[0127] 1. Synthesis of compounds

[0128] Synthetic Example 1: Synthetic Organic Compound (1)

[0129]

[0130] Synthetic intermediate (1-a):

[0131] Put o-bromofluorobenzene (1.5eq), 1-fluorocarbazole (1eq), and potassium tert-butoxide (5eq) into a single-necked bottle, add 250mL of DMF, and react at 120°C for 8 hours. After the reaction solution was evaporated to dryness in vacuo, it was washed with dichloromethane, and the incompletely dissolved solid was filtered off. The filtrate was spin-dried and separated and purified by silica gel chromatography to obtain white solid intermediate (1-a) with a yield of 89%.

[0132] Synthetic intermediate (1-b):

[0133] Place diboronic acid pinacol ester (1.5eq), intermediate (1-a) (1eq), Pd(dppf) in a dry two-necked flask 2 Cl 2 (0.05eq), potassium acetate (4eq), and then add 250mL of a mixed solution of dioxane and water at a ratio of 3:1, stir and react at 90°C for 12 hours, cool to room temperature, ...

Abstract

The invention discloses a nitrogen-containing heterocyclic ring compound and application thereof. The nitrogen-containing heterocyclic ring compound has a structure as shown in a general formula (1). When the material is used in an OLED, especially as a main body material of a light-emitting layer, the external quantum efficiency of a device can be improved, and the service life of the device can be prolonged. Meanwhile, the compound disclosed by the invention not only has a relatively stable eight-membered ring-containing structure, but also has a relatively large ring-shaped structure, so that a conjugated system can be increased, the structure is more stable, the stability of a device can be improved, and meanwhile, the starting voltage is reduced, so that the service life of the device is prolonged.
