Abstract Within this study, we report on the first controlled radical polymerization of styrene- based models of the active site of the [FeFe]-hydrogenase. Three different model complexes based on styrene were prepared including propanedithiolato-bridged, 2- azapropanedithiolato-bridged, and bifunctional styrene iron complex. These model complexes were copolymerized with styrene using free radical and the reversible addition ...
