Abstract

A compound represented by following formula (24): wherein R 11 and R 12 each represents a substituent; m 1 represents an integer of from 0 to 4; m 2 represents an integer of from 0 to 6; Z 2 represents an atomic group which forms an aryl ring or a heteroaryl ring; Z 3 represents an atomic group which forms a nitrogen-containing heteroaryl ring; and n 1 represents an integer of from 1 to 3.

Claims (18)

1. A compound represented by following formula (24):

wherein R 11 and R 12 each represents a substituent; m 1 represents an integer of from 0 to 4; m 2 represents an integer of from 0 to 6; Z 2 represents an atomic group which forms an aryl ring or a heteroaryl ring; Z 3 represents an atomic group which forms a nitrogen-containing heteroaryl ring; and n 1 represents an integer of from 1 to 3.

2. The compound according to claim 1 , wherein m 1 or m 2 is plural, and one of the plurality of R 11 s is connected to another of the plurality of R 11 s to form a cyclic structure, or one of the plurality of R 12 s is connected to another of the plurality of R 12 s to form a cyclic structure, or one of the plurality of R 11 s is connected to one of the plurality of R 12 s to form a cyclic structure.

3. The compound according to claim 1 , wherein R 11 and R 12 each represents an alkyl group, an aryl group, a heteroaryl group, an alkoxy group, a halogen atom, a cyano group or a cyclic structure obtained by the connection of one of the plurality of R 11 s to another of the plurality of R 11 s, or one of the plurality of R 12 s to another of the plurality of R 12 s, or one of the plurality of R 11 s to one of the plurality of R 12 s.

4. The compound according to claim 1 , wherein R 11 and R 12 each represents an alkyl group, an aryl group or groups which are connected to each other to form an aromatic group.

5. The compound according to claim 1 , wherein Z 2 represents an atomic group which forms an aryl ring having from 6 to 30 carbon atoms or a 5- or 6-membered heteroaryl ring.

6. The compound according to claim 1 , wherein Z 3 represents a 5- or 6-membered nitrogen-containing heteroaryl ring.

7. The compound according to claim 1 , wherein m 1 represents an integer of from 0 to 2.

8. The compound according to claim 1 , wherein m 2 represents an integer of from 0 to 2.

9. The compound according to claim 1 , wherein a quinoline derivative ligand in the compound represented by formula (24) is formed by at least four rings.

10. The compound according to claim 1 , which is represented by following formula (2-15):

11. A product comprising the compound according to claim 1 , which is used as fluorescent brightening agent, photographic material, UV-absorbing material, laser dye, color filter dye or color conversion filter.

12. The product according to claim 11 , wherein the product is a fluorescent brightening agent.

13. The product according to claim 11 , wherein the product is a photographic material.

14. The product according to claim 11 , wherein the product is a UV-absorbing material.

15. The product according to claim 11 , wherein the product is a laser dye.

16. The product according to claim 11 , wherein the product is a color filter dye.

17. The product according to claim 11 , wherein the product is a color conversion filter.
