  间隔长度对包含 4-(4-甲氧基肉桂酰氧基)联苯侧基的可光交联液晶聚合物膜的光致重新取向行为的影响

  摘要：

  合成了含有4-(4-甲氧基肉桂酰氧基)联苯(MCB)侧基的甲基丙烯酸酯聚合物液晶，在聚甲基丙烯酸酯主链和MCB侧基之间具有不同的亚烷基间隔基长度。使用线性偏振紫外 (LPUV) 曝光和随后的退火研究亚烷基间隔物长度对薄膜的热增强分子重新取向行为的影响。当亚烷基间隔基短且诱导的面内有序参数大于0.6时，面内重新取向优先发生。另一方面，当亚烷基间隔物很长时，观察到热诱导的面外重定向以及面内重定向。

  Electrochemical characterization revealed that the liquid crystal phases favoured anhydrous proton conduction in the benzimidazole compounds and a proton conductivity of 4.4 × 10−5 S cm−1 was achieved at 173 °C. The temperature dependence of the proton conductivities approximately followed the Arrhenius law and the proton conduction in the benzimidazole liquid crystals was assumed to be dominated by the proton

  通过亲核取代反应合成了在苯甲酰胺链上带有在末端带有苯并咪唑部分的烷硫基链的同源系列化合物。在冷却过程中，这些化合物在173–116°C的温度范围内表现出近晶A相和向列相。在近晶组装体中形成了部分相互交叉的双层顺序，并且苯并咪唑部分之间的氢键沿着平行于近晶层的平面延伸。电化学表征表明，液晶相有利于苯并咪唑化合物中的无水质子传导，质子传导性为4.4×10 -5 S cm -1在173℃下达到。质子电导率的温度依赖性大致遵循阿伦尼乌斯定律，并且假定苯并咪唑液晶中的质子传导受质子跳变机理支配。
• Synthesis and characterization of new nematic liquid crystalline compounds-based thiophene units

  Four new liquid crystalline thiophene compounds (M1-M4) with a long flexible spacer were prepared. Their structures were characterized by Fourier transform infrared and proton nuclear magnetic resonance. The mesomorphism and thermal stability were investigated with differential scanning calorimetry, polarizing optical microscopy, and thermogravimetric analysis. The photo-physical properties were evaluated using ultraviolet/visible spectroscopy and photoluminescence. M1-M4 all showed thermotropic mesogenic properties with excellent thermal stability, and exhibited nematic threaded texture, droplet texture, and Schlieren texture on heating and cooling cycles. The effect of flexible spacer and terminal groups on mesomorphic and spectroscopic property is discussed. The experimental results demonstrated that the tendency toward melting temperature (Tm) decreased, while isotropic temperature (Ti) increased with increasing the flexible spacer length. In CHCl3 solution, these thiophene compounds displayed an intense broad absorption band peaking within 230-340nm and a maximum fluorescent emission wavelength at 426-439nm.
• Synthesis and Thermally Enhanced Photoinduced Orientation of Liquid Crystalline Polymer Possessing Vinyl End Group

  日期：2007.8.10

  Methacrylate polymer liquid crystals containing p-substituted 4-cinnamoyloxybiphenyl (CB) side group were synthesized. Two vinyl end groups were introduced to investigate the influence of the end group on the photoinduced reorientation behavior. Thermally enhanced photoinduced orientation of polymer thin films was performed by irradiating with linearly polarized ultraviolet (LPUV) light and annealing. The reorientation behavior was evaluated by measuring the polarization absorption spectroscopy. When the degree of the photoreaction was around 10 mol%, the reorientation direction was parallel to the polarization of LPUV light for both polymer films. On the other hand, when the degree of the photoreaction was low, out-of-plane orientation was observed for the polymer with the longer end group.
