Abstract

An organic compound that emits red light having a long wavelength is represented by formula (1). In formula (1), R1 to R24 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a silyl group, and a cyano group.

First claim

What is claimed is:

1. An organic compound represented by formula (1):

wherein R 1 to R 24 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a silyl group, and a cyano group.

2. The organic compound according to claim 1 , wherein at least one of R 1 to R 24 in formula (1) is a phenyl group, and the phenyl group has a substituent at an ortho position of the phenyl group.

3. The organic compound according to claim 1 , wherein at least two of R 13 , R 14 , R 19 , and R 20 in formula (1) are each the substituted or unsubstituted aryl group.

4. The organic compound according to claim 1 , wherein at least one of R 13 and R 14 , at least one of R 19 and R 20 , and R 8 in formula (1) are each the substituted or unsubstituted aryl group.

5. The organic compound according to claim 1 ,
wherein at least two of R 13 , R 14 , R 19 , and R 20 in formula (1) are each a phenyl group,
the phenyl group has a substituent at least at an ortho position of the phenyl group, and
the substituent is selected from the group consisting of a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, and a cyano group.

6. The organic compound according to claim 5 ,
wherein at least one of R 13 and R 14 and at least one of R 19 and R 20 are each a phenyl group,
the phenyl group has a substituent at least at an ortho position of the phenyl group, and
the substituent is selected from the group consisting of a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, and a cyano group.

7. An organic light-emitting element comprising:
a pair of electrodes; and
an organic compound layer disposed between the pair of electrodes,
wherein the organic compound layer includes the organic compound according to claim 1 .

8. The organic light-emitting element according to claim 7 , wherein the organic compound layer includes a light-emitting layer.

9. The organic light-emitting element according to claim 8 , wherein the organic light-emitting element emits red light.

10. The organic light-emitting element according to claim 9 , wherein the organic compound layer further includes another light-emitting layer stacked on the light-emitting layer, and the other light-emitting layer emits light of a color different from a color of light emitted from the light-emitting layer.

11. The organic light-emitting element according to claim 10 , wherein the organic light-emitting element emits white light.

12. A display device comprising a plurality of pixels,
wherein the plurality of pixels each include the organic light-emitting element according to claim 7 and a transistor connected to the organic light-emitting element.

13. The display device according to claim 12 , comprising a color filter on a light-emitting side of each of the pixels.

14. An imaging device comprising:
an optical unit having a plurality of lenses;
an imaging element that receives light that has passed through the optical unit; and
a display unit that displays an image,
wherein the display unit displays an image captured by the imaging element, and
the display unit includes the organic light-emitting element according to claim 7 .

15. An electronic device comprising:
a housing;
a communication unit that communicates with an outside; and
a display unit,
wherein the display unit includes the organic light-emitting element according to claim 7 .

16. An illumination device comprising:
a light source; and
a light diffusion unit or an optical film,
wherein the light source includes the organic light-emitting element according to claim 7 .

17. A moving object comprising:
a body; and
a lighting fixture disposed on the body,
wherein the lighting fixture includes the organic light-emitting element according to claim 7 .
