1. An organic compound represented by formula [1-1] or [1-2]:

OG Complex Work Unit Chemistry
where in formula [1-1] or [1-2], R1 to R20 are each independently selected from a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted amino group, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted aryloxy group, a silyl group, and a cyano group,
wherein at least one of R1 to R4 and R6 to R9 and at least one of R11 to R14 and R16 to R19 are substituted or unsubstituted amino groups, and groups bonded to nitrogen atoms of the substituted or unsubstituted amino groups are optionally taken together to form a ring structure,
X1 to X4 are each oxygen, sulfur, selenium, or tellurium and are optionally the same or different,
when, in formula [1-1], X1 and X2 are sulfur, and at least one of both R3 and R7 and both R2 and R8 are substituted amino groups, a substituent of the respective substituted amino groups forms a ring by bonding, and
and when, in formula [1-2], X3 and X4 are sulfur, and at least one of both R13 and R17 and both R12 and R18 are substituted amino groups, the amino groups do not include an N-H bond.
