- Abstract
Twelve structurally related pyridyl and meso- N-methylpyridylporphyrin derivatives are investigated electrochemically in different nonaqueous media. The UV/Vis spectrum of each newly investigated porphyrin was measured before and after electroreduction and, based on this data, the site of electron transfer is proposed. An interaction occurs between the meso-pyridyl or meso- N-alkyl-4-pyridyl substituents and the porphyrin π-ring system, the magnitude of which depends upon the number of linked pyridyl or N-alkyl-4-pyridyl groups in the compound, the solvent, the supporting electrolyte, and/or other anions added to the solution.
