Abstract

Synthesis and study of the effect of positional Isomerism on Liquid Crystal Behavior of the series: Methyl-o-[ p'-n-alkoxy benzoyloxy] benzoates

Author(s): Doshi A.V. Joshi C.G. and Vyas N.N.

Homologous series Methyl-o-[p’-n-alkoxy benzoyloxy]benzoates was synthesized with a view to understand and establish the effect of molecular structure on liquid crystal[LC] properties in positionally isomeric molecules. Totally ten homologues are synthesized. Methyl and ethyl derivatives of the series are nonliquidcrystals, propyl to hexyl and octyl derivatives are enantiotropic nematic, decyl derivative is polymesomorphic , i.e. exhibits enantiotropic nematic mesophase in addition to enantiotropic smectic mesophase as well as dodecyl and tetradecyl derivatives are enantiotropic smectic. Transition temperatures are determined by hot stage polarizing microscope. Analytical data support the structure. Texture of the nematic mesophase is threaded or schlieren type. Liquid crystal properties of titled series are compared with structurally isomeric series.
