Abstract

A compound represented by Chemical Formula 1, a photosensitive resin composition including the same, and a color filter manufactured using the photosensitive resin composition are provided.

In Chemical Formula 1, each substituent is the same as defined in the specification.

First claim

What is claimed is:

1. A compound represented by Chemical Formula 1:

wherein, in Chemical Formula 1, R 1 to R 16 are independently a hydrogen atom, a halogen atom, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 alkoxy group, a substituted or unsubstituted C6 to C20 aryl group, or a substituted or unsubstituted C6 to C20 aryloxy group, provided that:
at least one of R 1 to R 16 is represented by Chemical Formula 2, and
at least one of R 1 to R 16 is represented by Chemical Formula 4,

wherein in Chemical Formula 2,
R 17 and R 18 are independently a halogen atom, and
n1 and n2 are independently an integer ranging from 0 to 5, provided that 1≤n1+n2≤5,

2. The compound as claimed in claim 1 , wherein Chemical Formula 2 is represented by one selected from Chemical Formula 3-1 to Chemical Formula 3-4:

wherein in Chemical Formulae 3-1 to 3-4,
R 17 and R 18 are independently a halogen atom.

3. The compound as claimed in claim 1 , wherein:
at least one of R 1 to R 4 is represented by Chemical Formula 2,
at least one of R 5 to R 8 is represented by Chemical Formula 4,

at least one of R 13 to R 16 is represented by Chemical Formula 4.

4. The compound as claimed in claim 1 , wherein:
at least one of R 1 to R 4 is represented by Chemical Formula 2,
at least one of R 5 to R 8 is represented by Chemical Formula 2,
at least one of R 9 to R 12 is represented by Chemical Formula 4, and
at least one of the R 13 to R 16 is represented by Chemical Formula 4.

5. The compound as claimed in claim 1 , wherein:
at least one of R 1 to R 4 is represented by Chemical Formula 2,
at least one of R 5 to R 8 is represented by Chemical Formula 4,
at least one of R 9 to R 12 is represented by Chemical Formula 2, and
at least one of R 13 to R 16 is represented by Chemical Formula 4.

6. The compound as claimed in claim 1 , wherein:
at least one of R 1 to R 4 is represented by Chemical Formula 2,
at least one of R 5 to R 8 is represented by Chemical Formula 2,
at least one of R 9 to R 12 is represented by Chemical Formula 2, and
at least one of R 13 to R 16 is represented by Chemical Formula 4.

7. The compound as claimed in claim 1 , wherein the compound represented by Chemical Formula 1 is represented by one of the following Chemical Formulae:

8. The compound as claimed in claim 1 , wherein the compound is a green dye.

9. The compound as claimed in claim 8 , wherein the green dye has maximum transmittance in a 445 nm to 560 nm wavelength range.

10. A photosensitive resin composition comprising the compound as claimed in claim 1 .

11. The photosensitive resin composition as claimed in claim 10 , wherein the photosensitive resin composition includes about 1 wt % to about 10 wt % of the compound based on a total amount of the photosensitive resin composition.

12. The photosensitive resin composition as claimed in claim 10 , wherein the photosensitive resin composition further includes a binder resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent.

13. The photosensitive resin composition as claimed in claim 10 , wherein the photosensitive resin composition further includes a pigment.

14. The photosensitive resin composition as claimed in claim 13 , wherein the pigment includes a yellow pigment, a green pigment, or a combination thereof.

15. A color filter manufactured using the photosensitive resin composition as claimed in claim 10 .

16. A color filter comprising the compound as claimed in claim 1 .

17. An electronic device comprising a display having a color filter, the color filter including the compound as claimed in claim 1 .
