Embodiment 1
[0065](Compound II-1-4) synthesis
[0066]The synthetic route is as follows:
[0067]
[0068]Synthesis of Compound II-1-4
[0069]1 liters of three flasks, mixing magnetic stirring, nitrogen gas replacement sequentially (0.378 mol) (4- (9H-carbazole-9-yl) phenyl) boric acid 60.27 g (purity 99%, 0.21 mol) And 100 ml of toluene. 0.5 g of PD132 was sequentially added after the nitrogen replacement. After completion, heating heated to 80 ° C. It was initially added to a solution of 44 g of compound P1 (purity 99%, 0.1 mol) and 100 ml of toluene, and the temperature was controlled from 75-90 ° C. Cooling to room temperature, add 100 ml of deionized hydrolysis, stirring for 10 minutes, filtration, and the filter cake was purged with DMF a few times, and 60.36 g of pale yellow solid was filtered, purity 99%, yield 79%.
[0070]Product MS (M / E): 523; Element Analysis (C38Hide21NO2: Theoretical value C: 87.17%, H: 4.04%, N: 2.68%, o: 6.11%; measured value C: 87.16%, H: 4.05%, N: 2.68%, o: 6.11%.
Embodiment 2
[0072](Compound II-1-14) synthesis
[0073]The synthetic route is as follows:
[0074]
[0075]Synthesis of Compound II-1-14
[0076]1 liters of three flasks, mixing magnetic stirring, nitrogen gas replacement sequentially add 40.07 g (0.378 mol), (5-phenyl-5H-benzo [b] carbazole-3-yl) boric acid 70.77 g (purity 99%) , 0.21 mol) and 100 ml of toluene. 0.5 g of PD132 was sequentially added after the nitrogen replacement. After completion, heating heated to 80 ° C. It was initially added to a solution of 44 g of compound P1 (purity 99%, 0.1 mol) and 100 ml of toluene, and the temperature was controlled from 75-90 ° C. Cooling to room temperature, add 100 mL of deionized water hydrolysis, stirring for 10 minutes, filtered, and the filter cake was repeatedly cooked several times, filtered to give 46.41 g of light yellow solid, purity 99%, yield 81%.
[0077]Product MS (M / E): 573; Element Analysis (C42Hide23NO2: Theoretical value C: 87.94%, H: 4.04%, N: 2.44%, o: 5.58%; measured value C: 87.93%, H: 4...
