Synthesis, Characterisation and Phase Transition Studies of 50.9 and 90.5

Abstract

Abstract The synthesis, characterisation of phases of the compounds N(p‐n‐pentyloxy benzylidene) p‐n‐nonylaniline, 50.9 and N(p‐n‐nonyloxy benzylidene) p‐n‐pentylaniline, 90.5 and phase transition studies using different experimental techniques are presented. The compound 50.9 exhibits a phase sequence NAB whereas 90.5 shows a phase variant ABG. A large density jump across IN transition is observed in 50.9 similar to that observed in 50.10 compound.
