Abstract

A composition for an organic optoelectronic device, an organic optoelectronic device including the same, and a display device, the composition including a first compound represented by Chemical Formula 1 and a second compound represented by a combination of Chemical Formula 2 and Chemical Formula 3,

First claim

What is claimed is:

1 . A composition for an organic optoelectronic device, the composition comprising:
a first compound represented by Chemical Formula 1, and a second compound represented by a combination of Chemical Formula 2 and Chemical Formula 3,

wherein, in Chemical Formula 1,
R 1 to R 12 are each independently hydrogen, deuterium, a cyano group, a halogen, a substituted or unsubstituted C1 to C30 alkyl group, or a substituted or unsubstituted C6 to C30 aryl group,
L 1 is a single bond or a substituted or unsubstituted C6 to C30 arylene group, and
ET is 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 quinazolinyl group, a substituted or unsubstituted quinoxalinyl group, a substituted or unsubstituted naphthyridinyl group, a substituted or unsubstituted benzofuranpyrimidinyl group, or a substituted or unsubstituted benzothiophenepyrimidinyl group;

wherein, in Chemical Formula 2 and Chemical Formula 3,
Ar is a substituted or unsubstituted C6 to C30 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group,
two adjacent ones of a1* to a4* of Chemical Formula 2 are linking carbons linked at * of Chemical Formula 3, the remaining two of a1* to a4* of Chemical Formula 2, not linked at * of Chemical Formula 3, are CR a ,
R a and R 13 to R 20 are each independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted amine group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, or a substituted or unsubstituted C2 to C30 heterocyclic group, and
at least one of R 17 to R 20 is a group represented by Chemical Formula a,

wherein, in Chemical Formula a,
L a , L b , and L c are each independently a single bond, a substituted or unsubstituted C6 to C20 arylene group, or a substituted or unsubstituted C2 to C20 heterocyclic group,
R b and R c are each independently a substituted or unsubstituted C6 to C30 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group, and
* is a linking point.

2 . The composition 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 quinoxalinyl group, a substituted or unsubstituted benzofuranpyrimidinyl group, or a substituted or unsubstituted benzothiophenepyrimidinyl group.

3 . The composition as claimed in claim 1 , wherein ET of Chemical Formula 1 is a group of Group I:

4 . The composition as claimed in claim 1 , wherein the first compound is a compound of Group 1:

5 . The composition as claimed in claim 1 , wherein:
the second compound is represented by Chemical Formula 2A, Chemical Formula 2B, or Chemical Formula 2C,

in Chemical Formula 2A to Chemical Formula 2C,
Ar and R 13 to R 20 are defined the same as those of Chemical Formulae 2 and 3, and
R a1 to R a4 are each independently defined the same as R a of Chemical Formula 2.

6 . The composition as claimed in claim 1 , wherein Chemical Formula a is a group of Group II:

7 . The composition as claimed in claim 1 , wherein:
the second compound is represented by Chemical Formula 2A-1, Chemical Formula 2A-2, Chemical Formula 2A-3, or Chemical Formula 2A-4,

in Chemical Formula 2A-1 to Chemical Formula 2A-4,
Ar is 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 phenanthrenyl group, a substituted or unsubstituted triphenylenyl group, a substituted or unsubstituted fluorenyl group, a substituted or unsubstituted dibenzofuranyl group, a substituted or unsubstituted dibenzothiphenyl group, or a substituted or unsubstituted carbazolyl group,
R a3 , R a4 and R 13 to R 20 are each independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted C1 to C10 alkyl group, or a substituted or unsubstituted C6 to C12 aryl group,
L a is a single bond, a substituted or unsubstituted phenylene group, a substituted or unsubstituted biphen
