preparation example 1

[0179] Preparation Example 1. Preparation of Compound A

[0180]

[0181] To phenylimidazole (3.86 g, 20 mmol) was added 100 ml of dimethylformamide (DMF), to which sodium hydride (1 g, 21 mmol) was slowly added at room temperature, and the resulting mixture was stirred until no hydrogen gas was generated. Thereafter, benzyl chloride (2.5 g, 20 mmol) was added thereto, and the resulting mixture was stirred at room temperature. After the reaction was terminated, distilled water was added thereto, extraction was performed with toluene, and the organic layer was dried over sodium sulfate and dried under reduced pressure. The obtained product was purified with a column (ethyl acetate:hexane ratio=1:40) to obtain compound A (3.2 g, yield 56%).

preparation example 2

[0182] Preparation Example 2. Preparation of Compound B

[0183]

[0184] To phenylimidazole (1.93 g, 10 mmol) was added 50 ml of dimethylformamide (DMF), to which sodium hydride (0.5 g, 10.5 mmol) was slowly added at room temperature, and the resulting mixture was stirred until no hydrogen gas was generated. Thereafter, propyl iodide (2.0 g, 12 mmol) was added thereto, and the resulting mixture was stirred at room temperature. After the reaction was terminated, distilled water was added thereto, extraction was performed with toluene, and the organic layer was dried over sodium sulfate and dried under reduced pressure. The obtained product was purified with a column (ethyl acetate:hexane ratio=1:30) to obtain compound B (1.6 g, yield 64%).

preparation example 3

[0185] Preparation Example 3. Preparation of Compound C

[0186]

[0187] 4,4-Difluorobenzophenone (15 g, 69 mmol) and 2-ethylaminoethanol (50 g, 552 mmol) were placed in a flask under a nitrogen atmosphere, and the resulting mixture was heated and refluxed at 150 °C for 48 h . After the reaction was terminated, distilled water was added thereto, extraction was performed with dichloromethane, and the organic layer was dried over sodium sulfate and dried under reduced pressure. Ethyl acetate was put into the obtained product, and the obtained product was stirred at room temperature for 2 hours, and then filtered to obtain light yellow powder Compound C (19 g, yield 77%).

Abstract

The present invention relates to a novel compound, a coloring material composition containing the same, and a resin composition containing the same.

Description

technical field [0001] This application claims priority and benefit from Korean Patent Application No. 10-2016-0015691 filed with the Korean Intellectual Property Office on February 11, 2016, the entire contents of which are incorporated herein by reference. [0002] This specification relates to a novel compound, a colorant composition containing the same, and a resin composition containing the same. Background technique [0003] Recently, as a light source of a liquid crystal display (LCD), devices such as LEDs or OLEDs and QDs are often used instead of existing CCFLs. However, in order to manufacture thin film displays, flexible displays, etc., display products in which color filters are removed, that is, display products that emit light using, for example, LEDs or OLEDs and QDs as unit pixels, have been developed and produced. [0004] However, in the case of a display using LED, OLED, QD, etc. as a unit pixel, it is difficult to increase the area of ​​the display, and ...
