Synthesis and study of Ester Mesogenic Homologous Series: Ethyl-o-[p'-n-alkoxy benzoyloxy]benzoates

Author(s): Doshi A.V, Joshi C.G. and Bhoya U. C.

Ester homologous series Ethyl-o-[p’-n-alkoxy benzoyloxy]benzoates was synthesized by condensing p-n-alkoxy benzoyl chloride with o-hydroxy ethyl benzoates in pyridine. Work was planned to synthesize new liquid crystal material with a view to understand the effect of structural variation on liquid crystal [LC] or mesogenic character. Series consists of eleven homologues in which butyl to hexyl, octyl, decyl derivatives are enantiotropically nematogenic only, dodecyl derivative is enantiotropic Smectic in addition to nematogenic character, tetradecyl and hexadecyl derivatives are enantiotropic smectic only. Phase behaviour and mesogenic properties are determined from phase diagram drawn from the transition temperatures of the homologues observed using hot stage polarizing microscope. Texture of nematic mesophase is threaded or schlieren type and that of the smectic mesophase is focal conic fan shaped of A or C type. Mesophase length ranges from 5.0 oC to 44.0 oC with middle ordered melting type. Analytical data support the structure. Mesogenic properties are compared with structurally similar homologous series.
