  Liquid crystalline properties of unsymmetrical bent-core compounds containing chiral moieties

  摘要：

  报告了含有手性分子的新型非对称弯曲核化合物的合成、表征和介形性质。这些化合物以 3-羟基苯甲酸或 2,7-二羟基萘为中心单元。手性基团或作为连接基团加入到弯曲核心结构中，或附加在末端位置。我们研究了手性基团的位置对介形性质的影响。在末端链中含有手性基团（辛烷-2-醇）的弯曲核化合物表现出随着温度的降低，从手性钙钛矿相（如 SmC*、SmC*γ）直接过渡到具有二维晶格的极性香蕉相（ColobPA*）。为了证明这一相序，我们合成了末端链上带有外消旋辛烷-2-醇基团的相应化合物。初步观察和研究结果与手性化合物进行了比较。在 X 射线和电场实验的基础上，还讨论了这种不寻常相序的可能解释以及 ColobPA* (SmSPA*) 相的模型。

  Mesomorphism Behavior of Two Series of Chiral Compounds with Semiperfluorocarbon Chains

  摘要：

  Thermotropic liquid crystals with fluorocarbon chains have attracted much attention, because they are feasible to form smectic phases. Herein, two series of chiral compounds with semiperfluorocarbon chains were designed and synthesized. These compounds were characterized by IR, H-1 NMR, F-19 NMR, mass spectroscopy, and elemental analysis. Phase transition behavior was investigated by differential scanning calorimetry and polarized optical microscopy. Members of the two-ring series do not exhibit liquid crystalline phases. However, the three-ring analogues exhibit an enantiotropic SmA phase. When the length of alkyl chains is sufficient, an enantiotropic SmB phase is also identified.

  Two series of chiral compounds with semi-perfluorocarbon chains and alkoxy ones, nBP4F and nBP6F, are synthesized. Enantiotropic SmA phase is identified in all of these compounds. When the alkoxy chain length is short, enantiotropic SmB is also identified. When the alkoxy chain length is longer than 6 carbons, enantiotropic SmC* phase is formed. Their clearing points increase with increasing the perfluorocarbon chain length. Comparison of compounds with -CF3, -CHF2 and -CF2Cl groups at the terminals of the fluorocarbon chains, the clearing point sequence is -CHF2 < -CF2Cl < -CF3; and the melting point sequence is -CF3 < -CHF2 < -CF2Cl. Therefore, the compounds with semi-perfluorocarbon chains show the widest liquid crystalline temperature range. Moreover, the SmC* phase of the compounds with -CF3 at the terminals shows the highest thermostability.
