Comparative behaviour of the anodic oxidation of mono-, di- and tetra-arylporphyrins: Towards new electroactive materials with variable bandgaps

Electrochemical behavior of the tetracationic porphyrins and

“…Many examples of porphyrin electropolymerizations were reported in the literature. The corresponding radical coupling process occurred usually via electro-oxydation [14,15,[55][56][57][58]. Processes via electro-reduction, as the presented one, were less frequent.…”

Magnesium(II) polyporphine: The first electron-conducting polymer with directly linked unsubstituted porphyrin units obtained by electrooxidation at a very low potential

“…They have been obtained by electrochemical oxidation of the corresponding monomer [7][8][9] or by chemical synthesis [10,11].…”

A simple way for the electropolymerization of porphyrins

“…The other most common strategy in porphyrins polymerization, which was widely developed since the studies of Macor and Spiro [5], consists in the oxidative radical coupling of the porphyrins via substituents on the ring periphery [6][7][8]. Thus the starting porphyrin subunit should bear oxidizable substituents.…”
