Electrosynthesis and electrochemical properties of porphyrin dimers with pyridinium as bridging spacer

Résumé

Two porphyrin dimers (more precisely two isomers) with pyridinium as bridging spacer have been obtained by controlled potential electrolysis. This method is based on a nucleophilic substitution of a porphyrin substituted by a pyridyl group (namely 5,10,15-tritolyl-20-(4-pyridyl) porphyrin (H(2)T(3)P-4-Py) or 5,10,15-tritolyl-20-(3-pyridyl) porphyrin (H(2)T(3)P-3-Py)) on an electrogenerated radical cation of a zinc beta-octaethylporphyrin (ZnOEP). The new compounds have been characterized by HR-MS, (1)H NMR, UV-vis and fluorescence spectroscopies. Difference of electrochemical behaviour of the pyridinium spacers between the two dimers has been also discussed.
