There is provided a compound which provides a semiconductor material. The compound is represented by General Formula (1)  wherein Ar represents an aryl group which may have a substituent or a heteroaryl group which may have a substituent, and Rrepresents an acyclic alkyl group having 1 to 20 carbon atoms wherein hydrogen atom in the alkyl group may be replaced by a halogeno group, a nitrile group or an aryl group, and &#x2014;CH&#x2014; in the alkyl group may be replaced by &#x2014;O&#x2014;, &#x2014;R'C&#x2550;CR&#x2032;&#x2014;, &#x2014;CO&#x2014;, &#x2014;OCO&#x2014;, &#x2014;COO&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;SO&#x2014;, &#x2014;NH&#x2014;, &#x2014;NR&#x2032;&#x2014; or &#x2014;C&#x2261;C&#x2014; provided that, with respect to each of an oxygen atom, a sulfur atom and a nitrogen atom, the same atoms are not directly bonded to each other, wherein R&#x2032; represents an acyclic or cyclic alkyl group having 1 to 20 carbon atoms.

Compound and semiconductor material containing same

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).
