Embodiment 1

[0046] Embodiment 1: the synthesis of compound III-7

[0047] 1. Synthesis of intermediate Sub-1

[0048]

[0049]In a 500mL reaction flask, add intermediate Sub-0 (20.45g, 61.4mmol), 1-iodo-2-nitrobenzene (15.29g, 61.4mmol), tetrakis (triphenylphosphine) palladium (5mol%), K2CO3 (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 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 obtained crude product was passed through a silica gel column to obtain an intermediate Sub-1 (15.11 g, yield 75%). LC-MS: M / Z 326.99 (M+H) + .

[0050] 2. Synthesis of intermediate Sub-2

[0051]

[0052] In a 250ml reaction flask, add Sub-1 (0.33g, 0.98mmol), triethyl phosph...

Embodiment 2

[0067] Embodiment 2: the synthesis of compound III-61

[0068]

[0069] Compound III-61 was synthesized with reference to the method of Example 1, and other steps were referred to the synthesis of compound III-7 to obtain compound III-61 (8.71 g, yield 75%). LC-MS: M / Z 869.35(M+H) + .

Embodiment 3

[0070] Embodiment 3: the synthesis of compound III-102

[0071]

[0072] Compound III-102 was synthesized with reference to the method of Example 1, and the synthesis of compound III-7 was referred to for other steps to obtain compound III-102 (7.76 g, yield 72%). LC-MS: M / Z870.31(M+H) + .

Abstract

The invention relates to an organic compound and an organic light-emitting device using the same, and 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 Z represents a substituted or unsubstituted naphthalene derivative.

Description

technical field [0001] The 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-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...
