Abstract

The present invention provides a novel stable benzo[a]naphtho[2,1-c]tetracene compound and an organic light-emitting device including the compound. Provided is an organic compound represented by Formula [1].

In Formula [1], R 1 to R 16 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, a cyano group, a diphenylamino group, a pyridyl group, and an aryl group.

First claim

The invention claimed is:

1. An organic compound represented by the following Formula [1];

wherein,
R 1 to R 16 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, a cyano group, a diphenylamino group, a pyridyl group, and an aryl group, wherein
the diphenylamino group, the pyridyl group, and the aryl group each optionally have at least one substituent selected from the group consisting of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, and a fluorine atom; and
Ar 1 and Ar 2 are each any of a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group, wherein
Ar 1 and Ar 2 each optionally have at least one substituent selected from the group consisting of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, and a fluorine atom.

2. The organic compound according to claim 1 , represented by the following Formula [2]:

wherein,
R 17 to R 24 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms, a cyano group, a diphenylamino group, a pyridyl group, and an aryl group, wherein
the diphenylamino group, the pyridyl group, and the aryl group each optionally have at least one substituent selected from the group consisting of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, and a fluorine atom; and
Ar 3 and Ar 4 are each any of a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group, wherein
Ar 3 and Ar 4 each optionally have at least one substituent selected from the group consisting of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, and a fluorine atom.

3. An organic light-emitting device comprising a pair of electrodes and an organic compound layer disposed between the pair of electrode, wherein
the organic compound layer includes an organic compound according to claim 1 .

4. The organic light-emitting device according to claim 3 , wherein the organic compound layer is a light-emitting layer.

5. The organic light-emitting device according to claim 4 , wherein the light-emitting layer includes a host material and a guest material, and the host material is the organic compound represented by Formula [1].

6. The organic light-emitting device according to claim 3 , wherein
the organic compound layer includes a light-emitting portion including a plurality of organic compounds;
at least one of the plurality of organic compounds is the organic compound represented by Formula [1]; and
the light-emitting portion emits white light.

7. A display apparatus comprising:
a plurality of pixels each including an organic light-emitting device according to claim 3 and a transistor connected to the organic light-emitting device.

8. The display apparatus according to claim 7 , wherein
the organic light-emitting device is disposed on a substrate; and
the substrate has the transistor therein.

9. An image display apparatus comprising:
an input section for inputting image information and a display section for displaying an image, wherein
the display section includes a plurality of pixels each including an organic light-emitting device according to claim 3 and a transistor connected to the organic light-emitting device.

10. A lighting system comprising:
an organic light-emitting device according to claim 3 ; and
a converter circuit connected to the organic light-emitting device.
