Embodiment 1
[0084] This material example provides a luminescent material based on fluorene aromatic amine compounds, and its synthesis route is as follows:
[0085]
[0086] Its preparation method is as follows:
[0087] (1) Add reactant B-4 (110mmol) into a three-necked flask, add 500mL of anhydrous tetrahydrofuran, replace with nitrogen three times, then cool the reaction system to -78°C, and add (2.5M) n-BuLi (110mmoL) dropwise , stirred at -78°C for 2h. Reactant A-4 (100mol) was dissolved in tetrahydrofuran and added dropwise to the reaction system. After the dropwise addition was completed, the temperature was raised to room temperature and stirred for 10 h. Distilled water was added to terminate the reaction, the organic phase was collected by liquid separation, and dried by adding anhydrous magnesium sulfate. The remaining water was removed, anhydrous magnesium sulfate was removed by filtration, and the organic phase was removed by a rotary evaporator to obtain a solid organic...
