On the double : When a poly(3‐methylthiophene) (PT) film is doped on a bipolar electrode with Bu 4 NPF 6 as supporting electrolyte, the film includes PF 6 − anions with a composition gradient along the potential gradient on the electrode. The use of Et 4 NCl results in partial chlorination of the PT film that reflects the potential gradient of the bipolar electrode (see picture; inset: photograph of the film).
