An Intramolecular Cobalt–Peptoid Complex as an Effective Catalyst for Light-Driven Water Oxidation at pH 7

, with a maximal turnover number of about 51 in 45 min. Co-(III) is coordinated and stabilized by terpyridine and bipyridine groups incorporated within the peptoid ligand, which also includes an ethanol group that acts as a proton shuttler and thus facilitates the activity at pH 7.
