The present invention provides a benzene derivative having a long, linear conjugated structure, the benzene derivative being capable of exhibiting a satisfactory ability to transport charge without photoexcitation, a process for producing the benzene derivative, and a liquid-crystal material and a charge-transport material containing the benzene derivative having a long, linear conjugated structure. That is, a benzene derivative having a long, linear conjugated structure represented by general formula (1): ##STR00001## (wherein R.sup.1 represents a methyl group or a hydrogen atom, A represents an alkylene group, --CO--O--(CH.sub.2).sub.n--, --C.sub.6H.sub.4--CH.sub.2--, or --CO--).
