Abstract

A compound represented by Formula 1. An organic electric element includes a first electrode, a second electrode, and an organic material layer between the first electrode and the second electrode. The organic material layer includes the compound. When the organic electric element includes the compound in an organic material layer, luminous efficiency, stability, and life span can be improved.

First claim

The invention claimed is:

1. A compound of Formula 9,

wherein Y is S,
R 1 to R 4 and R 11 to R 14 are hydrogen;
L is a single bond or a C 6 -C 60 arylene group;
Ar′ is a substituted or unsubstituted C 6 -C 60 aryl group, or a substituted or unsubstituted fluorenyl group, wherein the aryl group is optionally substituted by a deuterium or C 6 -C 20 aryl group, and the fluorenyl group is optionally substituted by a C 1 -C 20 alkyl group; and
X 1 to X 4 are each independently CR 41 or N, wherein R 41 is hydrogen.

2. The compound of claim 1 , wherein Ar′ is an unsubstituted C 6 -C 20 aryl group or a C 6 -C 20 aryl group substituted with a deuterium.

3. The compound of claim 1 , wherein X 1 to X 4 are CH.

4. The compound of claim 1 , wherein Ar′ is an unsubstituted C 6 -C 20 aryl group and X 1 to X 4 are CH.

5. The compound of claim 4 , wherein Ar′ is phenyl.

6. The compound of claim 1 represented by one of the following compounds:

7. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises the compound of claim 1 .

8. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises the compound of claim 3 .

9. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises the compound of claim 5 .

10. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer is formed with the compound of claim 1 by a soluble process.

11. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises a light emitting layer comprising the compound of claim 1 .

12. An organic electric element comprising a first electrode, a second electrode and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises a light emitting layer comprising the compound of claim 1 as phosphorescent red host material.

13. An electronic device comprising a display device, the display device comprising the organic electric element of claim 4 and a control unit for driving the display device.

14. The electronic device of claim 13 , wherein the organic electric element comprises at least one of an organic light emitting diode (OLED), an organic solar cell, an organic photo conductor (OPC), an organic transistor (organic TFT), and an element for monochromatic or white illumination.
