The effects of distortion, steric hindrance, distance, and orientation exerted by a variety of porphyrin monomers (strapped and capped) and dimers (singly- and doubly-linked) on the porphyrin redox properties as well as the stability of pos. charged intermediates derived from them were studied. Cyclic voltammograms were obtained in aprotic media for both the 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 was studied in the case of conjugated directly-linked bis(Zn) and bis(Mg) porphyrins.
