Abstract

The interaction between two "spatially close" porphyrins plays important roles in biochemical functions. The present study focuses on the effects of distortion, steric hindrance, distance and orientation exerted by a variety of porphyrin monomers (strapped and capped) and dimers (mono- and doubly-linked) on their redox properties as well as the stability of positively charged intermediates derived from them. Cyclic voltammograms have been conducted in aprotic media on both free bases and their metal complexes (Zn and Mg). The effect of the nature of supporting electrolyte on the anodic peak potentials and wave separation has been studied in the case of conjugated directly-linked bis-zinc and bis-magnesium porphyrins.
