Abstract

The present invention relates to a compound for an organic optoelectric device, an organic optoelectric device, to which the compound is applied, and a display device, wherein the compound is represented by chemical formula 1. The detailed contents regarding chemical formula 1 are the same as defined in the specification.

First claim

The invention claimed is:

1. A compound for an organic optoelectric device represented by Chemical Formula I:

wherein, in Chemical Formula I,
Ar 1 to Ar 4 are independently a substituted or unsubstituted C6 to C30 aryl group,
R is independently hydrogen, deuterium, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C1 to C30 alkoxy group, a substituted or unsubstituted C3 to C40 silyl group, or a combination thereof,
each of R is the same or different,
n is an integer of 2 to 10, and
wherein “substituted” refers to replacement of at least one hydrogen by deuterium, a cyano group, a nitro group, a halogen-substituted C1 to C10 alkyl group, a C1 to C40 silyl group, a C1 to C30 alkyl group, a C1 to C10 alkylsilyl group, a C6 to C30 arylsilyl group, a C3 to C30 cycloalkyl group, a C2 to C30 heterocycloalkyl group, a C6 to C30 aryl group, or a C1 to C20 alkoxy group.

2. The compound for an organic optoelectric device of claim 1 , wherein n is an integer of 2 to 5.

3. The compound for an organic optoelectric device of claim 1 , wherein Chemical Formula 1 is represented by one of Chemical Formulae I-1 to I-13:

wherein, in Chemical Formulae I-1 to I-10,
Ar 1 to Ar 4 are independently a substituted or unsubstituted C6 to C30 aryl group, and
R′ is deuterium, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,
wherein “substituted” is the same as defined in claim 1 .

4. The compound for an organic optoelectric device of claim 1 , wherein Ar 1 to Ar 4 are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, or a substituted or unsubstituted quaterphenyl group.

5. The compound for an organic optoelectric device of claim 1 , wherein Ar 1 to Ar 4 are independently selected from substituted or unsubstituted groups of Group I:
[Group I]

wherein, in Group I,
* indicates a binding site with an adjacent atom.

6. The compound for an organic optoelectric device of claim 1 , which is one of compounds of Group II:

7. An organic optoelectric device, comprising
an anode and a cathode facing each other, and
at least one organic layer disposed between the anode and the cathode,
wherein the organic layer includes the compound for an organic optoelectric device of claim 1 .

8. The organic optoelectric device of claim 7 , wherein the organic layer includes a light emitting layer, and
the light emitting layer includes the compound for an organic optoelectric device.

9. The organic optoelectric device of claim 8 , wherein the compound for an organic optoelectric device is included as a host of the light emitting layer.

10. The organic optoelectric device of claim 7 , wherein the organic layer further includes at least one auxiliary layer selected from a hole blocking layer and an electron transport layer, and
the auxiliary layer includes the compound for an organic optoelectric device.

11. The organic optoelectric device of claim 10 , wherein the auxiliary layer further includes an electron transport auxiliary layer that is adjacent to the light emitting layer, and
the electron transport auxiliary layer includes the compound for an organic optoelectric device.

12. A display device comprising the organic optoelectric device of claim 7 .
