| Popis: | The electrosynthesis of a low band-gap and neutral-state green linear polymer incorporating a BODIPY core as the acceptor and bis(3,4-ethylenedioxythiophene) (bis-EDOT) as the donor has been described. Resulted polymer exhibited two well-defined absorption bands at 430 and 690 nm allowing it to absorb light in the whole visible spectrum. The resulting highly conjugated polymer showed electrochromic behavior and the color changes from neutral-state green to oxidized-state dark blue. The electrogenerated thin film of the polymer displayed good hole mobility in solid state and registered a photo-electrochemical response when light was applied. |
