    • 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.
    • 在本发明的一个实施方案中,本发明的新型稠合多环芳香族化合物是(a)还含有位于BXBX骨架外侧的芳香环的苯并二硫代苯并苯并二硫代苯并(BXBX)骨架的化合物,或(b) 包括其中苯环被杂环取代的BXBX骨架的化合物。 该化合物可以增强分子间的相互作用, 电子轨道。 这提高了通过使用化合物作为有机半导体材料制造的有机半导体器件的电子场效应迁移率。 此外,由于化合物中包含的稠合环的数量少,所以化合物不会产生通常发生在具有极大数目的稠环的化合物中的问题,即在溶剂中的溶解性差和由于高亲和力而导致的差的大气稳定性 氧。 结果,本发明的稠合多环芳族化合物可以优选用作有机半导体材料。
