Embodiment 1
[0048] Compound 3 provided by the present invention can be synthesized by the following method.
[0049]
[0050] (1) In a 500ml three-necked flask, add 4,6-dichloro-1,3,5-triazin-2-amine (16.50g, 100mmol), 4-tert-butylphenylboronic acid (35.60g, 200mmol), Potassium carbonate (27.64g, 200mmol), toluene 150mL, ethanol 75mL, water 75mL, in N 2 Tetrakis(triphenylphosphine)palladium (0.35 g, 3 mmol) was added under protection, the reaction was controlled at 85° C., and the reaction was carried out for 12 h, and the reaction was completed by liquid phase monitoring. Cool to room temperature, wash twice with water, add activated carbon for decolorization, filter, concentrate to obtain a light yellow solid, recrystallize twice from ethanol, and dry under vacuum to obtain 4,6-bis(4-tert-butylphenyl)-1,3, 32.44 g of 5-triazin-2-amine, yield 90%.
[0051] (2) In a 500ml three-necked flask, add phenanthrenequinone (10.41g, 50mmol), 4,6-di(4-tert-butylphenyl)-1,3,5-triazin-2-amine (2...
Embodiment 2
[0053] Compound 12 provided by the present invention can be synthesized by the following method.
[0054]
[0055] (1) In a 500ml three-necked flask, add 4,6-dichloro-1,3,5-triazin-2-amine (16.50g, 100mmol), (9,9-dimethyl-9H-fluorene-2 -base) boric acid (47.62g, 200mmol), potassium carbonate (27.64g, 200mmol), toluene 150mL, ethanol 75mL, water 75mL, in N 2 Tetrakis(triphenylphosphine)palladium (0.35 g, 3 mmol) was added under protection, the reaction was controlled at 85° C., and the reaction was carried out for 12 h, and the reaction was completed by liquid phase monitoring. Cool to room temperature, wash twice with water, add activated carbon for decolorization, filter, concentrate to obtain a light yellow solid, recrystallize twice from ethanol, and dry under vacuum to obtain 4,6-bis(9,9-methyl-9H-fluorene-2- base)-1,3,5-triazin-2-amine 42.29g, yield 88%.
[0056] (2) In a 500ml three-necked flask, add phenanthrenequinone (10.41g, 50mmol), 4,6-di(9,9-methyl-9H-fluoren...
Embodiment 3
