Metallophthalocyanine-based redox active metal–organic conjugated microporous polymers for OER catalysis

We report the design and synthesis of two Co2+ and Zn2+ phthalocyanine (PC)-based redox active metal–organic conjugated microporous polymers (MO-CMP), CoCMP and ZnCMP, respectively, obtained by a Schiff base condensation reaction. CoCMP, where Co2+ is stabilized by N4-coordination of PC, has shown stable and efficient electrocatalytic activity towards the OER with a low overpotential of 340 mV.
