Abstract

The present invention relates to a novel stable benzo[h]hexaphene compound and an organic light-emitting device including the compound. The present invention provides a benzo[h]hexaphene shown in claim 1.

First claim

The invention claimed is:

1. A benzo[h]hexaphene represented by the following Formula (1):

wherein,
R 1 to R 16 are each independently selected from a hydrogen atom, a halogen atom, a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, a cyano group, a diphenylamino group, a pyridyl group, a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group;
the diphenylamino, pyridyl, phenyl, biphenyl, terphenyl, and naphthyl groups optionally have a substitutent of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, or a fluorine atom;
Ar 1 and Ar 2 are any of a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group; and
Ar 1 and Ar 2 optionally have a substitutent of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, or a fluorine atom.

2. The benzo[h]hexaphene according to claim 1 , represented by the following Formula (2):

wherein,
R 17 to R 24 are each independently selected from a hydrogen atom, a halogen atom, a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, a cyano group, a diphenylamino group, a pyridyl group, a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group;
the diphenylamino, pyridyl, phenyl, biphenyl, terphenyl, and naphthyl groups optionally have a substituent of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, or a fluorine atom;
Ar 3 and Ar 4 are any of a phenyl group, a biphenyl group, a terphenyl group, and a naphthyl group; and
Ar 3 and Ar 4 optionally have a substituent of a methyl group, an ethyl group, an iso-propyl group, a t-butyl group, or a fluorine atom.

3. An organic light-emitting device comprising a cathode, an anode, and an organic compound layer disposed between the anode and the cathode, wherein
the organic compound layer includes at least one layer including 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 benzo[h]hexaphene.

6. An 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 benzo[h]hexaphene; 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 an active device 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 active device is disposed in the substrate.

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 is a display apparatus according to claim 8 .

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

11. An image-forming apparatus comprising:
a photosensitive member;
a charging unit for charging a surface of the photosensitive member;
an exposure unit for forming an electrostatic latent image by exposing the photosensitive member; and
a developing unit for developing the electrostatic latent image formed on the surface of the photosensitive member, wherein
the exposure unit includes an organic light-emitting device according to claim 3 .

12. An exposure light source of an electrophotographic image forming apparatus comprising the organic light-emitting device according to claim 3 .
