Embodiment 1

[0058] Example 1: Synthesis of Compound 1

[0059] 1, synthesis of intermediate 1-1

[0060]

[0061] Intermediates 2-1-2 (25.37 g, 61.4 mm), 9-phenyl-9H-carbazole-3-boric acid (17.63 g, 61.4 mm), four (triphenyl) Base phosphine) palladium (5%), K2CO3 (17.0 g, 122.8 mm), 1,4-dioxane (200 mL) and water (50 ml). The reaction system was tapered to 80 degrees Celsius, and the reaction was reacted under nitrogen for 12 hours. After the reaction was completed, the reaction solution was cooled to room temperature, extracted with o-dichlorobenzene and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and the crude crystalline was obtained from the silica gel column to obtain intermediate 1-1 (24.74 g, yield of 70%). LC-MS: M / Z575.20 (M + H) + .

[0062] 2, the synthesis of Compound 1

[0063]

[0064] Intermediate 1-1 (11.51 g, 20 milligo), A (5.05 g, 21.0 mm), three (dibenzyl acetone) di palladium (4)%), three t-butarten Cylin (8%), potassium t-buto...

Embodiment 2

[0065] Example 2: Synthesis of Compound 13

[0066] 1, synthesis of intermediate 13-1

[0067]

[0068] Intermediates 2-1-2 (8.27 g, 20 mm), iodobenzene (4.28 g, 21.0 mm), three (dibenzyl acetone) diphodium (4 mismone), Trose-butylphosphine (8%), potassium tert-butoxide (3.8 g, 33.6 mm) and o-xylene (80 mL). The reaction system was tapered to 120 degrees Celsius and the reaction was reacted under nitrogen for 12 hours. After the reaction was completed, the reaction liquid was cold until room temperature, and extracted with o-chlorophenyl and water. The organic layer was dried over anhydrous magnesium sulfate, concentrated, and a crude crystalline was obtained from the silica gel column to obtain Compound 13-1 (8.12 g, yield 83%). LC-MS: M / Z488.05 (M + H) + .

[0069] 2, synthesis of intermediate 13-2

The structure of the organic compound provided by the invention is shown as a formula 1 in the specification. In the formula, Ar1, Ar2 and Ar3 are respectively and independently selected from substituted or unsubstituted C1-C30 alkyl, substituted or unsubstituted C6-C30 aryl, substituted or unsubstituted C10-C30 fused ring group, substituted or unsubstituted C4-C30 heteroaryl, substituted or unsubstituted C13-C30 amine derivatives or fluorene derivatives.

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 luminance and high luminous efficiency and an OLED device using the compound. Background technique [0002] With the development of multimedia technology and the improvement of information requirements, the requirements for panel displays have become higher and higher. Among them, OLEDs have a series of advantages such as autonomous, low voltage DC drive, full curing, viewing angle, rich in color, have attracted wide attention in new generation displays and lighting technology, and the application prospects are very broad. The organic electroluminescent device is a spontaneous light-emitting device. The mechanism of OLED luminescence is to migrate from the positive negative two pole injection, and the electron and holes are migrated from the positive negative ...
