Iron Phthalocyanine-Knitted Polymers as Electrocatalysts for the Oxygen Reduction Reaction

[EN] Knitted iron phthalocyanine-based porous polymer networks (K-FePcs) were prepared in a single step using solvent-knitting strategies with commercial iron phthalocyanine as a building monomer. The incorporation of different aryl comonomers (biphenyl and 1,2,4,5-tetraphenylbenzene) to FePc allowe...
