manufacture example 1-1

[0177] Production Example 1-1: Synthesis of Compound 1-1

[0178]After dissolving 2-bromoindolocarbazole (2-bromo indolocarbazole, 10g, 31mmol) in 50mL of 1,4-dioxane under argon or nitrogen atmosphere, add double pina Alcohol diboron (bis(pinacolato)diboron, 9.52g, 37mmol) and (1,1'-bis(diphenylphosphino)ferrocene)dichloropalladium(II) ((1,1'-bis( diphenyl phosphine) ferrocene) dichloro palladium (II), 0.10 g, 0.12 mmol) and potassium acetate (9.20 g, 94 mmol), and heated at 150° C. for 5 hours to allow convection. After the reaction was completed, water was added to the reaction solution and the mixture was filtered, and then the target compound was extracted with dichloromethane and water and concentrated after removing water. The resulting residue was separated and purified by flash column chromatography using dichloromethane and hexane, and dried in a vacuum oven to obtain the above compound 1-1 (8.48 g, 74%).

manufacture example 1-2

[0179] Production Example 1-2: Synthesis of Compound 1-2

[0180] Compound 1-1 (10 g, 27 mmol), 2,8-dibromodibenzothiophene (Dibromodibenzo thiophene, 13.97 g, 41 mmol), tetrakis (triphenylphosphine) palladium (0) ( Tetrakis (triphenylphosphine) palladium (0), 0.94g, 1mmol) and potassium carbonate (11.29g, 82mmol) were dissolved in 200ml of 1,4-dioxane and 40ml of water, then heated under convection for 24 hours Stir. After the reaction was completed, it was cooled to room temperature and the precipitated crystals were separated by filtration. Next, it was recrystallized using monochlorobenzene and dried in a vacuum oven to obtain the above compound 1-2 (9.49 g, 70%).

Description

technical field [0001] The present invention relates to a novel compound and an organic light-emitting element comprising the novel compound. Background technique [0002] In recent years, self-illuminating organic light-emitting elements that can be driven by low voltages have been compared to liquid crystal displays (LCDs, Liquid crystal displays), which are mainstream flat-panel display elements, because of their excellent viewing angle and contrast, and the need for backlights. It is attracting attention as a next-generation display device due to its features such as ease of thinning, low power consumption, and wide color reproduction range. [0003] Materials used as organic layers in organic light-emitting diodes can be roughly classified into light-emitting layer materials, hole injection materials, hole transport materials, electron transport materials, electron injection materials, and the like according to their functions. In addition, the above-mentioned luminesc...
