Synthetic example 1

[0280] (Synthesis Example 1: Synthesis of Intermediate A)

[0281]

[0282] Added aniline (10mol), 4-bromotoluene (10mol), Pd 2 (dba) 3 (0.1 mol) and Xphos (0.1 mol), and the mixture was heated and stirred at 100°C for 24 hours. To this solution was added ethyl acetate, and the obtained mixture was washed twice with water to extract an organic layer. The extracted organic layer was distilled under reduced pressure and purified by column chromatography to obtain Intermediate A.

Synthetic example 2

[0283] (Synthesis Example 2: Synthesis of Intermediate B-1)

[0284]

[0285] Added 2,4-dimethyldiphenylamine (10mol), 1,2-epoxyhexane (12mol) and sodium hydride (12mol) to N,N-dimethylformamide, and at 90°C The mixture was heated and stirred for 24 hours. To this solution was added ethyl acetate, and the obtained mixture was washed twice with water to extract an organic layer. The extracted organic layer was distilled under reduced pressure and separated by column chromatography to obtain Intermediate B-1.

Synthetic example 3

[0286] (Synthesis Example 3: Synthesis of Intermediate B-2)

[0287]

[0288] Intermediate B-2 was synthesized in the same manner as in Synthesis Example 2 except that 1,2-epoxybutylene was used instead of 1,2-epoxyhexane.

Abstract

The present invention discloses a compound represented by the chemical formula (1), and a core-shell dye; and a photosensitive resin composition containing the compound represented by the chemical formula (1) or the core-shell dye, and a color filter manufactured using the photosensitive resin composition. The core-shell dye includes a core comprising the compound represented by the chemical formula (1); and a shell surrounding the core. The color filter containing the compound or the core-shell dye has improved brightness and contracst. [Chemical Formula 1] (wherein each substituent is as defined in the specification).

Description

technical field [0001] The present invention relates to a novel compound, a core-shell dye, a photosensitive resin composition comprising the novel compound or the core-shell dye, and a color filter manufactured using the photosensitive resin composition. Background technique [0002] Among various types of displays, liquid crystal display devices have the advantages of lightness, thinness, low cost, low operating power consumption, and high support for integrated circuits, and have been more widely used in laptop computers, monitors, and television screens . The liquid crystal display device includes a lower substrate and an upper substrate. A black matrix, a color filter, and an indium tin oxide pixel electrode are formed on the lower substrate, and a liquid crystal layer, a thin film transistor, and a capacitor layer are formed on the upper substrate. active circuit parts and indium tin oxide pixel electrodes. In the pixel area, each pixel is formed by sequentially stac...
