Abstract
Electrochromic polymers that include a plurality of π-conjugated chromophores in spaced relation with one another, and a plurality of conjugation-break spacers (CBSs), where at least one CBS separates adjacent chromophores, are provided. The chromophores may be colored in the neutral state, and multicolored to transmissive in different oxidation states.
