Benzene derivative having a long linear conjugated structure part, a process for producing the same, liquid crystalline material and charge transporting material

摘要

Benzene derivative having a novel long linear conjugated structure part which exhibits excellent charge transporting ability even without photoexcitation, a process for producing the same, liquid crystalline material containing a benzene derivative having the long linear conjugated structure part and charge transporting Material. That is, the following general formula (1) (Wherein R¹Is a methyl group, a hydrogen atom, A is an alkylene group,-CO-O-(CH₂)_N-,-C₆H₄-CH₂-,-CO-. The benzene derivative of the present invention is a benzene derivative having a long linear conjugated system structural moiety.
