Embodiment 1

[0044] Embodiment 1: the synthesis of compound 1-1

[0045] 1. Synthesis of intermediate Sub-1

[0046]

[0047] In the 500mL reaction flask, add intermediate phenylboronic acid (7.49g, 61.4mmol), 2,4-dibromothiazole (17.68g, 61.4mmol), tetrakis (triphenylphosphine) palladium (5mol%), K2CO3 (17.0g , 122.8mmol), 1,4-dioxane (200mL) and water (50mL). The temperature of the reaction system was raised to 80° C., and reacted for 12 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, and extracted with o-dichlorobenzene and water. The organic layer was dried with anhydrous magnesium sulfate, concentrated and recrystallized, and the crude product obtained was passed through a silica gel column to obtain the intermediate Sub-1 (13.13 g, yield 75%). LC-MS: M / Z 283.99 (M+).

[0048] 2. Synthesis of intermediate Sub-4

[0049]

[0050] In a 250ml three-necked flask, add intermediate Sub-3 (3.46g, 10mmo...

Embodiment 2

[0054] Embodiment 2: the synthesis of compound 1-5

[0055] 1. Synthesis of intermediate Sub-5

[0056]

[0057] In a 250ml three-necked flask, add intermediate 2,4-dibromobenzo[4,5]thieno[3,2-d]pyrimidine (3.85g, 11.2mmol), intermediate carbazole (3.0g, 12.3mmol) , tris(dibenzylideneacetone)dipalladium (4 mol%), tri-tert-butylphosphine (8 mol%), potassium tert-butoxide (3.8 g, 33.6 mmol) and o-xylene (80 mL). The temperature of the reaction system was raised to 120° C. and reacted for 12 hours under the protection of nitrogen. After the reaction was completed, the reaction solution was cooled to room temperature, and extracted with o-dichlorobenzene and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and recrystallized to obtain the crude product through a silica gel column to obtain Sub-5 (3.86 g, yield 80%). LC-MS: M / Z 430.32 (M+).

[0058] 2. Synthesis of compound 1-5

[0059]

[0060] Compound 1-5 was synthesized with referenc...

Embodiment 3

[0061] Embodiment 3: the synthesis of compound 1-10

[0062]

[0063] Compound 1-10 was synthesized with reference to the method of Example 1, and other steps were referred to the synthesis of compound 1-1 to obtain compound 1-10 (4.45 g, yield 60%). LC-MS: M / Z 742.31 (M+).

Abstract

The present invention provides an organic compound and an organic electro-luminescent device including the same. The organic compound is represented by Formula 1 below. The organic electro-luminescent device of the present invention has excellent luminous efficiency and lifespan.

Description

technical field [0001] The present invention relates to an organic compound, more specifically, to an organic compound and an organic electroluminescent device comprising the compound. Background technique [0002] With the development of multimedia technology and the improvement of informatization requirements, the performance requirements of panel displays are getting higher and higher. Among them, OLED has a series of advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, and rich colors. It has attracted widespread attention for its potential application in the new generation of display and lighting technologies, and its application prospects are very broad. Organic electroluminescent devices are spontaneous light-emitting devices. The mechanism of OLED light emission is that under the action of an external electric field, electrons and holes are respectively injected from the positive and negative electrodes and then migrate, recomb...
