Electropolymerization of magnesium 5,15-di(n-methoxyphenyl)porphine

International audienceThe process of electroxidative polymerization of magnesium 5,15-di(N-methoxyphenyl)porphine MgP(MeOPh)(2) is studied. The presence of substituents in positions 5 and 15 of the porphine macroring makes reactive two of its four meso positions, which allows new bonds to be formed only in the opposite positions 10 and 20. As a result, the process of electropolymerization of this substituted monomer at its oxidation can produce only linear chains, in contrast to unsubstituted magnesium porphine MgP for which the polymer structure can both be linear and contain zigzag and/or cruciform fragments
