8 Claims

1. A composition for an organic optoelectronic device, the composition comprising:

a first host compound, the first host compound being a compound of Group 3; and

a second host compound represented by Chemical Formula 2,

wherein, in Chemical Formula 2,

Y¹and Y²are each 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,

Z¹and Z²are independently a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof,

R⁴to R⁹are 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

m is an integer of 0 to 2; and

wherein “substituted” of Chemical Formula 2 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.
