Abstract:
An aspect of the present invention provides the dibenzothiophene compound expressed by General Formula 1 in Claim 1. In General Formula 1, R1 is either a hydrogen atom or an unsubstituted phenyl group, and Ar1 is any of phenanthrenyl, fluorenyl, triphenylenyl, naphthyl, chrysenyl, and pyrenyl groups. The options for the Ar1 substituents, namely the phenanthrenyl, fluorenyl, triphenylenyl, naphthyl, chrysenyl, and pyrenyl groups, may contain at least one of an alkyl group having one to four carbon atoms and an aryl group as a substituent.
