実験手順
5,10-Bis-(2-butyl-octyloxy)-1,6-dithia-dicyclopenta[a,f]naphthalene (1.41 g, 2.3 mmol) was added into a 200 mL flask. The system was vacuumed and backfilled with argon 3 times before 60 mL of anhydrous THF was injected. N-Butyllithium (2.2 mL, 2.5 M in hexane, 5.09 mmol) was added after the mixture was cooled to −78° C. A white precipitate was observed after the mixture was stirred at −78° C. for 30 minutes. Stirring was continued at room temperature for one more hour before the mixture was cooled down to −78° C. again. Trimethyltin chloride (1.20 g, 5.75 mmol) was added in portions and stirring was continued overnight at room temperature. Hexane (100 mL) was added and the organic layer was washed with 150 mL of water. The aqueous layer was extracted with 100 mL of hexane twice. The combined organic layer was dried over anhydrous Na2SO4. Removal of solvent under vacuum yielded a white solid. The colorless crystalline product, 5,10-bis-(2-butyl-octyloxy)-2,7-bis-trimethylstannanyl-1,6-dithia-dicyclopenta[a,f]naphthalene, (1.70 g, ˜79% yield) was obtained after recrystallization from a hexane/iso-propanol mixture. 1H NMR (CDCl3, 500 MHz): δ 7.80 (s, 2H), δ 7.69 (s , 2H), δ 4.25 (d , 4H, J=5.5 Hz), δ 1.99 (m , 2H), δ 1.33 (m , 32H), δ 0.96 (t , 6H, J=7.0 Hz), δ 0.90 (t, 6H, J=7.0 Hz), δ 0.51 (m , 18H).
