Effect of Molecular Structure of Core on Ferroelectricity in Ferroelectric Liquid Crystals

Abstract
By using various couples of ferroelectric liquid crystals with molecular structures which were only different in the core center in each couple, the effect of the bond moment C=O at the center of core on ferroelectricity could be studied. The bond moment C=O at the center of the core was found to enhance the spontaneous polarization except for one case.
