- Abstract
A new series of β‐heptasubstituted porphyrins MTPP(NO2)(Me)6 (M = 2H, CoII, NiII, CuII, and ZnII) was synthesized and characterized by various spectroscopic techniques. The single‐crystal X‐ray structure analysis of CoTPP(NO2)(Me)6 revealed the significant saddle distortion of the macrocyclic core from the porphyrin mean plane (ΔCβ = 0.928 Å). These porphyrins exhibit significant redshifted electronic spectral features (Δλmax = 40–62 nm) as compared with MTPP due to the combined effect of the nonplanar conformation of the macrocyclic core and mixed β‐substituents. H2TPP(NO2)(Me)6 has shown a high dipole moment (7.12 D) as compared with H2TPP (0.052 D) due to cross‐polarized push–pull substituents. The redox tunability was achieved by appending the electron‐donating methyl and electron‐withdrawing NO2 group at the β‐positions of the porphyrin skeleton.
