Abstract

A novel organic compound having high stability is provided. The organic compound is represented by Formula (1) described in claim 1:
In Formula (1), R 1 and R 2 each independently selected from a hydrogen atom, Substituent group A, and Substituent group B shown in claim 1 , wherein at least one of R 1 and R 2 is selected from Substituent group A or Substituent group B; and R 11 and R 12 of a substituent belonging to Substituent group A are each independently selected from Substituent group B.

First claim

The invention claimed is:

1. An organic light emitting device comprising:
a pair of electrodes; and
an organic compound layer disposed between the pair of electrodes, wherein
the organic compound layer includes an organic compound represented by the following formula (1):

wherein R 1 and R 2 each independently selected from a hydrogen atom, Substituent group A shown below, and Substituent group B shown below, wherein
at least one of R 1 and R 2 is selected from Substituent group A or Substituent group B;
R 11 and R 12 of a substituent belonging to Substituent group A are each independently selected from Substituent group B; and
each substituent belonging to Substituent group A or Substituent group B optionally has a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a silyl group, or a cyano group at a position other than the R 11 and R 12 substitution positions:

2. The organic light-emitting device according to claim 1 , wherein the substituent belonging to Substituent group B has a tertiary butyl group as a substituent.

3. The organic light-emitting device according to claim 1 , wherein
the organic compound layer includes a first light-emitting layer, the first light-emitting layer comprising the organic compound.

4. The organic light-emitting device according to claim 3 , wherein
the first light-emitting layer includes a host material and a guest material, and the host material comprises the organic compound.

5. The organic light-emitting device according to claim 4 , wherein the first light-emitting layer further includes an assist material.

6. The organic light-emitting device according to claim 5 , wherein
the organic compound layer further includes a second light-emitting layer laminated on the first light-emitting layer, wherein the first and the second light-emitting layers emit light of colors different from each other; and
the device emits white light.

7. The organic light-emitting device according to claim 4 , wherein
the organic compound layer further includes a second light-emitting layer laminated on the first light-emitting layer, wherein the first and the second light-emitting layers emit light of colors different from each other; and
the device emits white light.

8. The organic light-emitting device according to claim 4 , wherein the guest material comprises a phosphorescent material.

9. The organic light-emitting device according to claim 8 , wherein the phosphorescent material is Ir(ppy)3 and Ir(piq)3.

10. The organic light-emitting device according to claim 3 , wherein
the organic compound layer has a light-emitting portion containing a plurality of light-emitting materials;
the plurality of light-emitting materials emit light of colors different from each other; and
the device emits white light.

11. A display apparatus comprising:
a plurality of pixels, wherein
the pixels each at least include an organic light-emitting device according to claim 3 and an active device connected to the organic light-emitting device.

12. An image information processing apparatus comprising:
an image input section for inputting image information, and
a display section for displaying an image, wherein
the display section includes a display apparatus according to claim 11 .

13. The display apparatus according to claim 11 , further comprising:
a substrate, wherein
the active device is integrated on the substrate.

14. A lighting system comprising:
organic light-emitting device according to claim 3 , and
a converter circuit for supplying a drive voltage to the organic light-emitting device.

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

16. An exposure machine for exposing a photosensitive member to light, the machine comprising:
organic light-emitting devices according to claim 3 , wherein
the organic light-emitting devices are arranged in a line.
