    • A diacetylene derivative was used as a starting material, and was subjected to dilithiation using an organolithium reagent. The resulting product was allowed to react with an excessive amount of chalcogen. Accordingly, an intramolecular cyclization reaction proceeded simultaneously with formation of skeletons of three rings. As a result, a chalcogen-containing fused polycyclic organic material was found to be obtained which has the three rings and a dichalcogenid bond. Further, by subjecting the resulting compound to a dechalcogenation reaction, a heteroacene was found to be obtained in a satisfactory yield. These synthetic techniques have made it possible to synthesize a series of highly planar chalcogen-containing π-electron system materials. Therefore, it is possible to provide (i) a chalcogen-containing fused polycyclic organic material capable of exhibiting excellent charge-transporting properties and (ii) a method for producing the material.
    • 使用乙炔衍生物作为起始原料,并使用有机锂试剂进行稀释。 使所得产物与过量的硫属元素反应。 因此,分子内环化反应与三环骨架的形成同时进行。 结果发现具有三环和二硫键键的含硫属化合物的稠合多环有机材料。 此外,通过使所得化合物进行脱钴反应,发现以良好的产率获得了异。。 这些合成技术使得可以合成一系列具有高平面含硫属元素的pi电子系统材料。 因此,可以提供(i)能够表现出优异的电荷输送性的含硫属原子的稠合多环有机材料,(ii)制造该材料的方法。
