Abstract

An organic compound represented by formula (1) and an organic compound represented by formula (2). These organic compounds provide high color purity.

In formulae (1) and (2), R 1 to R 24 are each independently selected from the group consisting of a hydrogen atom and a substituent.

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 in formula (1), at least one of R 1 to R 24 is the aryl group.

3 . The organic compound according to claim 2 , wherein the aryl group is a phenyl group, and the phenyl group has a substituent at an ortho position.

4 . The organic compound according to claim 3 , wherein the substituent at the ortho position of the phenyl group is selected from 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.

5 . The organic compound according to claim 4 , wherein the substituent at the ortho position of the phenyl group is selected from a phenyl group and an alkyl group having 1 to 10 carbon atoms.

6 . The organic compound according to claim 1 , wherein in formula (1), at least two of R 8 , R 13 , and R 20 are each the aryl group.

7 . The organic compound according to claim 6 , wherein in formula (1), R 8 , R 13 , and R 20 are each the aryl group.

8 . An organic compound represented by formula (2):

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.

9 . The organic compound according to claim 8 , wherein R 1 to R 24 are each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 18 carbon atoms.

10 . The organic compound according to claim 9 , wherein the aryl group has a substituent at an ortho position.

11 . An organic light-emitting element comprising:
a first electrode; a second electrode; and an organic compound layer disposed between the first electrode and the second electrode, wherein the organic compound layer contains the organic compound according to claim 1 .

12 . The organic light-emitting element according to claim 11 , wherein the organic compound layer includes a light-emitting layer.

13 . The organic light-emitting element according to claim 12 , 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 having a color different from a color of light emitted from the light-emitting layer.

14 . The organic light-emitting element according to claim 13 , wherein the organic light-emitting element emits white light.

15 . An organic light-emitting element comprising:
a first electrode; a second electrode; and an organic compound layer disposed between the first electrode and the second electrode, wherein the organic compound layer contains the organic compound according to claim 8 .

16 . A display apparatus comprising a plurality of pixels,
wherein the plurality of pixels each include the organic light-emitting element according to claim 11 and a transistor connected to the organic light-emitting element.

17 . An image pickup apparatus comprising:
an optical unit including a plurality of lenses; an image pickup 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 image pickup element, and the display unit includes the organic light-emitting element according to claim 11 .

18 . An electronic device comprising:
a display unit including the organic light-emitting element according to claim 11 ; a housing provided with the display unit; and a communication unit that is provided in the housing and communicates with an outside.

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

20 . A moving object comprising:
a lighting fixture including the organic light-emitting element according to claim 11 ; and a body provided with the lighting fixture.
