Embodiment 1

[0100] The synthetic route of compound CP001:

[0101]

[0102] In a 250 mL round bottom flask, 2-bromo-4,6-diiodo-pyrimidine (10 mmol), 6-boronic acid-isoquinoline (12 mmol) and Pd(PPh 3 ) 4 (0.3mmol) was added to a mixture of toluene (30mL) / ethanol (20mL) and potassium carbonate (12mmol) aqueous solution (10mL), and the reaction was refluxed under nitrogen atmosphere for 12h. The resulting mixture was cooled to room temperature, added to water, and filtered through a pad of celite. The filtrate was extracted with dichloromethane, washed with water, and dried over anhydrous magnesium sulfate. After filtration and evaporation, the crude product was purified by silica gel column chromatography The intermediate product CP001-1 was obtained.

[0103] In a 250 mL round bottom flask, the intermediate product CP001-1 (10 mmol), 2-boronic acid-anthracene (22 mmol) and Pd(PPh 3 ) 4 (0.3mmol) was added to a mixture of toluene (30mL) / ethanol (20mL) and potassium carbonate (12mmol...

Description

technical field [0001] The present application relates to the technical field of organic electroluminescence materials, in particular to an organic compound, a display panel and a display device. Background technique [0002] After decades of development, OLED has come a long way. Although its internal quantum efficiency is close to 100%, its external quantum efficiency is only about 20%. Most of the light is confined inside the light-emitting device due to factors such as substrate mode loss, surface plasmon loss, and waveguide effect, resulting in a large amount of energy loss. [0003] In the top-emitting device, an organic capping layer (CappingLayer, CPL) is deposited on the translucent metal electrode Al to adjust the optical interference distance, suppress the reflection of external light, and suppress the extinction caused by the movement of surface plasmons, thereby improving the extraction of light. Efficiency, improve luminous efficiency. [0004] OLED has high...
