Abstract Integrating molecular catalysts into designed frameworks often enables improved catalysis. Compared with porphyrin‐based frameworks, metal‐corrole‐based frameworks have been rarely developed, although monomeric metal corroles are usually more efficient than porphyrin counterparts for the electrocatalytic oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). We herein report on metal‐corrole‐based porous organic polymers (POPs) as ORR and OER electrocatalysts. M‐POPs (M=Mn, Fe, Co, Cu) were synthesized by coupling metal 10‐phenyl‐5,15‐(4‐iodophenyl)corrole with tetrakis(4‐ethynylphenyl)methane. Compared with metal corrole monomers, M‐POPs displayed significantly enhanced catalytic activity and stability. Co‐POP outperformed other M‐POPs by achieving four‐electron ORR with a half‐wave potential of 0.87 V vs. RHE and reaching 10 mA cm −2 OER current density at 340 mV overpotential. This work is unparalleled to develop and explore metal‐corrole‐based POPs as electrocatalysts.
