Abstract

Disclosed are a compound for an organic optoelectronic device represented by Chemical Formula 1, a composition for an organic optoelectronic device, an organic optoelectronic device including the same, and a display device.
Details of Chemical Formula 1 are the same as defined in the specification.

First claim

What is claimed is:

1. A compound for an organic optoelectronic device, wherein the compound is selected from compounds of Group 1:

2. A composition for an organic optoelectronic device, comprising
the first compound for an organic optoelectronic device of claim 1 ; and
a second compound for an organic optoelectronic device represented by Chemical Formula 2:

wherein, in Chemical Formula 2,
Y 1 and Y 2 are independently a single bond, a substituted or unsubstituted C6 to C30 arylene group, a substituted or unsubstituted C2 to C30 heteroarylene group, or a combination thereof,
Ar 3 and Ar 4 are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof,
R 6 to R 11 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C50 heterocyclic group, or a combination thereof, and
n3 is an integer of 0 to 2;
wherein the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C4 alkyl group, a C6 to C18 aryl group, or a C2 to C18 heteroaryl group.

3. The composition for an organic optoelectronic device of claim 2 , wherein Ar 3 and Ar 4 of Chemical Formula 2 are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted pyridinyl group, a substituted or unsubstituted pyrimidinyl group, a substituted or unsubstituted quinazolyl group, a substituted or unsubstituted isoquinazolyl group, a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted carbazolyl group, a substituted or unsubstituted fluorenyl group, or a combination thereof.

4. The composition for an organic optoelectronic device of claim 2 , wherein Chemical Formula 2 has one of structures of Group III,
*—Y 1 —Ar 3 and *—Y 2 —Ar 4 are one of substituents of Group IV:

wherein, in Group III and Group IV, * is a linking point.

5. An organic optoelectronic 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 optoelectronic device of claim 1 ; or
the composition for an organic optoelectronic device of claim 2 .

6. The organic optoelectronic device of claim 5 , wherein the organic layer includes a light-emitting layer, and
the light-emitting layer includes the compound for an organic optoelectronic device or the composition for an organic optoelectronic device.

7. The organic optoelectronic device of claim 6 , wherein the compound for an organic optoelectronic device or the composition for an organic optoelectronic device is included as a host of the light-emitting layer.

8. The organic optoelectronic device of claim 6 , wherein the organic 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 optoelectronic device; or the composition for an organic optoelectronic device.

9. A display device comprising the organic optoelectronic device of claim 5 .
