After the reaction was completed, stop the reaction with distilled water and extract with ethyl acetate. The organic layer was dried over MgSO4. The solvent was distilled off under reduced pressure and then purified with a silica gel column to obtain compound 3-37 (5.81 g, 48%).

Embodiment 3

[0098] Embodiment three, the preparation of compound 4-37

[0099]

[0100] Add D-3 (5.12g, 16.9mmol), A-1 (9.34, 16.9mmol), tetrakistriphenylphosphine palladium (0.7g, 1.08mmol), potassium carbonate (5.3g, 38.3mmol), toluene 500mL in the reaction vessel , 40mL of ethanol and 40mL of distilled water, stirred at 120°C for 3h. After the reaction was completed, stop the reaction with distilled water and extract with ethyl acetate. The organic layer was dried over MgSO4. The solvent was distilled off under reduced pressure and then purified with a silica gel column to obtain compound 4-37 (5.55 g, 45%).

Abstract

The invention discloses a pyridoindolium compound and an organic light-emitting device thereof. The pyridoindolium compound improves the hole moving degree by adjusting R1 to R2 and Ar1, Ar2 and L groups of an asymmetric pyridoindolium structure. The improvement of group variety can improve the performance of the device. The device manufactured through the novel pyridoindolium compound has the characteristics of high brightness, excellent heat resistance, long service life and high efficiency.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a pyridoindole compound and an organic light-emitting device thereof. Background technique [0002] An organic electroluminescent device (OLED) is a new type of flat display device, generally composed of two opposing electrodes and at least one layer of organic light-emitting compound interposed between the two electrodes. Charges are injected into the organic layer formed between the anode and cathode to form electron and hole pairs, which cause light emission from organic compounds with fluorescent and phosphorescent properties. Organic electroluminescent devices have the characteristics of energy saving, fast response speed, stable color, strong environmental adaptability, no radiation, light weight, and thin thickness. With the rapid development of optoelectronic communication and multimedia fields in recent years, organic optoelectronic materials have...
