Abstract

We demonstrated high catalytic activity (TON = 670, TOF_max = 2.7 s⁻¹) of a water-soluble cobalt phthalocyanine complex (CoPcTS, PcTS = phthalocyaninetetrasulfonate) for visible light-driven photochemical water oxidation and investigated its reaction mechanism by electrochemical and spectroscopic measurements.
