実験手順

7-Bromo-12,12-dimethyl-10-phenyl-10,12-dihydro-indeno[2,1-b]carbazole synthesized in Example 1 (3.0 g), bis(biphenyl-4-yl)-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)phenyl]amine (4.3 g), a toluene/ethanol (4/1, v/v) mixed solvent (50 ml), and a 2M potassium carbonate aqueous solution (10 ml) were added to a nitrogen-substituted reaction vessel and aerated with nitrogen gas for 30 min under ultrasonic irradiation. The mixture was heated after adding tetrakis(triphenylphosphine)palladium (0.4 g), and stirred at 73° C. for 8 hours. After the mixture was cooled to a room temperature, a precipitated crude product was collected by filtration. 1,2-dichlorobenzene (140 ml) was added to the crude product, and the crude product was dissolved while being heated, and after removing insoluble matter by filtration, a filtrate was concentrated under reduced pressure. Purification by recrystallization using 1,2-dichlorobenzene (100 ml) was performed to obtain a white powder of 7-[4-{bis(biphenyl-4-yl)amino}-phenyl]-12,12-dimethyl-10-phenyl-10,12-dihydroindeno[2,1-b]carbazole (3.7 g; yield 71.6%).
