Organic semiconductor material, organic semiconductor thin film and organic semiconductor device

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 R1 to R10 may be independently the same substituents or different substituents but all of R1, R4, R5, R6, R9 and R10 may never be hydrogen atoms at the same time, and where each of R1 to R10 is 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.

AI Technical Summary

Problems solved by technology

[0020] As described above, although polyacene compounds are compounds that are expected to exhibit excellent functions as organic semiconductor materials, polyacene compounds are difficult to dissolve at low temperatures (such as room temperature), and thus are not suitable for coating methods such as spin coating.
