A compound for an organic optoelectronic device represented by Chemical Formula 1 is provided to fabricate an organic photoelectric device having excellent electrochemical and thermal stability and life-span characteristics, and high luminous efficiency at a low driving voltage.

First claim

What is claimed is:

1. A compound for an organic optoelectronic device, the compound being asymmetrical and represented by the following Chemical Formula 2:

wherein, in Chemical Formula 2,
X 1 and X 2 are each independently selected from the group of —NR′—, —O—, and —S—, wherein R′ is selected from the group of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, and a substituted or unsubstituted C2 to C30 heteroaryl group, the C2 to C30 heteroaryl group having electronic properties,
R 1 to R 6 are each independently selected from the group of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, and a substituted or unsubstituted C2 to C30 heteroaryl group, the C2 to C30 heteroaryl group having electronic properties,
at least one of R 1 to R 6 or R′ is a substituted or unsubstituted C2 to C30 heteroaryl group, the C2 to C30 heteroaryl group having electronic properties, and
at least one of X 1 and X 2 is —NR′— wherein R′ includes a substituted or unsubstituted pyridinyl group, a substituted or unsubstituted pyrimidinyl group, or a substituted or unsubstituted triazinyl group.

2. The compound as claimed in claim 1 , wherein the compound is represented by the following Chemical Formula B-1:

wherein, in Chemical Formulae B-1,
X 1 is selected from the group of —O— and —S—,
R 1 to R 6 are each independently selected from the group of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, and a substituted or unsubstituted C2 to C30 heteroaryl group,
Ar is represented by one of the following Chemical Formulae E-1 to E-5,
L is selected from the group of a single bond, a substituted or unsubstituted C2 to C10 alkenylene group, a substituted or unsubstituted C2 to C10 alkynylene group, a substituted or unsubstituted C6 to C30 arylene group, and a substituted or unsubstituted C2 to C30 heteroarylene group, and
n is an integer ranging from 1 to 2,

3. An organic light emitting diode, comprising:
an anode; a cathode; and at least one organic thin layer between the anode and the cathode, the at least one organic thin layer including the compound as claimed in claim 1 .

4. The organic light emitting diode as claimed in claim 3 , wherein the compound is included in an emission layer.

5. The organic light emitting diode as claimed in claim 4 , wherein the compound is used as a phosphorescent or fluorescent host material in the emission layer.

6. The organic light emitting diode as claimed in claim 4 , wherein the compound is used as a fluorescent blue dopant material in the emission layer.

7. A display device comprising the organic light emitting diode as claimed in claim 3 .

8. A compound for an organic optoelectronic device, the compound being asymmetrical and represented by the following Chemical Formula S-2:

wherein, in Chemical Formula S-2,
R 1 to R 6 are each independently selected from the group of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, and a substituted or unsubstituted C2 to C30 heteroaryl group,
L 1 and L 2 are each independently selected from the group of a single bond, a substituted or unsubstituted C2 to C10 alkenylene group, a substituted or unsubstituted C2 to C10 alkynylene group, a substituted or unsubstituted C6 to C30 arylene group, and substituted or unsubstituted C2 to C30 heteroarylene group,
n1 and n2 are each independently an integer ranging from 1 to 2,
Ar 1 and Ar 2 are each independently selected from the group of a substituted or unsubstituted C6 to C30 aryl group and a substituted or unsubstituted C2 to C30 heteroaryl group, the C2 to C30 heteroaryl group having electronic properties, and
one of Ar 1 and Ar 2 is a substituted or unsubstituted pyridinyl group, a substituted or unsubstituted pyrimidinyl group, or a substituted or unsubstituted triazinyl group.

9. The compound as claimed in claim 8 , wherein one of Ar 1 and Ar 2 is represented by one of the following Chemical Formulae E-1 to E-5:

10. An organic light emitting diode, comprising:
an anode; a cathode; and at least one organic thin layer between the anode and the cathode, the at least one organic thin layer including the compound as claimed in claim 8 .
