METHOD FOR PRODUCING ORGANIC THIN FILM AND ORGANIC SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an organic semiconductor device having not only high mobility but also high performance stability, and a method for producing an organic thin film that is useful for an organic transistor.SOLUTION: In a method for producing an organic thin film that is formed from a compound including a charge transport molecule unit A having an aromatic condensed ring structure and a unit B as a side chain, the compound is dissolved in a mixed solvent comprising an aromatic solvent (A) and an organic solvent (B) having a boiling point lower than that of the aromatic solvent (A), and then coated.
