Abstract
An electrochromic polymer includes a formula of MCL represents a meta-conjugated linker, and Ac represents an aromatic moiety. The disclosed electrochromic polymer has an absorption onset equal to or smaller than 420 nm in a neutral state and has absorption in visible and/or near-infrared wavelengths in an oxidized state, thus the disclosed electrochromic polymer shows a high transparency and a high optical contrast when used in electrochromic devices.
