Synthetic example 1

[0109] Synthesis Example 1: Synthesis of Compound 8

[0110]

[0111] Starting material 1-A (17.1 g, 50 mmol), starting material 1-B (13.6 g, 55 mmol), tetrakis(triphenylphosphine) palladium (1.7 g, 1.5 mmol), potassium carbonate (20.7 g, 150 mmol) were charged After entering the 2,000ml flask, add toluene (500ml), ethanol (100ml), H 2 O (100ml). Make N while stirring at room temperature 2 After 30 minutes of bubbling, the temperature was raised and stirring reflux was performed for 6 hours.

[0112] After cooling to room temperature, the reactant was added to methanol (1,000 ml), and the resulting precipitate was filtered. Column chromatography was performed using dichloromethane and n-hexane as developing solvents to obtain Compound 8 (15.1 g, 65%).

Synthetic example 2

[0114] Synthesis Example 2: Synthesis of Compound 9

[0115]

[0116] Compound 9 (18.2 g, 70%) was obtained in the same manner as in Synthesis Example 1 except that starting material 2-B (13.6 g, 55 mmol) was used instead of starting material 1-B.

[0117] MS (MALDI-TOF) m / z: 464 [M] +

Synthetic example 3

[0118] Synthesis Example 3: Synthesis of Compound 11

[0119]

[0120] Compound 11 (16.8 g, 62%) was obtained in the same manner as in Synthesis Example 1 except that starting material 3-B (17.8 g, 55 mmol) was used instead of starting material 1-B.

Abstract

The present invention provides an organic compound and an organic electroluminescence element including the same. The compound is represented by the following Chemical Formula 1, wherein R1 to R5 arethe same or different from each other, and are each independently selected from hydrogen, deuterium, cyano, etc.; one or more of R6 to R13 is deuterium, the rest being each independently selected fromhydrogen, deuterium, cyano, etc.; L is selected from substituted or unsubstituted arylene groups having 6 to 30 carbon atoms, etc.; Ar1 is selected from substituted or unsubstituted alkyl groups having 1 to 30 carbon atoms; and the substituents of R1 to R13, the L, and the Ar1 may be each independently substituted with a substituent selected from hydrogen, deuterium, cyano, etc.. When a pluralityof substituents exists, the substitutes are same or different from each other. The compound of the present invention has excellent chemical stability as a novel anthracene-based host material that can be used in an organic electroluminescence element, and the organic electroluminescence element including the compound has a low driving voltage and particularly excellent lifetime. The chemical formula 1 is shown in the specification.

Description

technical field [0001] The present invention relates to a novel organic compound and an organic electroluminescent element comprising the same, more specifically, to an anthracene-based organic compound and a material comprising the same as one or more organic layers with low driving voltage, long life, and high luminous efficiency. Organic electroluminescent elements with excellent characteristics. Background technique [0002] Compared with other flat-panel display elements such as conventional liquid crystal display (LCD), plasma display panel (PDP) and field emission display (FED), organic electroluminescent elements have the advantages of simple structure, diverse manufacturing processes, and high brightness. And viewing angle characteristics are excellent, the response speed is fast, and the driving voltage is low, so it is being actively developed for use as a light source for flat panel displays such as wall-mounted TVs or displays, lighting, and advertising boards. ...
