An object is to provide an organic compound material having bipolar properties. Provided is a quinoxaline derivative represented by the general formula (1). In the formula, R 1 to R 12 are each independently 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, It represents either an aryl group or a heterocyclic residue. R 9 and R 10, R 1 0 and R 11, R 11 and R 12 are each independently, or combined with each other to form an aromatic ring. Ar 1 to Ar 4 each independently represent an aryl group or a heterocyclic residue. Ar 1 , Ar 2 , Ar 3 , Ar 4 are independent from each other, Ar 1 and Ar 2 , Ar 3 and Ar 4 are directly bonded to each other, or Ar 1 and Ar 3 , Ar 3 and Ar 4 are Binding is through either oxygen (O) or sulfur (S) or a carbonyl group. |
