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.

Abstract: Carboxylated GAP copolymers (polyGA-carboxylate) compounds (1–7), were synthesized by the simultaneous substitution reaction with PECH, sodium azide, and sodium carboxylate in DMSO. The synthesized compounds (1–7) were characterized by various analysis tools, such as Fourier… read more here.
