Abstract: Metallopolymers composed of polymers and catalytically active diiron-disulfide ([2Fe-2S]) complexes. [FeFe]-hydrogenase mimics have been synthesized and used to initiate polymerization of various monomers to generate metallopolymers containing active [2Fe-2S] sites which serve as catalysts for a hydrogen evolution reaction (HER). Vinylic monomers with polar groups provided water solubility relevant for large scale hydrogen production, leveraging the supramolecular architecture to improve catalysis. Metallopolymeric electrocatalysts displayed high turnover frequency and low overpotential in aqueous media as well as aerobic stability. Metallopolymeric photocatalysts incorporated P3HT ligands to serve as a photosensitizer to promote photoinduced electron transfer to the active complex.
