  Novel Supramolecular Side-Chain Banana-Shaped Liquid Crystalline Polymers Containing Covalent- and Hydrogen-Bonded Bent Cores

  摘要：

  Novel supramolecular side-chain banana-shaped liquid crystalline (LC) polymer complexes AmBn-N bearing various (m/n) molar ratios of hydrogen- and covalent-bonded bent-core components were acquired by the free radical polymerization, where the hydrogen-bonded (H-bonded) structures were executed via mixing equimolar portions of proton donor (H-donor) polymers AmBn (homopolymers/copolymers) and pyridyl proton acceptor (H-acceptor) bent cores (small molecules). The influences of the molar ratios of bent-core H-bonded components in side-chain banana-shaped LC polymers and their corresponding polymer complexes on mesomorphic and electro-optical properties were first investigated. The voltage-dependent antiferroelectric properties of spontaneous polarization (Ps) values in the polar smectic phase of the supramolecular side-chain banana-shaped copolymers were also reported. The nematic and tilted smectic phases were verified by XRD measurements, and the SmCp phase was further confirmed by the triangular wave method. Suprinsingly, a novel enantiotropic polar smectic (SmCPA) phase was generated in some bent-core side-chain polymer complexes AmBn-N. Therefore, a special approach to constructing (or stabilizing) the SmCP phase was first developed in this study by copolymerization of bent-core covalent - and H-bonded units in side-chain polymer complexes (with proper m/n molar ratios of 16/1 and 10/1 from both bent-core covalent- and H-bonded monomers (i.e., B and A-N units, respectively) without the SmCP phase.

  摘要：

  报告了在一个臂中含有一个氟取代基的非对称五环弯曲核化合物的合成和介观性质。与具有两个氟取代基的对称化合物的性质比较表明，该取代基的位置对观察到的介相性质有影响。研究还提供了从矩形柱状（B1）相向反铁电层状（B2）相过渡的证据，这种过渡相当罕见。利用偏光显微镜、差示扫描量热法、X 射线衍射和电光研究对介相进行了表征。

  In order to study the role of the direction of the connecting groups in bent-core mesogens we synthesized two series of ten possible achiral isomeric five-ring bent-core compounds in which all aromatic rings are connected by ester groups and each of which possesses the same length of the terminal chains (octyloxy or dodecyloxy, respectively). The structure of the isomers is distinguished by the direction of at least one ester group, only. The mesophase behaviour of the compounds has been studied by polarizing microscopy, differential scanning calorimetry, X-ray experiments and electro-optical measurements. We have found that in spite of the minor structural differences a variety of mesophases occur (SmCPA, Colrec, Colob) whereby the clearing temperatures vary from 121 to 193 °C (octyloxy isomers) and 112 to 189 °C (dodecyloxy isomers). Depending on the direction of the ester groups some of these isomers show interesting properties, such as field-induced inversion of chirality in SmCPA and columnar phases, the field-induced enhancement of the clearing temperature, a second-order phase transition Colob → SmCPA or the reversible field-induced phase transition Colob → SmCPF. The unexpectedly strong influence of the direction of the connecting groups is discussed on the base of theoretical calculations and molecular dynamics simulation on isolated molecules.

  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。

  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。
