Control of electron-transfer reduction by protonation of zinc octabutoxyphthalocyanine assisted by intramolecular hydrogen bonding

摘要

Facile protonation of a-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)_8PcH_n~(n+) (n =1-4) with increasing the number of protons attached to facilitate electron-transfer reduction.
