A mixture of 10.9 g (35.1 mmol) 4-iododibenzo[b,d]thiophene, 8.6 g (35.1 mmol) of 3-bromo-9H-carbazole, 4.46 g (70.2 mmol) of Cu, 14.55 g (100.1 mmole) of K2CO3 was stirred in 100 ml dimethylformamide, the reaction mixture was then heat to 160° C. for about overnight under nitrogen. Then cooled to 100° C., the solution was filtered. To receive the filtrate, and most of the dimethylformamide was removed under reduced pressure from the filtrate. The distillation was extracted with ethyl acetate and water, dried with anhydrous magnesium sulfate, the solvent was removed and the residue was purified by column chromatography on silica(hexane-dichloromethane) to give product 8.7 g (58%).
