Embodiment 1

[0096] Example 1: Synthesis of Compound 1

[0097]

[0098] 2.0 g of the above Intermediate 01, 4.6 g of 9-(3'-bromo-[1,1'-biphenyl]-3-yl)-9H-carbazole, 1.4 g of t-BuONa, 0.35 g of Pd 2 (dba) 3 , 0.5ml (t-Bu) 3 P was dissolved in 30 ml of toluene, followed by reflux stirring. After confirming the termination of the reaction by TLC, the organic layer was extracted with MC, filtered under reduced pressure, and purified by column purification to obtain 1.77 g of compound 1 (yield: 35%).

[0099] m / z: 525.18 (100.0%), 526.19 (40.3%), 527.19 (8.1%), 528.19 (1.2%), 526.18 (1.1%)

Embodiment 2

[0100] Example 2: Synthesis of Compound 2

[0101]

[0102] Compound 2 was synthesized by the same method as Compound 1 except that the above-mentioned Intermediate 05 was used.

[0103] m / z: 526.18 (100.0%), 527.18 (40.5%), 528.19 (7.5%), 529.19 (1.0%)

Embodiment 3

[0104] Example 3: Synthesis of Compound 3

[0105]

[0106] Compound 3 was synthesized by the same method as Compound 1 except that the above-mentioned Intermediate 33 was used.

[0107] m / z: 542.16 (100.0%), 543.16 (40.0%), 544.16 (8.3%), 544.15 (4.5%), 545.16 (1.9%), 543.15 (1.5%)

Abstract

An organic light emission compound of the present invention has excellent charge transport characteristics while having high triplet energy and Tg, thereby allowing an organic light emitting device to have a low driving voltage, high efficiency, low-consumption power, and a long lifespan when the organic light emission compound is applied to the organic light emitting device.

Description

technical field [0001] The present invention relates to a novel light-emitting compound and an organic light-emitting element including the same. Background technique [0002] Recently, organic light-emitting elements of self-luminous type that can be driven at low voltages are superior in viewing angle, contrast, etc., compared to liquid crystal displays (LCDs), which are the mainstream of flat panel display elements. , it is also advantageous in terms of power consumption and has a wide color reproduction range, so it has attracted attention as a next-generation display element. [0003] Materials used as an organic layer in an organic light-emitting element can be roughly classified into light-emitting materials, hole-injection materials, hole-transport materials, electron-transport materials, electron-injection materials, and the like according to their functions. The above-mentioned light-emitting materials can be divided into macromolecules and low-molecules according...
