Neutral color tuning of polymer electrochromic devices using an organic dye

Author affiliations

Abstract

Herein, we present a facile, one-step method to color tune electrochromic devices (ECDs) that switch between two neutral colors via in situ electrochemical polymerization of electroactive monomers in the presence of a small molecule organic yellow dye using all commercially available materials. These devices exhibited photopic contrasts of ca. 30% without background correction when assembled on flexible PET-ITO substrates. In addition, devices exhibited switching speeds as low as 1 second, color uniformity, and stability. Large defect free ECDs of 100 cm2 were fabricated exceeding the active switch area required for goggles, lenses, and small display applications.
