Disclosed are a novel compound having good electron mobility, a process for producing the compound, an organic semiconductor material containing the compound, and an organic semiconductor device. The respective novel compounds have a structure comprising naphthalene and a thiophene ring or a selenophene ring bonded to each of two benzene rings in the naphthalene, as represented by general formula (1), (2), (3), or (4) wherein Z represents a sulfur atom or a selenium atom; and R represents a hydrogen atom, an alkyl group, or a phenyl group. Each of the compounds has a conjugated system within each molecule derived from an interaction between p orbits, and exhibits a strong molecule interaction through a sulfur atom or a selenium atom contained in the thiophene ring or the selenophene ring in each molecule. Thus, the compound has a good electron mobility. |
