Problems solved by technology

[0008] However, conventional organic layer materials have advantages in light emitting characteristics, but have a low glass transition temperature and very poor thermal stability, so they cannot achieve a satisfactory level in terms of lifetime of organic electroluminescence elements.

Synthetic example 1

[0173] [Synthesis Example 1] Synthesis of Compound 1

[0174]

[0175] PPY-1 3.0g and (4-(4,6-diphenyl-1,3,5-triazin-2-yl)phenyl)boronic acid 3.4g, tetrakis(triphenylphosphine)palladium(0) 500 mg and 15 ml of a 2M potassium carbonate aqueous solution were added to 60 ml of toluene, 12 ml of ethanol, and 12 ml of water, followed by heating under reflux and stirring for 2 hours. The temperature was lowered to normal temperature, and after the reaction was completed, the potassium phosphate solution was removed, the layers were separated and distilled under reduced pressure, and purified by gel column chromatography (using dichloromethane alone) to produce compound 1 (2.3 g, yield 55%) .

Abstract

The present invention relates to a novel compound and an organic electroluminescent device comprising the same. The compound according to the present invention is employed in an organic layer of an organic electroluminescent device, preferably in a light-emitting layer, an emission auxiliary layer, an electron transport auxiliary layer or an electron transport layer, thus improving the emission efficiency, driving voltage, lifespan, etc. in the organic electroluminescent device.

Description

technical field [0001] The present invention relates to a novel organic compound and an organic electroluminescence device using the same, and more preferably, a compound having excellent electron transport ability and luminescence ability and its addition to one or more organic layers to improve luminous efficiency, driving voltage, and lifetime. Organic electroluminescent elements with improved characteristics. Background technique [0002] Starting from Bernanose's observation of organic thin film luminescence in the 1950s, research on the organic electroluminescent device developed by using the blue electroluminescence of anthracene single crystals in 1965 was carried out, and then in 1987 by Tang (Tang) proposed an organic electroluminescent element with a laminated structure divided into two functional layers, a hole layer and a light emitting layer. Afterwards, in order to manufacture high-efficiency and long-life organic electroluminescent elements, the form of intr...
