The remarkable stability of the electrochromic title compound in aqueous base (KOH) has been demonstrated over 2 · 10 4 charge/dischage cycles. Conducting polymer films containing inorganic anions usually show high sensitivity to water, losing activity rapidly, but the dodecylsulfate surfactant anion improves the stability to the extent that efficient cycling is possible even in basis media.
