Eight hexa-n-alkanoyloxy truxenes are presented. These new disc-like liquid crystals exhibit both columnar and N D nematic phases. The N D nematic phase is the first low temperature one. All these compounds show an inverted nematic-columnar sequence: the fluid N D nematic phase is observed while heating after the crystalline phase below one or two viscous columnar phases and shows a phenomenon quite similar to the reentrant nematic behaviour.
