  Synthesis and Characterization of Symmetrical Eight Aromatic Ring Containing Bent-Shaped Material Derived from Benzophenone

  摘要：

  A new family of symmetrical eight aromatic ring-containing bent-shaped mesogens in which the central elbow is a ketone has been synthesized and characterized. The effect of the side chain on the mesomorphism has been studied. All the bent derivatives were found to exhibit mesomorphism. The higher homologues of the series exhibit the B1 phase and the lower homologues of the series show the B6 phase.

  rod‐like compounds. In all compounds studied the cubic phase is always chiral, while the phase is achiral. These intriguing observations are explained by propagation of homochiral helical twist across the entire networks through helix matching at network junctions. In the phase the opposing chiralities of the two networks cancel, but not so in the three‐networks phase. The high twist in the phase explains

  自巴斯德以来，在有序晶体超结构中自组装过程中非手性分子的对映异构体或手性构象异构体的手性分离一直令化学家着迷。在这里，我们报告了由非手性多链封端的二苯基-2,2'-联噻吩形成的立方相的自发镜像对称破坏。发现随机对称破坏是在非手性棒状化合物的双连续立方液晶相中观察到的普遍现象。在所有研究的化合物中，立方相总是手性的，而该相是非手性的。这些有趣的观察结果是通过网络连接处的螺旋匹配在整个网络中传播同手性螺旋扭曲来解释的。在里面阶段两个网络的相反手性取消，但在三网络阶段则不然。该相的高扭曲解释了其先前未被认识的手性，以及这种复杂结构的起源和不同立方相之间的转变。
• Bent-core liquid crystal (LC) decorated gold nanoclusters: synthesis, self-assembly, and effects in mixtures with bent-core LC hosts

  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。

  The synthesis and mesomorphic properties of a new series of bent-shaped liquid crystals based on 3-hydroxycinnamic acid are presented. Prepared compounds differ in the orientation of an ester linking group in one of the side arms. Additionally, the mesomorphic properties have been tuned by employing either an alkoxy or carboxylic terminal group and by varying the length of terminal alkyl chains. Texture
