  摘要：

  为了研究连接基团方向在弯核介素中的作用，我们合成了两个系列的十种可能的非手性异构五环弯核化合物，其中所有的芳香环都由酯基连接，每种化合物都具有相同长度的末端链（分别为辛氧基或十二氧基）。异构体的结构仅以至少一个酯基的方向来区分。我们通过偏光显微镜、差示扫描量热法、X 射线实验和电光测量等方法对这些化合物的介相行为进行了研究。我们发现，尽管结构上存在细微差别，但还是出现了多种介相（SmCPA、Colrec、Colob），其清除温度在 121 至 193 ℃（辛氧基异构体）和 112 至 189 ℃（十二烷氧基异构体）之间变化。根据酯基方向的不同，其中一些异构体显示出有趣的特性，如在 SmCPA 和柱状相中由场诱导的手性反转、由场诱导的清除温度升高、二阶相变 Colob → SmCPA 或可逆的场诱导相变 Colob → SmCPF。在对孤立分子进行理论计算和分子动力学模拟的基础上，讨论了连接基团方向意想不到的强烈影响。

  Novel thiol-terminated bent-core liquid crystals (LCs) are used to decorate gold nanoparticles. Thioacetate or xanthate/xanthogenate functional groups are used to effect the attachment of the LCs to the gold nanoparticles. Such bent-core decorated nanoparticles may be dissolved in bent-core liquid crystal host media to provide polarizable systems which respond quickly to applied electric fields and exhibit other interesting and useful optical and electro-optic behaviour.

  We present the first synthesis of a series of thiol-, thioacetate-, and xanthate-terminated bent-core derivatives, as well as the preparation of gold nanoclusters using the thiol-terminated bent-core compounds. The mesomorphic properties of the bent-core compounds have been investigated by polarizing optical microscopy (POM), differential scanning calorimetry (DSC), small angle X-ray scattering (SAXS), and electro-optic tests. From this series, the mono-xanthate derivatives form rectangular or hexagonal columnar phases, and the mono-thiol derivative with shorter alkyl chains forms a metastable, likely smectic, phase. All other bent-core compounds and intermediates exclusively form disordered or multi-layer lamellar crystalline solid modifications. High-resolution transmission electron microscopy (HR-TEM) images of the bent-core functionalized gold nanoclusters prepared from the thiol-terminated derivatives, taken after slow evaporation of the solvent, provide evidence for the formation of self-assembled nanocluster arrays. Upon dispersion of these gold nanoclusters in two structurally related bent-core LC hosts (one forming a SmCPA, and the second with a terminal double bond displaying a Colr phase), a shift in the surface plasmon resonance was observed indicating a LC host-dependent aggregation of the nanoparticles. Finally, we report initial results on the effects of different concentrations of these nanoclusters on the thermal properties as well as the applied voltage/current response of the parent SmCPA host.

  我们首次合成了一系列硫醇、硫代乙酸酯和黄原酸酯封端的弯核衍生物，并利用硫醇封端的弯核化合物制备了金纳米团簇。研究人员通过偏光光学显微镜（POM）、差示扫描量热仪（DSC）、小角 X 射线散射（SAXS）和电光测试研究了这些弯曲核化合物的介形态特性。在这一系列化合物中，单黄原酸酯衍生物形成了矩形或六角形柱状相，而烷基链较短的单硫醇衍生物则形成了一种易变相，很有可能是冶炼相。所有其他弯曲核化合物和中间体只能形成无序或多层片状结晶固体改性物。由硫醇端衍生物制备的弯曲核功能化金纳米簇在缓慢蒸发溶剂后拍摄的高分辨率透射电子显微镜（HR-TEM）图像证明了自组装纳米簇阵列的形成。将这些金纳米团簇分散在两种结构相关的弯曲核低聚物宿主（一种形成 SmCPA，另一种带有末端双键，显示 Colr 相）中时，观察到表面等离子体共振发生了变化，这表明纳米粒子的聚集取决于低聚物宿主。最后，我们报告了不同浓度的这些纳米团簇对热特性以及母体 SmCPA 宿主的外加电压/电流响应的影响的初步结果。

• Molecular Design of Nonchiral Bent-Core Liquid Crystals with Antiferroelectric Properties
  作者：Dong Shen、Annegret Pegenau、Siegmar Diele、Ina Wirth、Carsten Tschierske

  DOI：10.1021/ja993572w

  日期：2000.3.1

  Novel bent-core (banana-shaped) liquid crystals without Schiff-base units have been synthesized and investigated by polarized light optical microscopy, differential scanning calorimetry, X-ray scattering, and electrooptical investigations. These molecules are 4-(4-alkylbenzoyloxy)benzoates and 4-(4-alkoxybenzoyloxy)benzoates of resorcinol, 3,4'-dihydroxybiphenyl, and 4,4"-dihydroxy-1,1':3',1"-terphenyl. Three different mesophases were found depending on the molecular structure and the length of the terminal alkyl chains: a rectangular columnar phase, a highly ordered low-temperature mesophase, and an antiferroelectric switchable fluid smectic mesophase designated as SmCPA. The influence of the molecular structure on the occurrence of the SmCPA phase was investigated. The spontaneous polarization of these molecules is quite high (P-S = 500-700 nC cm(-2)) and specially those molecules with long alkyl chains and short bent-core structures have low melting points and broad regions of this switchable mesophase. Furthermore, first examples of antiferroelectric switchable bent-core molecules with semifluorinated terminal chains will be described.
