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.

Polymerization Conditions

Polymerization conditions for direct arylation polymerization (DArP) now allow for the preparation of conjugated polymers, such as donor–acceptor copolymers, where undesired couplings (donor–donor, acceptor–acceptor, or branching defects) are undetectable.
