Three primary colors (cyan/magenta/yellow) electrochromic devices based on PEDOT:PSS and ‘electrobase/electroacid’ theory

Abstract

A multicolor electrochromic device (ECD), which can switch among three primary colors of cyan (C), magenta (M) and yellow (Y) has been fabricated successfully. This device contains a working layer using PEDOT:PSS as Cyan-EC material, an ion conductive layer and a counter layer using p-benzoquinone (p-BQ)/4-Hydroxy-TEMPO (4-OH-TEMPO) & phenol red (PR-Y) based on ‘electrobase/electroacid’ theory as Magenta/yellow-EC material. All the materials used are easy to get as they can be obtained from commercial way. It can switch the C/M/Y colors by applying various voltages. Besides, this device has a short response time below 100 ms and an excellent reversibility with no degradation after 2250 cycles. It exhibits great potential in smart displays and interior decorations.
