The electrochemical behavior of tetra-4-[4-(2,4,5-trichlorophenoxy)]phthalocyaninates of cobalt(II) (CoPc) and copper(II) (CuPc) in N,N-dimethylformamide 0.1 M nBu4NBF4 was studied by cyclic voltammetry. It has been experimentally established that both metal complexes are capable of irreversible reduction. In the reverse part of the CV curve for CoPc, an oxidation peak is observed, which is absent during anodic scanning, and corresponds to the cathodic reaction product. The metal complexes themselves do not oxidize under the conditions.
