Reaction Steps

50% aqueous NaOH solution (4 mL) was added to a well-stirred mixture of 2,8-dichloroindolo[3,2-b]carbazole (0.65 g, 2 mmol) as prepared above, benzyltriethylammonium chloride (90 mg, 0.4 mmol), and 1-bromododecane (1.99 g, 8 mmol) in DMSO (20 mL) in a 100-mL flask, and the resultant mixture was stirred at room temperature for 1 h and then at 50° C. for 4 h. Subsequently, the mixture was poured into MeOH (200 mL), and the precipitated yellow solid was filtered and washed 3 times each with water, N,N-dimethylformamide, methanol, and acetone, yielding 1.16 g (88.0%) of 2,8-dichloro-5,11-didodecylindolo[3,2-b]carbazole, compound (3), after drying in vacuo. It was then subject to train sublimation to obtain electrically pure samples for OTFT fabrication.
