Abstract

A compound represented by specific chemical formula, a core including the same, a core-shell dye including a shell surrounding the core, a photosensitive resin composition including the same, and a color filter manufactured using the photosensitive resin composition are disclosed.

First claim

What is claimed is:

1. A compound represented by Chemical Formula 1:

wherein, in Chemical Formula 1,
R 1 is a substituted or unsubstituted C3 to C20 cycloalkyl group or represented by Chemical Formula 2, and
R 2 is a substituted C6 to C20 aryl group,

wherein, in Chemical Formula 2,
R 3 and R 4 are independently a substituted or unsubstituted C1 to C10 alkyl group.

2. The compound of claim 1 , wherein R 2 is a C6 to C20 aryl group substituted with a C1 to C10 alkyl group.

3. The compound of claim 2 , wherein R 2 is represented by Chemical Formula 3:

wherein, in Chemical Formula 3,
R 5 and R 6 are independently a C1 to C7 alkyl group.

4. The compound of claim 1 , wherein the compound represented by Chemical Formula 1 is represented by one selected from compounds represented by Chemical Formula 1-1 to Chemical Formula 1-7

5. A core-shell dye comprising
a core including the compound of claim 1 ; and
a shell surrounding the core.

6. The core-shell dye of claim 5 , wherein the shell is represented by Chemical Formula 4 or Chemical Formula 5:

wherein, in Chemical Formula 4 and Chemical Formula 5,
L a to L d are independently a single bond or a substituted or unsubstituted C1 to C10 alkylene group.

7. The core-shell dye of claim 6 , wherein the L a to L d are independently a substituted or unsubstituted C1 to C10 alkylene group.

8. The core-shell dye of claim 5 , wherein the shell is represented by Chemical Formula 4-1 or Chemical Formula 5-1:

9. The core-shell dye of claim 8 , wherein the shell has a cage width of 6.5 Å to 7.5 Å.

10. The core-shell dye of claim 5 , wherein the core has a length of 1 nm to 3 nm.

11. The core-shell dye of claim 5 , wherein the core has a maximum absorption peak in a wavelength of 530 nm to 680 nm.

12. The core-shell dye of claim 5 , wherein the core-shell dye is selected from compounds represented by Chemical Formula 6 to Chemical Formula 19:

13. The core-shell dye of claim 5 , wherein the core-shell dye includes the core and the shell in a mole ratio of 1:1.

14. The core-shell dye of claim 5 , wherein the core-shell dye is a green dye.

15. A photosensitive resin composition comprising
the compound of claim 1 .

16. The photosensitive resin composition of claim 15 , wherein the photosensitive resin composition further includes a binder resin, a photopolymerizable monomer, a photopolymerization initiator, and a solvent.

17. The photosensitive resin composition of claim 16 , wherein the photosensitive resin composition further includes a pigment.

18. The photosensitive resin composition of claim 16 , wherein the photosensitive resin composition includes
0.5 wt % to 10 wt % of the compound;
0.1 wt % to 30 wt % of the binder resin;
0.1 wt % to 30 wt % of the photopolymerizable monomer;
0.1 wt % to 5 wt % of the photopolymerization initiator; and
a balance amount of the solvent based on a total amount of the photosensitive resin composition.

19. The photosensitive resin composition of claim 16 , wherein the photosensitive resin composition further includes malonic acid, 3-amino-1,2-propanediol, a silane-based coupling agent including a vinyl group or a (meth)acryloxy group, a leveling agent, a surfactant, a radical polymerization initiator, or a combination thereof.

20. A color filter manufactured using the photosensitive resin composition of claim 15 .
