Title: Immobilization of an Amphiphilic Molecular Cobalt Catalyst on Carbon Black for Ligand-Assisted Water Oxidation

We have prepared the amphiphilic molecular catalyst [Co III(L OC18)(pyrr) 2]ClO 4, where L OC18 is the deprotonated form of N,N'-[4,5-bis(octadecyloxy)-1,2- phenylene]dipicolinamide. Species can be anchored onto a carbon black support to yield the assembly 1@CB, which can catalyze water oxidation at an affordable onset overpotential of 0.32 V, with a current density of 10 mA/cm 2 at 0.37 V. Furthermore, 1@CB displays TOF = 3850 h –1. A mechanism is proposed based on the experimental and density-functionaltheory- calculated data.
