Embodiment 1

[0140] Embodiment 1: the synthesis of compound 1

[0141]

[0142] In a round bottom flask, dissolve 3.0 g of intermediate A and 3.4 g of (10-phenylanthracene-9-yl) boric acid in 100 ml of toluene, and add 15 ml of K 2 CO 3 (2M) and 0.33g of Pd(PPh 3 ) 4 , and then reflux stirring. The reaction was confirmed by TLC, and if the reaction was complete, water was added, and the organic layer was extracted with MC. After filtration under reduced pressure, it was purified on a column to obtain 2.0 g of compound 1 (yield 43%).

Embodiment 2

[0143] Embodiment 2: the synthesis of compound 2

[0144]

[0145] In a round bottom flask, dissolve 3.0 g of Intermediate A and 4.0 g of (10-(naphthalene-2-yl)anthracen-9-yl)boronic acid in 105 ml of toluene, and add 15 ml of K 2 CO 3 (2M) and 0.33g of Pd(PPh 3 ) 4 , and then reflux stirring. The reaction was confirmed by TLC, and if the reaction was complete, water was added, and the organic layer was extracted with MC. After filtration under reduced pressure, it was purified on a column to obtain 2.1 g of compound 2 (yield 40%).

Embodiment 3

[0146] Embodiment 3: the synthesis of compound 3

[0147]

[0148] In a round bottom flask, dissolve 3.0 g of Intermediate A and 4.0 g of (10-(naphthalene-1-yl)anthracen-9-yl)boronic acid in 105 ml of toluene, and add 15 ml of K 2 CO 3(2M) and 0.33g of Pd(PPh 3 ) 4 , and then reflux stirring. The reaction was confirmed by TLC, and if the reaction was complete, water was added, and the organic layer was extracted with MC. After filtration under reduced pressure, it was purified on a column to obtain 2.3 g of compound 3 (yield 44%).

Abstract

An organic light-emitting compound according to the present invention has superb hole and electron transport characteristics, excellent ability to maintain blue light emission, superb light-emitting efficiency, high color purity and efficiency and long lifespan characteristics, and thus can impart superb characteristics to an element when used in an organic light-emitting element.

Description

technical field [0001] The present invention relates to novel light-emitting compounds and organic light-emitting elements comprising them. Background technique [0002] Recently, self-illuminating organic light-emitting elements that can be driven at low voltages have superior viewing angles and contrast ratios compared to liquid crystal displays (LCDs) that are the mainstream of flat panel display elements. Lightweight and thin, it is also advantageous in terms of power consumption, and the color reproduction range is wide, so it is attracting attention as a next-generation display element. [0003] Materials used as organic layers in organic light-emitting devices can be roughly classified into light-emitting materials, hole-injecting materials, hole-transporting materials, electron-transporting materials, and electron-injecting materials according to their functions. The above-mentioned luminescent materials can be divided into high-molecular and low-molecular according...
