Homo Lumo

β-Octasubstituted porphyrins having three different substituents (Ph, Br and NO2) have been synthesized. They exhibited highly red-shifted absorption spectral features with tunable redox properties leading to a very low HOMO–LUMO gap as compared to MTPPs.

Hammett Parameter

A series of 2,3,12,13-tetrabromo-5,10,15,20-tetrakis(4′-substituted phenyl)porphyrins, H2 T(4′-R Ph) PBr4 ( R = OCH3 , t-butyl, H and CO2CH3 ) and their metal ( Co(II) , Cu(II) , and Zn(II) ) complexes were synthesized and their electrochemical redox properties were explored. The plot of E1/2vs. the Hammett parameter (σp) of the substituents (R) follow a fairly linear relationship for the ring centered redox potentials.
