Problems solved by technology

In the existing organic electroluminescent devices, the most important problem is life and efficiency. With the large area of ​​the display, the driving voltage is also increased, and the luminous efficiency and power efficiency also need to be improved, and a certain service life must be guaranteed. Therefore, organic materials must solve these efficiency or lifetime problems, and it is necessary to continuously develop new materials for organic light-emitting devices with high efficiency, long life, and suitable for mass production.

[0147]

[0148] (1) Sub 1-I-A1 Synthesis

[0149] Tetrabromo-p-benzoquinone (43.0 g, 74.7 mmol) was dissolved in ethyl 2-methoxyacetate (400 mL, 2-methoxyethyl acetate) and stirred at 60°C. After cooling to room temperature, 27% ammonium hydroxide solution (43 mL) was added dropwise, stirred at 80° C. for 3 hours, and stirred at room temperature overnight. The precipitate obtained by filtration was washed several times with distilled water, washed with acetone and dried to obtain compound sub 1-I-A1 (25.1 g, yield: 90%).

[0150] (2) Sub 1-II-A1 synthesis

[0151] First weighed sub 1-I-A1 (25g, 84.5mmol) and reducing agent Na 2 S 2 o 4 (44.1g, 253.4mmol) was added into a 1000mL two-necked bottle, and then the air in the two-necked bottle was completely replaced with Ar. Add 500 mL of double-distilled water into the two-necked bottle with a syringe, stir the reaction at 40°C for 1 hour to stop the reaction, wait until the light yellow solid is completely precipitated, f...

preparation example 2-11

[0163] The compounds in Table 2 were synthesized in a similar manner to Compound Preparation Example 1, except that raw material 3 in Table 2 was used instead of phenylboronic acid, and raw material 2 was used instead of 4-biphenylboronic acid.
