Versuchsvorschrift

12,12-dimethyl-10,12-dihydroindeno[2,1-b]carbazole synthesized in Example 1 (35.5 g), 4-bromobiphenyl (35.0 g), sodium bisulfite (6.0 g), a copper powder (2.4 g), 3,5-di(tert-butyl)salicylic acid (9.4 g), potassium carbonate (31.2 g), and dodecylbenzene (52 ml) were added to a nitrogen-substituted reaction vessel, heated, and stirred at 190° C. for 26 hours. After cooled to 120° C., the mixture was stirred after adding toluene (35 ml), and a crude product was collected by filtration. After adding toluene (1.6 L) to the crude product, the crude product was heated and extracted at 110° C. After cooled to a room temperature, the crude product was concentrated under reduced pressure. The product was crystallized with methanol (120 ml) to obtain a white powder of 10-(biphenyl-4-yl)-12,12-dimethyl-10,12-dihydroindeno[2,1-b]carbazole (48.5 g; yield 88.1%).
