Referring to the reaction formula above, 10,11-diphenyl-11H-indeno[1,2-b]quinolin-11-ol (385 mg, 1.00 mmol) and 9-(p-tolyl)-9H-carbazole (291 mg, 1.20 mmol) are placed in a round bottom flask and then dissolved in 5 ml of dichloromethane. Subsequently, 286 of Eaton's reagent is slowly dripped into the flask to promote reaction. After 12 hours of reaction at 100° C., the crude product is extracted with 8 ml of dichloromethane and sodium bicarbonate for three times. Finally, an organic layer of the crude product is dehydrated with magnesium sulfate and concentrated to be sublimated and purified to obtain 521 mg of 10,11-diphenyl-11-(9-(p-tolyl)-9H-carbazol-3-yl)-11H-indeno[1,2-b]quinoline. The percentage yield is 83.4%.
