Compound for organic optoelectronic diode, organic optoelectronic diode comprising same, and display device

A compound for an organic optoelectronic diode, the compound represented by a combination of Chemical Formula 1 and Chemical Formula 2:

• wherein, in Chemical Formulas 1 and 2,
• X1 is N, or C-L1-R1,
• X2 is N, or C-L2-R2,
• Y is O, S, CRaRb, or SiRcRd,
• L1 to L3 are independently a single bond, C6 to C30 arylene group, a substituted or unsubstituted C2 to C30 heteroarylene group, or a combination thereof,
• R1 to R3 and Ra to Rd are independently hydrogen, deuterium, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C3 to C30 cycloalkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, a substituted or unsubstituted C6 to C30 arylamine group, a substituted or unsubstituted C1 to C30 alkoxy group, a substituted or unsubstituted C3 to C40 silyl group, a halogen, a halogen-containing group, a cyano group, a hydroxyl group, an amino group, a nitro group, a carboxyl group, a ferrocenyl group, or a combination thereof, and
• adjacent two *'s of Chemical Formula 1 are linked with *'s of Chemical Formula 2 to form a fused ring,
• wherein “substituted” refers to replacement of at least one hydrogen by deuterium, a halogen, a hydroxy group, an amino group, C1 to C30 amine group, a nitro group, a C1 to C40 silyl group, a C1 to C30 alkyl group, a C3 to C30 cycloalkyl group, a C2 to C30 heterocycloalkyl group, a C6 to C30 aryl group, a C2 to C30 heteroaryl group, a C1 to C20 alkoxy group, a fluoro group, a C1 to C10 trifluoroalkyl group, or a cyano group.
