  含硅多亲弯曲核分子：纳米偏析对于非手性分子形成的液晶相中手性和极性顺序发展的重要性

  摘要：

  合成了由弯曲的芳香核、低聚（硅氧烷）单元和烷基链段组成的多亲分子，并研究了这些分子的自组织。大多数材料组织成极性近晶液晶相。这些中间相的转换过程从非甲硅烷化化合物的反铁电通过超顺电转变为表面稳定的铁电，随着甲硅烷化链段的分离增加。提出硅氧烷亚层稳定极性向斜铁电（SmC（s）P（F））结构，并且从宏观极性顺序以及空间效应的逃逸导致层变形，形成无序微畴，产生光学各向同性。另一个显着特征是具有相反旋向性的手性域的自发形成。对于两种化合物，发现这些域的旋光度随温度而变化，这与分子倾角从 < 45 度增加到 > 50 度有关。这一观察证实了最近提出的层光学手性概念（Hough, LE; Clark, NA Phys. Rev. Lett. 2005, 95, 107802），这是超分子系统中光学活动的新来源。随着烷基链长度的增加，偏析消失并且发现从近晶相到柱状相的转变。在柱状相中，转换过程是反铁电的

  About twenty substituted phenyl benzoates incorporating a trans-4-pentylcyclohexyl moiety have been synthesised. The synthesis, liquid-crystal transition temperatures, and enthalpies of fusion are reported. The effect of variations in chainlength and central linkage on the liquid-crystal transition temperatures is discussed.

• 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。

  Chiral, smectogenic pendant groups have been covalently attached to cyclic oligosiloxanes by hydrosilylation. These materials and the olefinic compounds from which they were derived exhibit ferroelectric behavior. The mesomorphic range, and in particular the S C * phase, of these oligomers is greatly enhanced relative to the vinylogous parents. The electro-optic and thermal properties, in addition to the synthetic procedures used to prepare these materials, are described in detail. These compounds are seen as potential precursors to liquid crystalline polymers with desirable processing capabilities.
