Abstract
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.

- 39 Synthesis of 5,8-Dibromo-2,3-dihexylquinoxaline (Br2C6Qx)3,6-Dibromo-1,2-diaminobenzene36 (0.30 g, 1.13 mmol) was dissolved in absolute ethanol (60 mL), after which tetradecane-7,8-dione34 (0.28 g, 1.25 mmol) was added. The reaction was then heated at reflux for 3 h under nitrogen. The solvent was then removed via rotary evaporation and the sample purified by silica gel column chromatography with 5:95 (v/v) ethyl acetate/petroleum ether as the eluent. This resulted in the isolation of light-yellow needles in a yield of 80–85%; mp 69.8–70.4 °C. 1H NMR (400 MHz, CDCl3): δ = 7.81 (s, 2 H), 3.07 (t, 3J = 7.6 Hz, 4 H), 1.91 (p, 3J = 7.6 Hz, 4 H), 1.49 (m, 4 H), 137 (m, 8 H), 0.91 (t, 3J = 7.6 Hz, 6 H). 13C NMR (100 MHz): δ = 158.3, 140.2, 132.0, 123.4, 34.8, 31.8, 29.2, 27.8, 22.6, 14.1.

The vial was then placed in a dry box where the cap was removed and 7 mL of anhydrous THF were added. A cap was then crimped onto the vial, and the vial was removed from the glove box where it was then stirred at 100 °C for 48 h. Upon completion, the polymer solution was added to 200 mL of methanol and stirred for 1 h in an ice bath. A dark blue-black precipitate formed and was filtered on a coarse frit multiple times until filtrate appeared yellow/clear. The precipitate was then washed with methanol and hexanes via Soxhlet extraction, after which the chloroform-soluble fraction was isolated to give 105 mg of polymer product.
