Abstract
Provided are an organic semiconductor material having a high charge mobility, oxidation stability, and solvent solubility, an organic semiconductor device using the same, and a novel aromatic heterocyclic compound to be used for the same and a production method therefor. The aromatic heterocyclic compound is represented by the following general formula (1), has two heteroatoms, and has a structure in which six rings are fused. In the formula, X represents an oxygen atom or N—R, and R represents hydrogen or a monovalent substituent. The organic semiconductor material contains the aromatic heterocyclic compound, and is used for an organic semiconductor film or an organic device, such as an organic thin-film transistor or an organic photovoltaic device.
