Compound for organic optoelectronic device, composition for organic optoelectronic device and organic optoelectronic device and display device

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,
• R1 to R7 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,
• Y1 and Y2 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,
• A1 and A2 are independently substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof,
• R8 to R13 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.
