Abstract

A compound for an organic optoelectric device represented by Chemical Formula I, an organic optoelectric device including the same, and a display device are disclosed. Details of Chemical Formula I are defined in the specification.

First claim

What is claimed is:

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

wherein, in Chemical Formula I,
a 1 * to a 4 * are independently C or CR c ,
a 1 * or a 2 * is linked with b 1 *,
a 3 * or a 4 * is linked with b 2 *,
R 1 to R 12 and R c are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C20 aryl group, a substituted or unsubstituted C2 to C30 heteroaryl group, or a combination thereof,
R 5 to R 12 are independently present or R 5 and R 6 , R 6 and R 7 , R 7 and R 8 , R 9 and R 10 , R 10 and R 11 , and R 11 and R 12 are optionally fused to form a ring,
L 1 and L 2 are independently a single bond, a substituted or unsubstituted C6 to C30 arylene group, or a substituted or unsubstituted C2 to C30 heteroarylene group,
R a and R b are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heteroaryl group, or a combination thereof,
n1 and n2 are independently an integer of 0 or 1, and
1≤n1+n2≤2,
wherein the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C30 alkyl group, a C6 to C30 aryl group, or a C2 to C30 heteroaryl group.

2. The compound for an organic optoelectric device of claim 1 , which is represented by one of Chemical Formulae I-A to I-E:

wherein, in Chemical Formulae I-A to I-E,
R 1 , R 2 , and R 4 to R 12 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C10 alkyl group, a substituted or unsubstituted C6 to C20 aryl group, a substituted or unsubstituted C2 to C30 heteroaryl group, or a combination thereof,
L 1 and L 2 are independently a single bond, a substituted or unsubstituted C6 to C30 arylene group, or a substituted or unsubstituted C2 to C30 heteroarylene group,
R a and R b are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heteroaryl group, or a combination thereof, and
the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C30 alkyl group, a C6 to C30 aryl group, or a C2 to C30 heteroaryl group.

3. The compound for an organic optoelectric device of claim 1 , wherein L 1 and L 2 are independently a single bond, a phenylene group, a biphenylene group, a terphenylene group, a quaterphenylene group, or a combination thereof.

4. The compound for an organic optoelectric device of claim 3 , wherein L 1 and L 2 are independently a single bond or selected from linking groups of Group 1:

wherein, in Group 1,
* is a linking site with an adjacent atom.

5. The compound for an organic optoelectric device of claim 1 , wherein R a and R b are independently a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, a substituted or unsubstituted quaterphenyl group, a substituted or unsubstituted pyridinyl group, a substituted or unsubstituted pyrimidinyl group, a substituted or unsubstituted triazinyl group, a substituted or unsubstituted quinolinyl group, a substituted or unsubstituted isoquinolinyl group, a substituted or unsubstituted indolyl group, a substituted or unsubstituted azaindolyl group, a substituted or unsubstituted benzoxazolyl group, a substituted or unsubstituted benzthiazolyl group, a substituted or unsubstituted azatriphenylenyl group, a substituted or unsubstituted azaphenanthrenyl group, a substituted or unsubstituted quinazolinyl group, or a combination thereof, and
the “substituted” refers to replacement of at least one hydrogen by deuterium, C1 to C30 alkyl group, C6 to C30 aryl group, or C2 to C30 heteroaryl group.

6. The compound for an organic optoelectric device of claim 5 , wherein R a and R b are independently selected from substituents of Group 2:

wherein, in Group 2,
* is a linking site with an adjacent atom.

7. The compound for an organic optoelectric device of claim 1 , which is selected from compounds of Group 3:
