The diverse functionalization of the polymeric support phase diiron disulfide [2Fe-2S] metallopolymer electrocatalysts offers a route to enhanced generation molecular hydrogen via water-splitting. Click chemistry has been shown be useful tool in post-polymerization for wide range materials under mild conditions, which is requirement metallopolymers due presence iron carbonyl (Fe-CO) bonds active site. In this study, we developed new synthetic methodology functionalize using atom transfer radical polymerization (ATRP) and azide-alkyne "click" cycloaddition. Azide functional were prepared by ATRP 3-azidopropyl methacrylate (AzPMA) with either methyl (MMA) or 2-(dimethylamino)ethyl (DMAEMA), followed copper-catalyzed cycloaddition terminal alkynes. Both families PMMA PDMAEMA metallo-copolymers found retain Fe-CO from catalyst site after click reactions and, more importantly, exhibited high electrocatalytic activity electrochemical water-splitting pH-neutral aqueous conditions.
