Title

Dielectric Anisotropy and Rotational Viscosity of the Twisted Grain Boundary Phases of the Homologous Series of 4-n-alkyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone

Abstract

The present research article deals with the comparative thermodynamical and electrical studies of the compounds 4-n-decyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 10), 4-n-undecyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 11) and 4-n-dodecyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (DC-4, 12) in order to generalize the electrical (mainly dielectric anisotropy, experimental slopes of inverse of dielectric strength with temperature and rotational viscosity) behaviors of the Twisted Grain Boundary (TGB) phases. The research article also explores the effect of the increase in the length of the alkyl chains on the dielectric properties of the above studied compounds. A series of the nonsymmetrical liquid crystal (LC) dimers derived from cholesterol have been synthesized by Yelamaggad and co-workers at Centre for Soft Matter Research, Bangalore, India [1]. They have reported independent occurrence of the twisted grain boundary (TGB) phases. The homologous series of 4-n-alkyloxy-4'-(cholesteryloxycarbonyl-1-butyloxy) chalcone (with tail length = 10, 11, 12) demonstrate exceptionally wide temperature range TGBA ( 15-19 C) and TGBC* ( 23-33 C) [1, 2].
