Summary.
Some porphyrazines with dimethylamino- or trimethylammoniumethylsulfanyl substituents were studied in dichloromethane or dimethylsulfoxide solution by cyclic voltammetric methods. The cyclic voltammogram of metal free octakis-(dimethyl-aminoethylsulfanyl)-porphyrazine is characterized by three one-electron reduction waves which show quasi-reversible behaviour at all sweep rates observed; the same holds for its cobalt(II) derivative. The quaternized octacationic derivative, however, exhibits four one-electron reduction waves which are reversible at all sweep rates. The reaction mechanisms and diffusion coefficients were investigated.
