Abstract

original image

Electrochromic polymers (ECPs) of tunable green: Two symmetrical donor-acceptor based oligomers were designed, synthesized and chemically polymerized affording solution-processable conjugated polymers of distinct green hues in their neutral state. The polyheterocyclic hybrids exhibited highly transmissive oxidized states, excellent optical contrasts both in the visible and in the near infrared, fast switching times and long-term redox switching stability as expected for practical ECP devices.
