Synthetic example 1

[0222] Synthesis Example 1: Synthesis of 4-(biphenyl-2-yloxy)-3,5,6-trichloro-phthalonitrile

[0223]5 grams of 3,4,5,6-tetrachlorophthalonitrile, 3.21 grams of 2-phenylphenol, 3.9 grams of K 2 CO 3 And 25 ml of acetone were placed in a 100 ml flask, and then stirred while heating at 70°C. When the reaction was complete, the resultant was filtered and washed with acetone, and the liquid obtained therefrom was distilled to obtain a solid. Herein, the obtained solid was dissolved in a small amount of dichloromethane, and then washed several times with hexane, filtered and dried under vacuum to obtain 4-(biphenyl-2-yloxy)-3,5,6 - Trichloro-phthalonitrile.

Synthetic example 2

[0224] Synthesis Example 2: Synthesis of 3,4,6-trichloro-5-(2,6-dichloro-phenoxy)-phthalonitrile

[0225] 5 grams of 3,4,5,6-tetrachlorophthalonitrile, 3.06 grams of 2,6-dichlorophenol, 3.9 grams of K 2 CO 3 And 25 ml of acetone were placed in a 100 ml flask, and then stirred while heating at 70°C. When the reaction was complete, the resultant was filtered and washed with acetone, and the liquid obtained therefrom was distilled to obtain a solid. Herein, the obtained solid was dissolved in a small amount of dichloromethane, and then washed several times with hexane, filtered and dried under vacuum to obtain 3,4,6-trichloro-5-(2,6-dichloro -phenoxy)-phthalonitrile.

Synthetic example 3

[0226] Synthesis Example 3: Synthesis of 3,4,6-trichloro-5-(2,6-dibromo-phenoxy)-phthalonitrile

[0227] 5 grams of 3,4,5,6-tetrachlorophthalonitrile, 4.75 grams of 2,6-dibromophenol, 3.9 grams of K 2 CO 3 and 25 ml of N,N-dimethylformamide were placed in a 100 ml flask, and stirred while heating at 70°C. When the reaction was complete, EA (ethyl acetate) was used for extraction. After extraction, the resultant was concentrated to obtain a solid. The obtained solid was dissolved in a small amount of dichloromethane, washed several times with hexane, filtered and dried in vacuo to obtain 3,4,6-trichloro-5-(2,6-dibromo-phenoxy)- Phthalonitrile.

Abstract

The invention provides a compound represented by chemical formula 1, a photosensitive resin thereof, and a color filter manufactured using the photosensitive resin composition. In chemical formula 1, each substituent is the same as defined in the specification.Compounds represented by formula 1 have excellent green spectral properties, high molar extinction coefficients, and excellent solubility in organic solvents, and therefore can be used for dyes that act on the green-sensitive resin composition of the color filter, and therefore the color filter containing the dye can have excellent color intensity, transmittance, brightness, and contrast ratio.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2016-0075318 filed in KIPO on Jun. 16, 2016 and Korean Patent Application No. 10 filed in KIPO on Jan. 9, 2017 - The rights and interests of No. 2017-0003109, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a novel compound, a photosensitive resin composition including the same, and a color filter. Background technique [0004] Among many types of displays, liquid crystal display devices have advantages in brightness, thinness, low cost, low operating power consumption, and improved adhesion to integrated circuits, and have been more widely used in notebook computers, monitors, and TV screens . The liquid crystal display device comprises a lower substrate on which a black matrix, a color filter, and an ITO pixel electrode are formed; and an upper substrate on which an...
