Description: The synthesis of a new dialkyl-functionalized quinoxaline acceptor, 5,8-dibromo-2,3-dihexylquinoxaline, is reported, along with its cross-coupling with 2,3-dihexylthieno[3,4-b]pyrazine via direct arylation polymerization. The resulting ambipolar-acceptor polymer poly(2,3-dihexylthieno[3,4-b]pyrazine-alt-2,3-dihexylquinoxaline) exhibits a low bandgap of 1.07 eV and high solubility. The results of initial organic photovoltaic devices are also reported.
