title: Color tuning of black for electrochromic polymers using precursor blends.
abstract: We demonstrate a facile controlling of the optical and colorimetric properties of a donor-acceptor conjugated polymer simply by varying the mix ratio of two precursors in a precursor blend. The conversion of a precursor blend results in an entirely new donor-acceptor polymer, distinct from the conjugated polymer of each precursor. Careful optimization of the mix ratio of two precursors results in a black electrochromic polymer.
