Embodiment 1

[0237] Ultrasonic cleaning with distilled water has a thickness of Indium Tin Oxide (ITO) thin film glass substrate. After cleaning with distilled water, use solvents such as isopropanol, acetone, and methanol to perform ultrasonic cleaning and dry, then transport to a plasma cleaner and use oxygen plasma to clean the above-mentioned substrate for 5 minutes, and then use thermal vacuum evaporation The thermal evaporator made a thickness of The HATCN film as the hole injection layer and the thickness is HT01 film as a hole transport layer. Next, a film with a thickness of The film is used as a buffer layer and is doped with BH01:BD01 at 5% to make a thickness of film as the above-mentioned light-emitting layer.

[0238] Next, with Alq 3 (Tris(8-hydroxyquinoline)aluminum): Liq=1:1 to produce a thickness of After the film was used as the electron transport layer, a thickness of The LiF film and the thickness is An aluminum (Al) film was used to seal (Encapsulat...

Embodiment 2 to 13

[0240] Compounds 2 to 13 were used instead of Compound 1, and a buffer layer film was fabricated in the same manner as in Example 1, thereby fabricating an organic light-emitting device.

Embodiment 14

[0244] Ultrasonic cleaning with distilled water has a thickness of Indium Tin Oxide (ITO) thin film glass substrate. After cleaning with distilled water, use solvents such as isopropanol, acetone, and methanol to perform ultrasonic cleaning and dry, then transport to a plasma cleaner and use oxygen plasma to clean the above-mentioned substrate for 5 minutes, and then use thermal vacuum evaporation The thermal evaporator made a thickness of The HATCN film as the hole injection layer and the thickness is HT01 film as a hole transport layer. Next, a film with a thickness of The film as a buffer layer and compound 14: Ir(ppy) 3 (Tris(2-phenylpyridine)iridium) was doped at 9% to produce a thickness of film as the above-mentioned light-emitting layer. Next, with Alq 3 (Tris(8-hydroxyquinoline)aluminum): Liq=1:1 to produce a thickness of After the film was used as the electron transport layer, a thickness of The LiF film and the thickness is An aluminum (Al) film ...

Abstract

The present invention relates to a novel organic compound, and more specifically, relates to a novel organic compound comprising two or more ring closing structures of indole and furan and an organic light-emitting device comprising the organic compound. Due to the characteristics of easy transfer of charges, high triplet energy and high glass transition temperature, the organic compound is especially used as a hole injection material, a hole transport material or a light-emitting layer material, which can give an organic light-emitting element a low Features of driving voltage, high efficiency, low power consumption, and long service life.

Description

technical field [0001] The present invention relates to a novel organic compound, and more specifically, relates to a novel organic compound having the characteristics of easy charge transfer, high triplet energy and high glass transition temperature and An organic light-emitting device containing the organic compound. Background technique [0002] Recently, self-luminous organic light-emitting elements that can be driven at low voltages have excellent viewing angles and contrast ratios compared with liquid crystal displays (LCDs), which are the mainstream of flat-panel display elements, and require no backlight. Quantization and thinning are also advantageous in terms of power consumption and a wide range of color reproduction, so they are attracting attention as next-generation display elements. [0003] In general, an organic light emitting element has a structure including an organic layer between a cathode (electron injection electrode) and an anode (hole injection ele...
