In one embodiment of the present invention, a novel fused polycyclic aromatic compound of the present invention is (a) a compound including a benzodichalcogenophenobenzodichalcogenophene (BXBX) skeleton further having an aromatic ring(s) located outside the BXBX skeleton, or (b) a compound including a BXBX skeleton in which a benzene ring is substituted with a heterocyclic ring. The compound can strengthen intermolecular interaction due to greater π electron orbits. This improves an electron field effect mobility of an organic semiconductor device that is manufactured by use of the compound as an organic semiconductor material. Further, since the number of fused rings included in the compound is small, the compound does not cause problems that generally occur in compounds having an extremely large number of fused rings, i.e., poor solubility in solvent and poor atmospheric stability due to high affinity to oxygen. As a result, the fused polycyclic aromatic compound of the present invention can be preferably used as an organic semiconductor material.
A method for producing a heterocyclic compound represented by general formula (2) from a heterocyclic compound represented by general formula (1) (in the formulae, X1 represents a halogen atom; each of Y1 and Y2 independently represents an oxygen atom, sulfur atom, or selenium atom; each of R1 and R2 independently represents a substituent; m and n respectively represent the number of substituents R1 and R2, each of m and n representing an integer of 0-4; and when m and n are 2 or higher, R1 and R2 may be the same or different and may bond to each other to form an optionally substituted ring).
