Embodiment 1
[0082] Complex 16 and its preparation
[0083] Synthesis of 2-bromo-9-(2-pyridyl)carbazole:
[0084]
[0085] To a sealed 48 mL tube with a magnetic rotor, 2-bromocarbazole 0001 (3.69 g, 15 mmol), 2-bromopyridine 0002 (1.57 mL, 16.5 mmol), cuprous iodide (0.3 mmL, 0.02 equiv), and 1-Methylimidazole (0.3 mmol, 1.2 equiv), t-BuOLi (18 mmol, 1.2 equiv) and toluene (50 mL), the resulting mixture was bubbled with nitrogen for 10 minutes and then heated to 120° C. and stirred for 8 hours. Cool to room temperature, add water to quench the reaction, extract with ethyl acetate, combine the organic phases, wash with an appropriate amount of saturated aqueous sodium chloride solution and dry over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the obtained crude product was separated and purified by silica gel column chromatography, the eluent was petroleum ether:ethyl acetate=25:1, and a white solid was obtained with a yield of 93%.

Embodiment 2
[0103] Complex 18 and its preparation
[0104] Synthesis of 2-(3-methyl-5-amino-phenol)-9-(2-pyridyl)carbazole 0007:
[0105]
[0106] Add 2-bromo-9-(2-pyridyl)carbazole 0003 (1 equiv), 3-methyl-5-amino-phenol 0006 (1.2 equiv), cuprous iodide (10% ), L-proline (L-Pro, 20%), cesium carbonate (2equiv) and dimethylsulfoxide (0.5M). The resulting mixture was bubbled with nitrogen for 10 minutes and stirred at 120°C for 3 days. After cooling, water and ethyl acetate (EA) were added, and the mixture was filtered. The aqueous phase was extracted with ethyl acetate, and the organic phases were combined, washed with brine, and the organic phase was washed with anhydrous Na 2 SO 4 dry. Using PE:EA=8:1 as eluent, the obtained solution was purified by silica gel chromatography to obtain the target product 0007 (brown viscous liquid, yield 75%).
[0107] Synthesis of 2-bromo-N-isopropyl-aniline 1102:
[0108]
[0109] 15 ml of acetone and 75 ml of acetic acid were added to...
Embodiment 4
[0137] Synthesis of complex 31
[0138] Synthesis of 2-bromo-N-isobutyl-aniline 4102:
[0139]
[0140] 15 ml of acetone and 75 ml of acetic acid were added to a solution of 8 g of o-bromoaniline 1101 in 150 ml of dichloromethane. 6 ml of borane dimethyl sulfide solution was added at 0°C, followed by stirring overnight at room temperature. After the reaction was complete, 25 wt% ammonia solution was added to adjust the pH to 8. After adding 50 ml of water, it was extracted three times with dichloromethane. The organic phase was collected and dried with anhydrous sodium sulfate, and spin-dried to obtain the crude product of compound 4102, which was directly used in the next step (yellow oil, yield 96%).
[0141] Synthesis of phenylenediamine derivative 4103:
[0142]
[0143] Add 2-bromo-N-(isopropyl)-aniline 4102 (1 equiv), 2-(3-amino-phenolyl)-9-(2-pyridyl)carbazole 0005 ( 1.1 equiv), palladium acetate (5%), J-phos (2-(dicyclohexylphosphino)biphenyl, 5%), sodiu...
