Embodiment 1

[0041] Embodiment 1: the synthesis of compound I-1

[0042]

[0043] In a 250ml three-necked flask, add intermediate Sub-1 (5.15g, 20mmol), intermediate Sub-2 (5.05g, 21.0mmol), three (dibenzylideneacetone) dipalladium (4mol%), tri-tert-butyl Phosphine (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, recrystallized and the crude product obtained was passed through a silica gel column to obtain compound I-1 (12.68 g, yield 80%). LC-MS: M / Z 792.14 (M+H)+.

Embodiment 2

[0044] Embodiment 2: the synthesis of compound II-21

[0045] 1. Synthesis of Intermediate Sub-3

[0046]

[0047] In a 250ml three-necked flask, add intermediate Sub-1 (5.15g, 20mmol), 4-bromotriphenylamine (6.81g, 21.0mmol), three (dibenzylideneacetone) dipalladium (4mol%), tri-tert-butyl Phosphine (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, and the obtained crude product was passed through a silica gel column to obtain compound Sub-3 (7.51 g, yield 75%). LC-MS: M / 500.20 (M+H)+.

[0048] 2. Synthesis of Compound II-21

[0049]

[0050] In a 250ml three-necked flask, add intermediate Sub-4 (10...

Embodiment 3

[0051] Embodiment 3: the synthesis of compound II-31

[0052]

[0053] Compound II-31 was synthesized with reference to the method of Example 2, and other steps were referred to the synthesis of Example 2 to obtain Compound II-31 (7.10 g, yield70%). LC-MS: M / Z 687.24 (M+H)+.

Abstract

The invention relates to an organic compound and an organic light-emitting device using the same, and more specifically relates to a soluble organic compound having excellent color purity and high luminance and light-emitting efficiency, and an OLED device using the same. The structure of the organic compound provided by the invention is shown as a formula 1 in the description. In the structural formula, Ar1 and Ar2 are independently selected from substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C10-C30 condensed ring group, substituted or unsubstituted C8-C30 heteroaryl, substituted or unsubstituted C13-C30 amine derivative or fluorene derivative; and X1 represents carbon (C) or nitrogen (N).

Description

technical field [0001] The present invention relates to an organic compound and an organic light-emitting tube device using the compound, more specifically, a soluble organic compound with excellent color purity, high brightness and luminous efficiency and an OLED device using 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-illumination, low-voltage DC drive, full curing, wide viewing angle, rich colors, etc. 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, elec...
