxidation are reversible where as the second one electron oxidation is irreversible. Spectral changes during the oxidation and reduction processes are due to the Π*-Π* and Π-Π* transitions.
