The homologous series of an alkoxyazobenzene-triphenylene system (CnTEsAz) in which six alkoxyazobenzenes are attached to triphenylene via propyleneester linkage were synthesized to study their mesomorphism. DSC and XRD measurements in addition to the optical texture observation clarified these homologues to be mesomorphic showing bimesomorphy of calamitic smectoic and discotic columnar mesophases in an enantioropic way.
