Catechol oxidation by three CuII complexes of 1,4,7,10-tetraaza-cyclododecane (cyclen) attached to a cyclotriphosphazene core follows enzyme-like saturation kinetics and an intramolecular dinuclear pathway with significant cooperativity (θ ≈ 1.5 with a maximum of 2 for two binding sites), but not so for the untethered CuII–cyclen with a lower kcat/Km.
