Embodiment 1

[0161] Embodiment 1: the synthesis of compound 1

[0162]

[0163] 2.5 g of the above intermediate IM-1 and 0.26 g of NaH were added to 25 ml of dimethylformamide (DMF) and stirred. Among them, 2.83 g of 2-chloro-4,6-diphenylpyrimidine (2-chloro-4,6-diphenylpyrimidine) was dissolved in 30 ml of dimethylformamide, and then slowly added dropwise. After stirring at room temperature, the completion of the reaction was confirmed by thin-layer chromatography, and silica filtration was performed, followed by recrystallization to obtain 2.22 g (yield 49%) of Compound 1.

Embodiment 2

[0165] Embodiment 2: the synthesis of compound 2

[0166]

[0167] Using 4-chloro-2,6-diphenylpyrimidine (4-chloro-2,6-diphenylpyrimidine) instead of 2-chloro-4,6-diphenylpyrimidine, compound 2 was synthesized by the same method as compound 1 .

Embodiment 3

[0169] Embodiment 3: the synthesis of compound 3

[0170]

[0171] Use 2-chloro-4,6-diphenyl-1,3,5-triazine (2-chloro-4,6-diphenyl-1,3,5-triazine) instead of 2-chloro-4,6- Diphenylpyrimidine, compound 3 was synthesized by the same method as compound 1.

Abstract

The present invention relates to a novel compound and, especially, to a novel compound, which has excellent hole and electron transfer characteristics when applied to an organic light emitting element, can attain high triplet state energy and high Tg at the same time, and allows the organic light emitting element to have a low driving voltage, low consumption power, high efficiency, and long lifespan, and to an organic light emitting element comprising the same.

Description

technical field [0001] The present invention relates to a novel compound and an organic light-emitting device comprising the same, in particular to an organic light-emitting device that has excellent hole and electron transfer characteristics, and simultaneously can realize high triplet energy and high Tg, and can have low drive Novel compound with high voltage, low power consumption, high efficiency and long life. Background technique [0002] Recently, organic light-emitting devices capable of self-luminous low-voltage drive are superior in viewing angle and contrast ratio compared with liquid crystal displays (LCDs) which are the mainstream of flat panel display devices, and do not require a backlight. Lightweight and thinner, it is also advantageous in terms of power consumption, and it has a wide range of color reproduction, so it is attracting attention as a next-generation display device. [0003] In organic light-emitting devices, materials used as organic layers ca...
