  Synthesis, Characterization, and Electro-Optic Properties of Novel Ferroelectric Liquid Crystal with a Large Tilt Angle and Wide Temperature Range of Chiral Smectic C Phase

  摘要：

  The present article is a study of the ferroelectric behavior in low-molar-mass organosiloxane liquid-crystal materials classed. A few novel compounds with large tilt angle and wide temperature range of the SmC* phase have been synthesized, and the mesophases exhibited by them have been compared. The mesophases under discussion were investigated by means of polarizing microscopy, differential scanning calorimetry, X-ray diffraction, as well as electro-optical experiments. The influence of the molecular structure on the occurrence of the SmC* phase was investigated. Finally, the electro-optical properties of the SmC* phase, such as tilt angle, dielectric permittivity, and switching behavior, were also measured. As a consequence, the correlation between their electro-optical properties and chemical structures of these compounds is investigated.

  The present invention relates to photo-crosslinkable liquid crystal monomers with optical activity. The liquid crystal monomers contains one chiral center with an acrylate group or terminal diacrylate groups, and terminal dibenzene rings are introduced in order to extend its hard segment for the purpose of getting a wider liquid crystalline phase. By introducing the liquid crystal monomers, the room temperature nematic liquid crystal or the cholesteric liquid crystal may have a better mutual solubility and a wider, steadier structure of liquid crystal. The liquid crystal monomers have the following formula structure:

Both relate to the odd−even rules for chiral sense changes in liquid crystalline phases. The role of noncovalent interactions in the polymerization has been proven by performing the reactions at various concentrations and in different solventsthe
