Abstract

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

First claim

What is claimed is:

1 . An organic optoelectronic device, comprising:
an anode and a cathode facing each other, and at least one organic layer between the anode and the cathode, wherein: the at least one organic layer includes a composition including a first compound and a second compound, the first compound is represented by a combination of Chemical Formula 1 and Chemical Formula 2-1-i or Chemical Formula 2-1-ii,

in Chemical Formulae 1, 2-1-i, and 2-1-ii,
Ar is a substituted or unsubstituted C12 to C30 aryl group,
a1* and a2* are linking carbons, linked at * of Chemical Formula 2-1-i or at * of Chemical Formula 2-1-ii,
a3* and a4* are each independently C—R a ,
R a and R 1 to R 13 are each independently hydrogen, deuterium, a cyano group, a halogen, a substituted or unsubstituted C1 to C20 alkyl group, or a substituted or unsubstituted C6 to C20 aryl group,
R 14 is a substituted or unsubstituted C6 to C20 aryl group, and
the second compound is represented by Chemical Formula 3,

in Chemical Formula 3,
Y 1 and Y 2 are each independently a substituted or unsubstituted C6 to C20 aryl group or a substituted or unsubstituted C2 to C30 heterocyclic group,
L 1 and L 2 are each independently a single bond or a substituted or unsubstituted C6 to C20 arylene group,
R b and R 15 to R 24 are each independently hydrogen, deuterium, a cyano group, a halogen, a substituted or unsubstituted amino 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
m is an integer of 0 to 2,
and a ratio of the first compound to the second compound is 3:7 to 6:4.

2 . The organic optoelectronic device as claimed in claim 1 , wherein Ar is 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, or a substituted or unsubstituted triphenylene group.

3 . The organic optoelectronic device as claimed in claim 1 , wherein:
Ar is a group of Group I:

in Group I, * is a linking point.

4 . The organic optoelectronic device as claimed in claim 1 , wherein R 14 is a substituted or unsubstituted phenyl group, a substituted or unsubstituted biphenyl group, a substituted or unsubstituted terphenyl group, or a substituted or unsubstituted naphthyl group.

5 . The organic optoelectronic device as claimed in claim 1 , wherein R 9 to R 13 are each independently hydrogen, deuterium, a substituted or unsubstituted phenyl group, or a substituted or unsubstituted biphenyl group.

6 . The organic optoelectronic device as claimed in claim 1 , wherein the compound is a compound of Group 1:

7 . The organic optoelectronic device as claimed in claim 1 , wherein:
Chemical Formula 3 is represented by Chemical Formula 3-8;

in Chemical Formula 3-8,
