their Zn(II) derivatives the reverse order is observed for the bromoderivatives. The ability of the Zn2+ ion to make the bromoporphyrins resistant to distortion by bridging the central cavity can be attributed as the cause for this interesting observation. Cyclic voltammetric studies exhibit characteristic quasi-reversible/irreversible oxidation–reduction features for all the free-bases and Zn(II) derivatives
