Abstract

A series of mono ferrocene Schiff-base porphyrins in which the ferrocene unit is disposed in different orientations to the porphyrin core have been synthesized from meso-5(o- or p)aminophenyl-10,15,20-triphenyl-21,23-H-porphyrin and ferrocenecarboxaldehyde. The optical and magnetic resonance spectral features of these derivs. reveal weak interactions between ferrocene and porphyrin units. The kinetics of metal incorporation into the free-base ferrocenyl porphyrins indicate the steric features induced by the ferrocene unit. Electrochem. redox behavior of the compds. shows that the ferrocene and porphyrin entities behave as independent units. Steady-state photolysis expts. reveal no internal electron-transfer, although the energies of the CT state of porphyrin-ferricenium ion indicate the feasibility of electron transfer in these systems.
