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

wherein, in Chemical Formula 1,
R 1 to R 7 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C6 to C18 aryl group,
L is a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C30 heteroarylene group, and
ET is a substituted or unsubstituted C2 to C30 heterocyclic group including at least two N's,
wherein, in Chemical Formula 1, the “substituted” refers to replacement of at least one hydrogen by deuterium, a cyano group, a C1 to C20 alkyl group, a C6 to C30 aryl group, or a C2 to C30 heteroaryl group;

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,
A 1 and A 2 are independently substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof,
R 8 to R 13 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 C30 heterocyclic group, or a combination thereof, and
l 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 C30 heteroaryl group.

2. The composition for an organic optoelectronic device as claimed in claim 1 , wherein ET of Chemical Formula 1 is a substituted or unsubstituted pyrimidinyl group, a substituted or unsubstituted triazinyl group, a substituted or unsubstituted quinazolinyl group, a substituted or unsubstituted benzoquinazolinyl group, a substituted or unsubstituted benzothieno[3,2-d]pyrimidinyl group, a substituted or unsubstituted benzothieno[2,3-d]pyrimidinyl group, a substituted or unsubstituted benzofuro[3,2-d]pyrimidinyl group, or a substituted or unsubstituted benzofuro[2,3-d]pyrimidinyl group.

3. The composition for an organic optoelectronic device as claimed in claim 1 , wherein the first compound represented by Chemical Formula 1 is represented by one of Chemical Formula 1-I, Chemical Formula 1-II, Chemical Formula 1-III, Chemical Formula 1-IV, Chemical Formula 1-V and Chemical Formula 1-VI:

wherein, in Chemical Formula 1-I, Chemical Formula 1-II, Chemical Formula 1-III, Chemical Formula 1-IV, Chemical Formula 1-V, and Chemical Formula 1-VI,
Z 1 , Z 3 , Z 5 , and Z 6 to Z 5 are independently N or CR a ,
m and n are independently an integer of 0 to 2,
X is O or S,
at least two of Z 1 , Z 3 and Z 5 of Chemical Formula 1-I to Chemical Formula 1-V are N,
at least two of Z 11 to Z 14 of Chemical Formula 1-VI are N,
R a and R 1 to R 7 are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C5 alkyl group, or a substituted or unsubstituted C6 to C18 aryl group, and
L is a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C30 heteroarylene group.

4. The composition for an organic optoelectronic device as claimed in claim 1 , wherein ET of Chemical Formula 1 is selected from substituents of Group I:

wherein, in Group I,
is a linking point with “L” of Chemical Formula 1.

5. The composition for an organic optoelectronic device as claimed in claim 1 , wherein L of Chemical Formula 1 is a single bond, a substituted or unsubstituted phenylene group, a substituted or unsubstituted biphenylene group, a substituted or unsubstituted terphenylene group, or a substituted or unsubstituted naphthylene group.

6. The composition for an organic optoelectronic device as claimed in claim 1 , wherein the first compound represented by Chemical Formula 1 is selected from compounds of Group 1:

7. The composition for an organic optoelectronic device as claimed in claim 1 , wherein A 1 and A 2 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 quaterphenyl group, a substituted or unsubstituted naphthyl group, a substituted or unsubstituted anthracenyl group, a substituted or unsubstituted triphenylene group, a substituted or unsubstituted pyridinyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or un
