1. A compound for an organic photoelectronic element represented by a combination of Chemical Formula 1 and Chemical Formula 2:

OG Complex Work Unit Chemistry
wherein, in Chemical Formula 1 and Chemical Formula 2,
X is O, S, or CRaRb,
adjacent two of a1*, a2*, a3*, and a4* are C and binding portions with *b1 and *b2,
two of a1*, a2*, a3*, and a4* that are not bound to *b1 and *b2 are independently CRc,
R1 to R4, Ra, Rb, and RC are independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted C1 to C30 silyl group, a substituted or unsubstituted C1 to C30 alkyl group, or a substituted or unsubstituted C6 to C30 aryl group,
L1 to L4 are independently a single bond, a substituted or unsubstituted C6 to C30 arylene group or a quinazolinylene group,
R5 to R8 are independently hydrogen, deuterium, a cyano group, a substituted or unsubstituted C1 to C30 silyl group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, an oxygen-containing C2 to C30 heterocyclic group, or a sulfur-containing C2 to C30 heterocyclic group, and
at least one of L1 to L4 is a quinazolinylene group or at least one of R5 to R8 is a substituted or unsubstituted quinazolinyl group,
wherein the “substituted” refers to replacement of at least one hydrogen by deuterium, a C1 to C10 alkyl group, a C6 to C30 aryl group, a C2 to C20 heterocycle, or a cyano group.
