Embodiment 1

[0140] Example 1: Synthesis of Compound 1

[0141]

[0142] In a round bottom flask, 3.0 g of Intermediate A and 3.4 g of (10-phenylanthracene-9-yl)boronic acid were dissolved in 100 ml of toluene, and 15 ml of K was added. 2 CO 3 (2M) and 0.33g of Pd(PPh 3 ) 4 , And then reflux and stir. The reaction was confirmed by TLC, and if the reaction was completed, water was added, and then 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] Example 2: Synthesis of Compound 2

[0144]

[0145] In a round bottom flask, 3.0g of Intermediate A and 4.0g of (10-(naphthalene-2-yl)anthracene-9-yl)boronic acid were dissolved in 105ml of toluene, and 15ml of K was added. 2 CO 3 (2M) and 0.33g of Pd(PPh 3 ) 4 , And then reflux and stir. The reaction was confirmed by TLC, and if the reaction was completed, water was added, and then 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] Example 3: Synthesis of Compound 3

[0147]

[0148] In a round bottom flask, 3.0 g of Intermediate A and 4.0 g of (10-(naphthalene-1-yl)anthracene-9-yl) boric acid were dissolved in 105 ml of toluene, and 15 ml of K was added. 2 CO 3 (2M) and 0.33g of Pd(PPh 3 ) 4 , And then reflux and stir. The reaction was confirmed by TLC, and if the reaction was completed, water was added, and then 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

The organic light-emitting compound of the present invention can exhibit excellent device characteristics when applied to organic light-emitting devices due to its excellent hole and electron transport properties, blue luminescence maintenance and luminous efficiency, high color purity, high efficiency and long life.

Description

Technical field [0001] The present invention relates to a novel light-emitting compound and an organic light-emitting element containing the same. Background technique [0002] Recently, self-luminous organic light-emitting elements that can be driven at a low voltage have superior viewing angles, contrast, etc., compared with liquid crystal displays (LCDs), which are mainstream flat-panel display elements. The volume and thinness are also advantageous in terms of power consumption, and the color reproduction range is wide, so they are attracting attention as the next-generation display device. [0003] The materials used as the organic layer in organic light-emitting elements 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 luminescent materials can be divided into macromolecules and low molecules ac...
