Abstract: 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.

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.
