Abstract: We investigate here the effect of electronic communication between two Mn(iii) porphyrin π-cation radicals, connected covalently through an ethylene bridge, which exhibit significant electronic communication resulting in strong antiferromagnetic coupling predominantly between two porphyrin radical… read more here.

Control of spin coupling through a redox-active bridge in a dinickel(II) porphyrin dimer: step-wise oxidations enable isolations of a chlorin-porphyrin heterodimer and a dication diradical with a singlet ground state.

Abstract: A dinickel(II)porphyrin dimer has been used here in which the redox-active pyrrole-moiety, similar to the tryptophan residue in diheme enzymes such as MauG and bCcP, has been placed between two Ni(II)porphyrin centers connected via a… read more here.
