A Red, Green, and Blue (RGB) Polymeric Electrochromic Device (PECD): The Dawning of the PECD Era

摘要

The ability to have three complementary colors, red, green, and blue (RGB) constitutes an important step forward to the use of conducting polymers in polymeric electrochromic devices (PECDs). Although many red and blue colored polymers in their neutral form have been reported, no green colored conducting polymer has been reported to date because of the difficulty to obtain the absorptions required in the visible region to reflect the color green. Herein we report the electrochemical and optical properties of the first electrochemically prepared, neutral, green-colored conjugated polymer. The extreme stability of this polymer after 10000 double potential steps makes it the best, and only, candidate for completing the third leg of color space for polymeric electrochromics.
