Target is to provide an organic compound material having a bipolar
character.A quinoxaline derivative represented by a general formula (1)
is provided. In the formula, R.sup.1-R.sup.12 each independently
represents a hydrogen atom, a halogen atom, a lower alkyl group, an
alkoxy group, an acyl group, a nitro group, a cyano group, an amino
group, a dialkylamino group, a diarylamino group, a vinyl group, an aryl
group, or a heterocyclic residue group. R.sup.9 and R.sup.10, R.sup.10
and R.sup.11, and R.sup.11 and R.sup.12 are each independent or
respectively mutually bonded to form an aromatic ring. Ar.sup.1-Ar.sup.4
each independently represents an aryl group or a heterocyclic residue
group. Ar.sup.1, Ar.sup.2, Ar.sup.3 and Ar.sup.4 are each independent or
Ar.sup.1 and Ar.sup.2, and Ar.sup.3 and Ar.sup.4 are respectively
mutually bonded directly, or Ar.sup.1 and Ar.sup.3, and Ar.sup.3 and
Ar.sup.4 are bonded via oxygen (O), sulfur (S) or a carbonyl group.
