A flexible polymer for selective seawater splitting : Incorporation of a monomeric Mn‐porphyrin that is normally catalytically inactive, into a flexible poly(terthiophene) film yields a remarkable light‐assisted water oxidation catalyst with an apparent overpotential for water oxidation of a mere 0.09 V. The catalyst generates exclusively O 2 and no Cl 2 in seawater at 0.9 V versus Ag/AgCl.
