  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.

  A new series of liquid crystalline dimers with exceptionally high apparent tilt

  摘要：

  我们合成了一系列新的二聚手性反铁电材料，这些材料使用三硅氧烷作为中心连接物，并具有氟化尾部及其相应的单体。使用的间隔长度为 3-6 和 11 个亚甲基。为了比较硅氧烷长度对相行为的影响，还合成了一种以四硅氧烷为核心的二聚体。间隔碳数为 3-6 个的单体只显示出正交的平滑相，只有 11 个碳的长间隔碳 7F4PPB11 显示出倾斜相，与之前研究的无氟单体非常相似。所有三硅氧烷都显示出高温反铁电相，而那些具有 4 个或更多碳间隔长度的三硅氧烷在降低温度时也显示出一个或两个柱状反铁电相。自发极化 Ps 很高，尤其是在柱状相中，其范围在 800-1200 nC cm-2 及以上。所有研究材料的视倾角都非常高，超过 45 度。与之前描述的趋势一致，含有四硅氧烷的二聚体在高温下呈现铁电相。但在这种情况下，柱状相被发现是反铁电相。因此，三硅氧烷核心促进反铁电性，而四硅氧烷促进铁电相的一般观点对于这些处于 SmC* 相的材料来说仍然是正确的，但对于柱状相来说并不正确。我们还注意到，分子中硅氧烷、氟化尾部和介电部分之间的相分离程度非常高，以至于在降低温度时材料会变成柱状。

  A liquid-crystalline polymer comprising the repeating units of the general formula (I) in which : k is an integer from 1 to 30 ; and R1 is where : X is -COO-or -OCO-: and R2 is -COOR3, OCOR3, or -OR3 where : R3 is R4 and R5 being each independently -CH3, a halogen radical, or -CN, m and n being each independently an integer from 0 to 10 with the proviso that n is not 0 when R4 is -CH3, p being 0 or 1, and C marked with being an asymmetric carbon atom. The polymers of the present invention exhibit a ferroelectricity even at temperatures around room temperature and as well have such a high speed of response to external factors that they can be used for displaying motion pictures, and the polymers may also be advantageously used as display elements for large displays or curved displays.

• Shear Deformation and Ferroelectricity in Chiral SmC* Main-chain Elastomers
  作者：Patrick Heinze、Heino Finkelmann

  DOI：10.1021/ma1002084

  日期：2010.8.24

  Ferroelectric smectic main-chain liquid crystalline elastomers were synthesized and subjected to simple shear deformation to achieve reorientation of the layer structure and the formation of a macroscopic spontaneous polarization. The phase behavior and structural parameters of these elastomers are investigated and discussed. A shear-induced splitting of the X-ray scattering intensity distribution is found. A splitting of the sample in domains of two director orientations that couple differently to the shear deformation is proposed. The smectic layers also move at different affinities depending on their initial orientation. The smectic layer spacing was found to be nearly constant even though the smectic tilt angle changes significantly. The realignment of the smectic layers indicates a migration process, where depending on their original orientation the layer normals are leaving or entering the X-ray scattering plane. The spontaneous polarization was found lobe linearly dependent on the dopant concentration with Ps = 30 nC/cm(2) for a system doped with 11 wt % of chiral dopant.
