  Low-Temperature and Wide Ferroelectric Phase in Mixtures of Chiral and Non-Chiral Tilted Smectic C-Type Liquid Crystals

  摘要：

  A new liquid crystal of siloxane dimer with an achiral swallow-tail, C11Si3C11, was synthesized and mixed with a chiral material of 4'-(1-butoxy-1-oxopropan-2-yloxy)biphenyl-4-yl 3-bromo-4-[9-(1,1,2,2,3,3,3-hepta-methyltrisiloxanyl)nonyloxy) benzoate, C9SiFLC, for the preparation of binary mixtures for the study. The mesophases under discussion were investigated by means of polarizing microscopy (POM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and electro-optical experiments. The influence of the mixture proportion of C9SiFLC on the occurrence of the chiral smectic C (SmC*) phase was investigated. Finally, the electro-optical properties of the SmC* phase, such as the tilt angle and switching behavior, were also measured.
