The improvement of molecular ordering in conducting polymers from disordered aqueous solution state to highly ordered solid state is investigated by K. Lee and co‐workers on page 8625. A well‐ordered structure, like a wall, can be formed by painting a mixture solution of PEDOT:PSS with an ionic liquid and then evaporating the water solvent. The different colors in the wall represent units of conducting PEDOT (positively doped) (blue), anionic PSS (orange), the cation of the ionic liquid (yellow), and its counter anion (red). The lighting by the lamp indicates the highly conducting state of PEDOT:PSS, which results from its crystalline formation.
