Abstract
An organic semiconductor material is represented by the following formula (F): wherein A represents a cyclic conjugated skeleton structure formed of one or more aromatic rings, and R1 and R2 each independently represent a substituted or unsubstituted alkyl group. The organic semiconductor material has high electron mobility and high on/off ratio, and can form an organic semiconductor thin film by a solution process making use of its solution.
