THIENOPYRAZINE COMPOUND AND FIELD EFFECT TRANSISTOR CONTAINING SAME

摘要

Disclosed is a thienopyrazine compound which is useful for an organic semiconductor material. Also disclosed are: an organic field effect transistor, which comprises an organic semiconductor layer that is easily produced from an organic semiconductor material containing the thienopyrazine compound by a coating method or a printing method, and which exhibits high carrier mobility and high on/off current ratio; and an organic field effect transistor which has ambipolar characteristics. The thienopyrazine compound is represented by the chemical formula (I)
wherein Ar 1 and Ar 2 each represents an aryl group, and R 1 and R 2 each independently represents a hydrogen atom, an alkyl group or an aryl group; or alternatively R 1 and R 2 represent a group having a ring formed by combining R 1 and R 2 together.
