Example Embodiment

[0173] Synthesis Example 1-1: Synthesis of 3,4,6-trichloro-5-(4-methoxy-2-methyl-phenoxy)-phthalonitrile

[0174] Combine 3,4,5,6-tetrachlorophthalonitrile (3,4,5,6-tetrachlorophthalonitrile) (5g), 4-methoxy-2-methylphenol ) (3.12g), K 2 CO 3 (3.9 g) and N,N-dimethylformamide (25 ml) were placed in a 100 ml flask and then heated at 70°C while stirring. When the reaction is complete, EA (ethyl acetate) is used for extraction. After extraction, a solid was obtained by concentration. In this article, the obtained solid was dissolved in a small amount of dichloromethane, washed several times with hexane, filtered and dried in vacuum to obtain 3,4,6-trichloro-5-(4-methoxy-2- Methyl-phenoxy)-phthalonitrile.

[0175] Synthesis Example 1-2: Synthesis of 4-(2-tert-butyl-4-methoxy-phenoxy)-3,5,6-trichloro-phthalonitrile

[0176] Combine 3,4,5,6-tetrachlorophthalonitrile (5g), 2-tert-butyl-4-methoxyphenol (4.07g), K 2 CO 3 (3.9 g), N,N-dimethylformamide (25 mL) was placed in a 100 mL flask and then heated at 70°C while stirring. When the reaction was completed, EA (ethyl acetate) was used for extraction. After extraction, a solid was obtained by concentration. In this article, the obtained solid was dissolved in a small amount of dichloromethane, washed several times with hexane, filtered and dried in vacuum to obtain 4-(2-tert-butyl-4-methoxy-phenoxy)- 3,5,6-Trichloro-phthalonitrile.

[0177] Synthesis Example 1: Synthesis of a compound represented by Chemical Formula 4

[0178] 3,4,6-trichloro-5-(4-methoxy-2-methyl-phenoxy)-phthalonitrile (2g), 1,8- Diazabicycloundec-7-ene (1.04 g) and 1-pentenol (10 g) were placed in a 100 ml flask, and then heated at 90°C to dissolve the solids, and zinc acetate (0.25 g) Added thereto, and the mixture was heated at 140°C while stirring. When the reaction is complete, the precipitate is confirmed by methanol, filtered, and dried under vacuum. The dried solid is purified by column chromatography. After purification, dichloromethane was appropriately added to the obtained solid to dissolve it, and methanol was added thereto for crystallization. The crystalline solid was filtered and vacuum dried to obtain the compound represented by Chemical Formula 4.

Abstract

The present invention discloses a compound represented by chemical formula 1 and a photosensitive resin composition comprising the same, and a color filter produced using the photosensitive resin composition. In chemical formula 1, each substituent is the same as defined in the specification. The compound disclosed herein has excellent green spectral characteristics, high molar extinction coefficients, and excellent solubility in organic solvents.

Description

technical field [0001] The present disclosure relates to a novel compound, a photosensitive resin composition and a color filter containing the same. Background technique [0002] A color filter manufactured by using a pigment-type photosensitive resin composition has limitations in brightness and contrast ratio due to the particle size of the pigment. In addition, color imaging devices for image sensors require smaller dispersed particle sizes to form fine patterns. In response to such needs, attempts have been made to provide color filters with improved color characteristics such as brightness and contrast ratio by preparing photosensitive resin compositions containing non-particle-forming dyes instead of pigment. [0003] Therefore, it is necessary to study a compound suitable as a dye of a photosensitive resin composition. Contents of the invention [0004] One embodiment provides a novel compound. [0005] Another embodiment provides a photosensitive resin composi...
