[0107] Synthesis of Compound H002

[0108]

[0109] In a 250ml round bottom flask, add aphenoxanthene borate (10mmol), 2-bromo-4,6-diphenylpyridine (12mmol), and tetrakis(triphenylphosphine)palladium (0.6mmol) into 15ml In tetrahydrofuran THF, add 10ml of 2M K 2 CO 3 solution, stirred at a certain speed, and the resulting mixed solution reactant was heated to reflux at a reaction temperature of 80°C for 18 hours; after the reaction was completed, it was cooled to room temperature and 100ml of water was added, and the resulting mixture was filtered and washed three times in 25ml of dichloroethane , and finally dried over anhydrous magnesium sulfate. The resulting residue was further separated and purified through a silica gel column to obtain the product H002.

The compound according to the present invention has a structure shown in formula (I): wherein, A is a nitrogen-containing heteroaromatic ring substituent; L is selected from single bonds, substituted or unsubstituted C1-C12 alkyls, substituted or unsubstituted C3-C8 cycloalkyl, substituted or unsubstituted C1-C8 alkoxy, substituted or unsubstituted C3-C8 heterocyclyl, substituted or unsubstituted C6-C40 aryl, substituted or unsubstituted C4-C40 Any one or more than one of the heteroaryl groups.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence materials, in particular to a compound, a display panel and a display device. Background technique [0002] As a new generation of display technology, organic electroluminescent materials (OLED) have the advantages of ultra-thin, self-luminous, wide viewing angle, fast response, high luminous efficiency, good temperature adaptability, simple production process, low driving voltage, and low energy consumption. It has been widely used in industries such as flat panel display, flexible display, solid state lighting and vehicle display. [0003] According to the light-emitting mechanism, the light emitted by OLED can be divided into two types: electroluminescence and electrophosphorescence. Fluorescence is the light emitted by the radiative decay transition of singlet excitons, and phosphorescence is the light emitted by the radiative decay of triplet excitons to the ground state....
