Synthetic example 1
[0222] Synthesis Example 1: Synthesis of 4-(biphenyl-2-yloxy)-3,5,6-trichloro-phthalonitrile
[0223]5 g of 3,4,5,6-tetrachlorophthalonitrile, 3.21 g of 2-phenylphenol, 3.9 g 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 completed, the resultant was filtered and washed with acetone, and the liquid obtained therefrom was distilled to obtain a solid. Here, the obtained solid was dissolved in a small amount of dichloromethane, and then washed several times with hexane, filtered and dried in vacuo 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 g of 3,4,5,6-tetrachlorophthalonitrile, 3.06 g of 2,6-dichlorophenol, 3.9 g 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 completed, the resultant was filtered and washed with acetone, and the liquid obtained therefrom was distilled to obtain a solid. Here, the obtained solid was dissolved in a small amount of dichloromethane, and then washed several times with hexane, filtered and dried in vacuo 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 g of 3,4,5,6-tetrachlorophthalonitrile, 4.75 g of 2,6-dibromophenol, 3.9 g 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 present invention provides a compound represented by Chemical Formula 1, a photosensitive resin composition including the same, and a color filter manufactured using the photosensitive resin composition. In Chemical Formula 1, each substituent is the same as defined in the specification. The compound represented by Chemical Formula 1 has excellent green spectral characteristics, a high molarextinction coefficient, and excellent solubility in organic solvents, and thus can be used as a dye for a green photosensitive resin composition for a color filter, and therefore, contains Dye-based color filters can have excellent color strength, transmittance, brightness, and contrast ratio. [chemical formula 1]
Description
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2016-0075318 filed with the Korean Intellectual Property Office on June 16, 2016 and Korean Patent Application No. 10 filed with the Korean Intellectual Property Office on January 9, 2017 - The benefit of No. 2017-0003109, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a novel compound, a photosensitive resin composition including the same, and a color filter.
