| 摘要 |
An organic thin film transistor including a substrate having thereon at least three terminals of a gate electrode, a source electrode and a drain electrode, an insulator layer and an organic semiconductor layer, with a current between a source and a drain being controlled upon application of a voltage to the gate electrode, wherein the foregoing organic semiconductor layer includes a specified organic compound having an aromatic hydrocarbon group or an aromatic heterocyclic group and an acetylene structure in the center thereof; an organic thin film light emitting transistor in which in the organic thin film transistor, light emission is obtained utilizing a current flowing between the source and the drain, and the light emission is controlled upon application of a voltage to the gate electrode; an organic thin film transistor which is made high with respect to the response speed and has a large ON/OFF ratio by a compound suitable therefor; and an organic film light emitting transistor utilizing it, and a compound suitable therefor, are provided.
