10.0 g (20.28 mmol) of 10-ethyl-10H-phenanthro[9,10-b]carbazol-3-yl trifluoromethanesulfonate synthesized in Synthetic Example 9, 3.71 g (30.42 mmol) of phenylboronic acid, and 0.23 g (0.20 mmol) of Pd(PPh3)4 were dissolved in 150 ml of toluene, and 4.30 g (40.56 mmol) of Na2CO3 was put into 50 ml of distilled water, and then refluxed and agitated for 5 hours. After the reaction was finished, extraction was performed by dichloromethane, filtering was performed by silica gel, and the column was used at a ratio of Hexane:MC=7:3 (v/v) to obtain 5.81 g of 10-ethyl-3-phenyl-10H-phenanthro[9,10-b]carbazole (yield 68%).
