N-methyl fused nickel(II) porphyrin was synthesized by a facile synthetic route in excellent yield. The effect of the electron-donating methyl group on spectral and electrochemical redox properties was analyzed by comparing the electrochemistry with that of its precursors. N-methylated fused nickel(II) porphyrin exhibited a red-shifted absorption spectrum (δλmax = 6-13 nm) and a 180mV anodic shift in the first ring oxidation as well as a 210mV shift in reduction with respect to its Ni(II)-fused porphyrin precursor (NiII-(NH)TPP). However, the absorption spectral features and redox potentials of N-methyl fused nickel(II) porphyrin are marginally shifted as compared to its immediate precursor, β-formyl Ni(II)-fused porphyrin. Notably, Ni(II)(N-CH3)(CHO)TPP exhibited a third oxidation at 1.51mV, corresponding to oxidation of Ni(II) to Ni(III) due to the presence of push-pull β substituents.

A doubly fused porphyrin has been synthesized by two successive cyclization reactions. The first meso-phenyl group was fused, by an intramolecular Cadogan reaction leading to an enamine-functionalized porphyrin. After Vilsmeier-Haack formylation of the ni
