No fade to grey : Electroswitching of emission and coloration was achieved for a combination of a luminescent Eu III complex and an electrochromic molecule of diheptyl viologen (HV 2+ ), indicating that such a combination could be used as a display material with dual emissive and reflective modes. The Prussian blue (PB)‐modified electrode improved the response time and reversibility for the switching of emission and coloration, by acting as a counter electrode for the electrochromism of HV 2+ .
