Embodiment 1

[0273] 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 film of compound 1 was used as a hole injection layer and a hole transport layer. Next, MADN (2-methyl-9,10-bis(naphthalene-2-yl)anthracene): BD01 (1,6-bis(N,Ndiphenylamino)pyrene) was used as the above-mentioned light-emitting layer at 5% doped to produce a thickness of membrane. Next, fabricated as an electron transport layer with a thickness of Alq 3 (Three (8-hydroxyquinoline) aluminum) film, the production thickness is The LiF film and the thickness is An aluminum (Al) film was used to seal (Encapsulate) the element in...

Embodiment 2 to Embodiment 17

[0275] An organic light-emitting device was prepared in the same manner as in Example 1, wherein Compound 2 to Compound 17 were used instead of Compound 1 in the hole injection layer and the hole transport layer, respectively, thereby producing an organic light-emitting device.

Embodiment 18

[0277] 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 hole injection layer on the top of the ITO substrate with a thickness of The 2-TNATA (4,4',4"-tris[2-naphthylphenylamino]triphenylamine) film and the thickness of the hole transport layer are A film of compound 18 synthesized above. Next, CBP (4,4'-bis(N-carbazole)-1,1'-biphenyl):Ir(ppy) 3 doped at 7% while producing a thickness of membrane. Next, fabricated as an electron transport layer with a thickness of After the TPBi (1,3,5-tris(1-phenyl-1H-benzimidazol-2-yl)benzene) film, the thickness is The LiF film and the thickness is An aluminu...

Abstract

The present invention relates to a novel organic compound and, more specifically, to a novel organic compound having a ring closing structure of indole and furan and an arylamine group, and an organic electroluminescent device comprising the same. The organic compound of the present invention has simple charge transfer properties and has high triplet energy and high glass transition temperatures, and thus can provide low driving voltage, high efficiency, low power consumption and long lifespan for an organic electroluminescent device by being used as a hole injection material or a hole transport material.

Description

technical field [0001] The present invention relates to a novel organic compound and an organic light-emitting element comprising the organic compound. More specifically, it relates to an organic light-emitting element having the characteristics of easy charge transfer, high triplet energy and high glass transition temperature ( glass transition temperature) and an organic light-emitting device comprising 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] Generally, an organic light-emitting element has a structure...
