[0047] Example 1:
[0048] (R)-2-(9H-carbazol-9-yl)-3-(9,9-dimethylacridine-10(9H)-yl)benzo(b)dinaphtho[2,1- e: Synthesis of 1',2'-g][1,4]dioxatriene-1,4-dicarbonitrile, the synthetic route is as follows:
[0049]
[0050] Under the protection of argon, add tetrafluoroterephthalonitrile (0.20g, 1.00mmol) and (R)-1,1'-bi-2-naphthol (0.286g, 1.00mmol) into a three-necked flask, use 10mL DMF is dissolved and K is added 2 CO 3 (0.28g, 2.00mmol), the reaction was stirred at room temperature for 12 hours; then 9,10-dihydro-9,9-dimethylacridine (0.21g, 1.00mmol) and potassium carbonate (0.14g, 1.00 mmol), the reaction was stirred at 80°C for 12 hours; after the reaction solution was cooled to room temperature, 9H-carbazole (0.21g, 1.25mmol) and potassium carbonate (0.17g, 1.25mmol) were added, and the reaction was stirred at room temperature for 8 hours . After the reaction, the reaction solution was poured into 150 mL of saturated brine to precipitate solids, and filtered with suction...
