Photostability of an Antiferroelectric Banana-Shaped Liquid Crystal
We have investigated the photostability of an antiferroelectric banana-shaped liquid crystal 4-chloro-1,3-phenylene bis [4-(4-n-tetradecyl) phenylimino methyl] benzoate by measuring its polarization as a function of photo-irradiation duration. Upon intense photo-irradiation for three hours, the banana-shaped liquid crystal exhibits a significant photostability although it bears the linkages of –COO– and –CH=N–.
