Toward a tunable synthetic [FeFe] hydrogenase mimic: single-chain nanoparticles functionalized with a single diiron cluster†
Abstract
We report two novel “clickable” [(μ-S2C2H4NR)Fe2(CO)6] complexes and their incorporation into single-chain nanoparticles. Variations in the characteristic iron–carbonyl stretching bands caused by the polymer scaffolds confirmed changes in the symmetry and electronics of the complexes. This represents the first SCNP-based model of a metalloenzyme bearing a single, bioinspired active site.
