摘要

Disclosed are: a benzodithiophene derivative having an aromatic hydrocarbon group or an aromatic heterocyclic group in its center; an organic thin film transistor which has, ON a substrate, at least three terminals and i.e., a gate electrode, a source electrode and a drain electrode, an insulating layer, and an organic semiconductor layer, and in which the current flowing between the source electrode and the drain electrode is controlled by applying a voltage to the gate electrode and wherein the organic semiconductor layer comprises a specific benzodithiophene having an aromatic hydrocarbon group or an aromatic heterocyclic group in its center; and an organic thin film light-emitting transistor substantially comprising the organic thin film transistor and wherein the emission of light is achieved by utilizing the current flowing between the source electrode and the drain electrode and controlled by applying a voltage to the gate electrode. It becomes possible to provide: an organic compound that exhibits a highly stable field effect mobility even when being exposed to the atmosphere; and an organic thin film transistor and an organic thin film light-emitting transistor each utilizing the organic compound.
