Fast switching redox processes in aqueous media can be obtained in poly(3,4-ethylenedioxythiophene)/poly(allylamine hydrochloride) (see Figure for chemical structure) multilayer films. Due to the intense near-infrared charge carrier transition of the oxidized form tailing through the visible region, these films provide two color states, which are voltage-controllable.
