A re-entrant polymorphism N SA SC Nre

Abstract
The polymorphism of a new series 4-[-4"-alkoxy-cinnamoyloxy] benzylidene-4'-cyano-aniline was studied and a re-entrant nematic phase was observed for the three homologues n = 8, 9, 10. The decyloxy compound exhibits the unusual N SA SC N re sequence. For the first time, phase diagrams connected with X-ray analysis confirm this result. The partial bilayer SC notion is introduced
