Abstract: Abstract We report donor-acceptor copolymers incorporating electron-donating dimethylsilole and electron-withdrawing diketopyrrolopyrrole (DPP) units. To investigate effects of alkyl chain attached to the DPP unit, 2-decyltetradecyl (24-alkyl) group and 7-decylnonadecyl (29-alkyl) with linear space group were… read more here.
