Abstract
Provided are a compound which is excellent in solubility in a solvent and easily provides a film exhibiting high mobility without complicated processes, an organic semiconductor material using the same, and an organic semiconductor ink which enables easy fabrication of an organic transistor composed of a practical configuration. The problems are solved by a method of producing a dinaphthothiophene derivative, the method including the following steps (I) and (II): (I) a first step of subjecting a naphthol derivative represented by General Formula (A) and a naphthalene thiol derivative represented by General Formula (B) to dehydration condensation in the presence of acid to produce a sulfide derivative represented by General formula (C); and (II) a second step of performing dehydrogenation reaction of the sulfide derivative (C) in the presence of a transition metal salt or a transition metal complex to produce a dinaphthothiophene derivative (D).
