  2-Trifluoromethyl-1,3-dithianylium triflate: a convenient ‘masked’ electrophilic pentafluoroethylation reagent

  摘要：

  With 2-trifluoromethyl-1,3-dithianylium triflate for the first time the synthesis, isolation and full structural characterization of an alpha-perfluoroalkylcarbenium salt was achieved. The title compound can be easily obtained on a preparative scale. The thermally stable dithianylium salt in combination with fluorodesulfurization chemistry is a promising novel reagent for the electrophilic polyfluoroalkylation of organic substrates, demonstrated by the pentafluoroethylation of O-nucleophiles.

  A large number of new liquid crystals incorporating the 2,5-disubstituted thiophene ring have been prepared and their mesomorphic behaviour studied in order to systematically investigate the correlation between the molecular structure and mesomorphism of thiophene derivatives with different shapes, polarisability and polarity. As a consequence of these investigations we have prepared a new class of liquid crystals incorporating a 2,5-disubstituted thiophene ring and a conjugated trans-carbon–carbon double bond in the terminal chain. These novel thiophene derivatives are the first liquid crystals incorporating a 2,5-disubstituted thiophene ring to exhibit a nematic phase at room temperature. This enables the flexoelectric coefficients of a bent-shaped molecule to be measured directly and at room temperature for the first time to the authors' knowledge. Many of these new thiophenes exhibit a high birefringence and a high nematic clearing point and are of potential use as components of nematic mixtures in LCDs.

  制备了大量含有2,5-二取代噻吩环的新型液晶，并研究了它们的介晶行为，以系统地探讨不同形状、极化能力和极性的噻吩衍生物的分子结构与介晶性之间的关联。通过这些研究，我们合成了一类新型液晶，它们含有2,5-二取代噻吩环和末端链中的共轭反式碳-碳双键。这些新颖的噻吩衍生物是首批在室温下表现出向列相的含有2,5-二取代噻吩环的液晶。这使得弯曲形状分子的挠曲电系数能够首次在作者所知的情况下直接在室温下测量。许多这些新型噻吩具有高双折射率和高向列相清亮点，有可能作为液晶显示器中向列相混合物的成分。
• A Facile Synthesis of Novel Liquid Crystalline Materials Having a Trifluoromethoxy Group and Their Electro-Optical Properties

  Novel liquid crystals (LCs) containing a trifluoromethoxy group connected to a cyclohexane mesogen or to an alkyl tail were prepared through an oxidative desulfurization-fluorination reaction of the corresponding dithiocarbonates. They were compared with LCs containing a methoxy group with respect to phase transition behavior and physical and electro-optical properties. Most of the CF3O-substituted LCs exhibited in a wide range of temperatures LC phases depending on the type of a mesogenic structure. LCs with a trifluoromethoxycyclohexane mesogen were shown to be thermally more stable than the LCs with a trifluoromethoxybenzene mesogen. LCs having a trifluoromethoxyalkyl tail show physical and electro-optical properties favorable to materials for not only TN-LCDs but TFT-addressed TN-LCDs. Furthermore, 3-β-CF3O-substituted cholestane was shown to be a potential chiral dopant for TFT-addressed TN-LCDs.

  通过对相应的二硫代碳酸酯进行氧化脱硫-氟化反应，制备了含有与环己烷介质或烷基尾部相连的三氟甲氧基的新型液晶。在相变行为、物理和电光特性方面，它们与含有甲氧基的低聚物进行了比较。大多数 CF3O 取代的低聚物在不同的温度范围内表现出低聚物相，这取决于介源结构的类型。结果表明，具有三氟甲氧基环己烷中间体的低聚物比具有三氟甲氧基苯中间体的低聚物具有更高的热稳定性。具有三氟甲氧基烷基尾部的低聚物不仅显示出有利于 TN-LCD 材料的物理和电光特性，还显示出有利于 TFT-addressed TN-LCD 材料的物理和电光特性。此外，3-β-CF3O 取代的胆甾烷被证明是一种潜在的手性掺杂剂，可用于 TFT-addressed TN-LCD。
