[0049] Their preparation method can specifically be as follows:
[0050] Add 1,5-azacarbazole (2.0g, 11.8mmol), p-bromoiodobenzene (3.33g, 11.8mmol), cuprous iodide (0.05g, 0.25mmol), K 2 CO 3 (3.45g, 25mmol) and 18-crown-6 (6.6mg, 0.25mmol) were dissolved in 5ml DMPU solution. in N 2 Under the condition of protection, the temperature was raised to 180°C, and the reaction was carried out for 48h. After the reaction was terminated, it was cooled to room temperature, extracted, spin-dried, and dichloromethane: methanol 15:1 was passed through the column to obtain 2.5 g of product (1), yield: 66%.
[0051] Compound (1) (1.5g, 4.6mmol), 9-anthraceneboronic acid (1.1g, 5.1mmol), 25ml of 2M potassium carbonate aqueous solution was dissolved in 25ml of ethanol, 50ml of toluene solvent in a 250ml one-necked flask. in N 2 Under protected conditions, Pd(PPh3)4 (0.1 g, 0.1 mmol) was added. The temperature was slowly raised to 110°C, and the mixture was reacted under reflux for 24h....

[0062] 150nm ITO (Indium Tin Oxide) glass was ultrasonically cleaned in detergent and deionized water for 30 minutes sequentially. Then vacuum dry for 2 hours (105°C), then put the ITO (indium tin oxide) glass into the plasma reactor for 5 minutes of oxygen plasma treatment, then use the spin coating process to prepare the organic layer in turn, and finally transfer it to the vacuum chamber to prepare the electron injection layer and cathode. Firstly, 30nm PEDOT:PSS was prepared by spin-coating on ITO glass, and annealed at 120°C for 10 minutes. The exciton blocking layer was prepared by spin-coating PVK chlorobenzene solution with a thickness of 20 nm, and annealed at 170° C. for 30 minutes. m-PO15NCzDPA methanol solution spin coating method to prepare the light-emitting layer and electron transport layer 60nm, 100 ℃ annealed for 10 minutes. Wherein, the light-emitting layer is 30nm, doped with yellow light dye 0.05wt% TBRb, and green light dye 15wt% C545T. A 1.5nm LiQ ele...
