Abstract

original image

No fade to grey: Electroswitching of emission and coloration was achieved for a combination of a luminescent EuIII complex and an electrochromic molecule of diheptyl viologen (HV2+), 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 HV2+.
