Embodiment 1

[0047] Embodiment 1: the synthesis of compound 2-6

[0048] 1. Synthesis of intermediate 2-6-2

[0049]

[0050] Add intermediate phenothiazine borate (19.97 g, 61.4 mmol), 2-6-1 (30.05 g, 61.4 mmol), tetrakis (triphenylphosphine) palladium (5 mole %) in a 500 ml reaction flask ), potassium carbonate (17.0 g, 122.8 mmol), 1,4-dioxane (200 ml) and water (50 ml). The temperature of the reaction system was raised to 80° C., and the reaction was carried out under nitrogen protection for 12 hours. 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 intermediate 2-6-2 (26.12 g, yield 70%). LC-MS: M / Z 607.21(M+H) + .

[0051] 2. Synthesis of compound 2-6

[0052]

[0053] Add intermediate 2-6-2 (12.16 g, 20 mmol), 2-bromo-3-phenylqu...

Embodiment 2

[0054] Embodiment 2: the synthesis of compound 3-2

[0055] Compound 3-2 was synthesized with reference to the method of Example 1 to obtain compound 3-2 (11.22 g, yield 78%). LC-MS: M / Z838.29(M+H) + .

Embodiment 3

[0056] Embodiment 3: the synthesis of compound 3-8

[0057] Compound 2-6 was synthesized with reference to the method of Example 1 to obtain compound 3-8 (14.79 g, yield 87%). LC-MS: M / Z914.32(M+H) + .

Abstract

The invention provides an organic compound and an organic light-emitting device using the same, and particularly relates to a soluble organic compound with excellent color purity, high brightness and high luminous efficiency and an OLED device using the same. The structure of the organic compound provided by the invention is as shown in formula 1 in the specification. In the structural formula, one of R1 and R2 is a substituted or unsubstituted C4-C90 heteroaryl group, heterocyclic group containing nitrogen (N) or amine series group, and the other one is a substituted or unsubstituted C6-C90 heteroaryl group or a heterocyclic group containing two or more nitrogen atoms; and X1 and X2 are independently selected from one of a single bond, sulfur (S), sulfur oxide (SO) or sulfur dioxide (SO2), and at least one of X1 and X2 is not a single bond.

Description

technical field [0001] The present invention relates to an organic compound and an organic light-emitting device using the compound, and more particularly, to a soluble organic compound having excellent color purity and high brightness and high 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-luminescence, low-voltage DC drive, full curing, wide viewing angle, rich colors, etc., and its potential application in the new generation of display and lighting technology has attracted widespread attention, 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 fi...
