Octabutoxyphthalocyanine, a new electron donor

Abstract

The preparation of the 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine zinc complex (1) is described. The electron-donating groups influence the properties of the compound. The oxidation–reduction potentials studied by cyclic voltammetry in solution shift by ca. 20 mV in the cathodic direction showing easier oxidation and harder reduction of the ligand of (1) compared to unsubstituted phthalocyanines. The interaction with iodine results in the formation of iodine complexes. The electrical conductivities are mentioned.
