Abstract

An organic compound represented by formula [1] is provided.Ring A is a polycyclic aromatic hydrocarbon ring having a fluoranthene skeleton and having 16 to 60 carbon atoms and optionally has, as a substituent, a substituted or unsubstituted alkyl group or the like. Rings B1 and B2 are aromatic hydrocarbon rings having 6 to 18 carbon atoms and each have two or more electron withdrawing groups. Q1 and Q2 respectively represent one of the electron withdrawing groups of the ring B1 and one of the electron withdrawing groups of the ring B2, and are respectively located at an ortho position of the ring B1 and at an ortho position of the ring B2 with respect to the ring A.

First claim

What is claimed is:

1. An organic compound represented by formula [1],

wherein ring A is any one of FF7, FF8, FF9, FF10, FF12, FF13, or FF14 and optionally has, as a substituent, 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, or a silyl group,
rings B 1 and B 2 are aromatic hydrocarbon rings having 6 to 18 carbon atoms,
the ring B 1 has two or more electron withdrawing groups, and Q 1 represents one of the electron withdrawing groups of the ring B 1 , is a cyano group and is located at an ortho position of the ring B 1 with respect to the ring A, and
the ring B 2 has two or more electron withdrawing groups, and Q 2 represents one of the electron withdrawing groups of the ring B 2 , is a cyano group and is located at an ortho position of the ring B 2 with respect to the ring A

2. The organic compound according to claim 1 , wherein the ring A is FF12 or FF14.

3. The organic compound according to claim 1 ,
wherein the ring A has a fluoranthene skeleton represented by formula [2] or a benzo(k)fluoranthene skeleton represented by formula [3], and
the rings B 1 and B 2 bond to the ring A at any one of positions * in the formula [2] or [3]

4. The organic compound according to claim 1 , wherein the ring B 1 and the ring B 2 have the same structure, and Q 1 and Q 2 represent the same electron withdrawing group.

5. The organic compound according to claim 1 , wherein the rings B 1 and B 2 are any one of a benzene ring and a naphthalene ring.

6. The organic compound according to claim 1 , wherein one or more of the two or more withdrawing groups that the ring B 1 has, other than Q 1 , is selected from a group consisting of a fluorine atom, a trifluoromethyl group, and a cyano group, and one or more of the two or more withdrawing groups that the ring B 2 has, other than Q 2 , is selected from a group consisting of a fluorine atom, a trifluoromethyl group, and a cyano group.

7. The organic compound according to claim 1 , wherein the two or more withdrawing groups that the ring B 1 has are cyano groups, and the two or more withdrawing groups that the ring B 2 has are cyano groups.

8. The organic compound according to claim 1 , wherein when a substituent is further introduced to the alkyl group, the alkoxy group, the amino group, the aryl group, the heterocyclic group, and the aryloxy group, the substituent represents alkyl group, aralkyl group, aryl group, heterocyclic group, amino group, alkoxy group, aryloxy group, halogen atom, or cyano group.

9. An organic light-emitting element comprising:
an anode;
a cathode; and
an organic compound layer disposed between the anode and the cathode,
wherein the organic compound layer comprises one or more layers, and
at least one layer of the one or more layers includes the organic compound according to claim 1 .

10. The organic light-emitting element according to claim 9 , wherein the layer including the organic compound is a light-emitting layer.

11. The organic light-emitting element according to claim 10 ,
wherein the organic compound layer further includes another light-emitting layer disposed together with the light-emitting layer so as to form a multilayer structure, and
the other light-emitting layer emits light having a color different from a color of light emitted from the light-emitting layer.

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

13. A display apparatus comprising a plurality of pixels,
wherein at least one of the plurality of pixels includes the organic light-emitting element according to claim 9 and a transistor connected to the organic light-emitting element.

14. A photoelectric conversion apparatus comprising:
an optical unit including a plurality of lenses;
an image pickup element that receives light which has passed through the optical unit; and
a display unit that displays an image captured by the image pickup element, wherein the display unit includes the organic light-emitting element according to claim 9 .

15. An electronic apparatus comprising:
a display unit including the organic light-emitting element according to claim 9 ;
a housing in which the display unit is disposed; and
a communication unit that is disposed in the housing and communicates with an external unit.

16. A lighting apparatus comprising:
