preparation example Construction

[0063] The preparation method of the compound of the embodiment of the present invention is described in detail below:

[0064] Synthesis of compound 1

[0065]

[0066] Magnesium strips (15.44g, 643.5mmol) and diethyl ether (100mL) were placed in a dry round bottom flask under nitrogen, and iodine (119mg) was added. Then a solution of ether (200mL) dissolved with 2-bromobiphenyl 2-bromotoluene (50.00g, 214.49mmol) was slowly dropped into the flask, and after the addition was completed, the temperature was raised to 35°C and stirred for 3 hours; the reaction solution was lowered to 0°C, a solution of ether (200mL) dissolved with adamantanone (48.33g, 321.7mmol) was slowly dropped into it, and after the addition was completed, the temperature was raised to 35°C and stirred for 6 hours; the reaction solution was cooled to room temperature, and added 5% hydrochloric acid to pH<7, stirred for 1 hour, added diethyl ether (200mL) for extraction, combined the organic phases, drie...

Embodiment 1

[0183] The anode 10 is prepared by the following process: the thickness is The ITO substrate was cut into a size of 40mm × 40mm × 0.7mm, and it was prepared into a top emission experimental substrate with a cathode overlapping area, an anode and an insulating layer pattern by using a photolithography process, using ultraviolet ozone and O 2 :N 2 Plasma is used for surface treatment to increase the work function of the anode (experimental substrate) and to clean the experimental substrate.

[0184] On the experimental substrate (anode 10) vacuum evaporation HAT-CN to form a thickness of The hole injection layer (HIL) 201.

[0185] NPB is vacuum evaporated on the hole injection layer 201 to form a thickness of The hole transport layer (HTL) 202.

[0186] Evaporate TCTA on the hole transport layer 202 to form a thickness of Electron blocking layer (EBL) 203 .

[0187] α, β-ADN is used as the main body, and BD-1 is doped at a doping ratio of 3%, and evaporated on the ele...

Embodiment 2-19

[0197] The organic electroluminescence device was fabricated by the same method as in Example 1, except that, when forming the electron transport layer (ETL) 206, the compounds shown in Table 1 were used instead of Compound 1.

Description

technical field [0001] The present invention relates to the technical field of organic materials, in particular, to an organic compound and an electronic device containing the organic compound. Background technique [0002] In recent years, organic electroluminescent device (OLED: Organic electroluminescent device), as a new generation of display technology, has gradually entered people's field of vision. A common organic electroluminescent device is composed of an anode, a cathode, and more than one organic layer arranged between the cathode and the anode. When a voltage is applied to the cathode and anode, the two electrodes generate an electric field. Under the action of the electric field, the electrons on the cathode side move to the light-emitting layer in the organic layer, and the electrons on the anode side also move to the light-emitting layer. The two combine to form excitons in the light-emitting layer. The exciton releases energy in the excited state, and emits...
