The best of both worlds: An organic bilayer, composed of a perylene derivative (PV) and a phthalocyanine (H 2 Pc), was found to be a novel example of a photoanode involving a catalytic oxidation in water (see graphic). Based on the action spectrum for photocurrent, it is noted that the widespread visible light absorption (<750 nm) by only the PV can efficiently induce the photoanodic current generation at the interface of H 2 Pc/water coupled with the hole‐conducting character of H 2 Pc.
