The electrochemical synthesis of linear symmetrical octaethylporphyrin-octaethylporphyrin and unsymmetrical tetraphenylporphyrin-octaethylporphyrin dimeric porphyrins with one viologen as a spacer and of their precursor porphyrin monomers is reported. The mechanism of the electrochemical substitution leading to the dimeric porphyrins is discussed. These new compounds have been characterized by 1H NMR, UV-vis spectroscopy, FAB mass spectroscopy, and microanalysis. Electrochemical data are reported, and the redox behavior is analyzed for the monomers and the dimers in terms of π-π interactions between the two porphyrin centers. ESR measurements were carried out on the unsymmetrical Cu-Zn and Cu-Cu dimeric metalloporphyrins which displayed intermolecular metal interactions.
