The differences of chemical shift values of o ‐ and p ‐methyl signals in the 1 H‐NMR spectra of Zn, Ni, Pd, and Pt complexes of tetramesitylporphyrin (Δδ = 0.785–0.755 ppm) are not significantly different from that of the free ligand (Δδ = 0.771 ppm) indicating the same order of delocalization of π electrons in the outer annulene sphere of the porphyrin ring.
