Title CHALCOGEN-CONTAINING FUSED-RING POLYCYCLIC ORGANIC MATERIAL AND PROCESS FOR PRODUCING THE SAME
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 (S, Se). 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 À-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.
