The development of new electrochromic (EC) materials is important, considering their diverse applications including smart windows, information displays, and functional energy storage devices. EC polymers are one of the main categories of EC chromophores and are widely employed in EC devices (ECDs). In this study, we synthesized a novel EC polymer containing redox-active triphenylamine and viologen and applied it to ECDs. The fabricated ECDs displayed three different colors (magenta, blue, and orange) according to the applied voltage. The fabrication of voltage-tunable multicolor ECDs was also demonstrated using electro-force-assisted dispensing printing.
