Abstract

Facile protonation of α-octabutoxyphthalocyaninato zinc(II) (Zn(OBu)8Pc) occurs to afford up to tetra-protonated species stabilized by intramolecular hydrogen bonding, resulting in positive shifts of the reduction potentials of Zn(OBu)8PcHnn+ (n = 1–4) with increasing the number of protons attached to facilitate electron-transfer reduction.
