Abstract:
The present invention is directed to the provision of a novel liquid crystalline organic semiconductor material that is highly stable under an film forming environment and, at the same time, can easily form a film, for example, by coating. The liquid crystalline organic semiconductor material is represented by chemical formula 1 wherein R1 and R2 represent an identical alkyl group having 7 to 20 carbon atoms: There is also provided a liquid crystalline organic semiconductor material characterized by being represented by chemical formula 2 wherein R3 and R4 represent an identical alkyl group having 7 to 20 carbon atoms:
