Abstract
An organic semiconductor material is provided. The organic semiconductor material includes a polyacene derivative expressed by the following general formula (1): where each of Rto Rmay be independently the same substituents or different substituents but all of R, R, R, R, Rand Rmay never be hydrogen atoms at the same time, and where each of Rto Ris at least one kind of substituent selected from the group consisting of an aliphatic hydrocarbon group having a substituent and of which number of carbon atoms ranges of from 1 to 20, an aromatic hydrocarbon group having a substituent, a complex aromatic group having a substituent, a carboxyl group, a hydride, an ester group, a cyano group, a hydroxyl group, a halogen atom and a hydrogen atom. The organic semiconductor material can be dissolved into an organic solvent at low temperature (for example, room temperature) and is suitable for use with a coating process.
