Quinoxaline derivatives, and organic semiconductor devices, electroluminescent devices made by using the derivatives

摘要

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 1 - R 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 9 and R 10 , R 10 and R 11 , and R 11 and R 12 are each independent or respectively mutually bonded to form an aromatic ring. Ar 1 - Ar 4 each independently represents an aryl group or a heterocyclic residue group. Ar 1 , Ar 2 , Ar 3 and Ar 4 are each independent or Ar 1 and Ar 2 , and Ar 3 and Ar 4 are respectively mutually bonded directly, or Ar 1 and Ar 3 , and Ar 3 and Ar 4 are bonded via oxygen (O), sulfur (S) or a carbonyl group.
