Paper Title:
Photo-Instability in a Binary Mixture of Banana-Shaped and Rod-Shaped Liquid Crystals
  Abstract

By triangular wave method, we studied the effects of ultraviolet irradiation on the polarization of a binary liquid crystal mixture. The mixture was comprised of 94 wt% of banana-shaped liquid crystal 4-chloro-1,3-phenylene bis [4-(4-n-tetradecyl) phenylimino methyl] benzoate and 6 wt% of an azo-containing rod-shaped liquid crystal hexanoic acid 4-(4-ethoxy-phenylazo)-phenyl ester. Under the 365 nm irradiation for 40 minutes, the polarization of the mixture was observed to decrease 10% although the component of the banana-shaped liquid crystal was photostable. Our results demonstrated that photolysis took place in the component of azo-containing rod-shaped liquid crystal.
