  具有苯硫基苯甲酸酯侧基的液晶聚合物的合成和光致重取向

  摘要：

  合成具有4-甲氧基苯基硫代苯甲酸酯侧基的液晶聚（甲基）丙烯酸酯（LCP），以获得在可见光区域透明的光致分子取向结构。使用线性偏振（LP）313 nm光研究了薄膜的轴选择性光反应和光诱导的重新取向行为。侧基的轴选择性光反应在所有LCP薄膜中均产生了光学各向异性，但振幅取决于亚烷基间隔基长度和聚合物主链的类型。光辐照的膜在可见光区域是透明的，因为光反应的产物表现出较少的颜色。当介晶基团通过六亚甲基间隔基连接到聚合物主链时，S）为0.62，双折射（Δn）约为0.17。相反，当LCP包含长的亚烷基间隔基时，面外重定向占主导。

  悬垂三唑环辅助含液晶元的侧链液晶聚甲基丙烯酸甲酯：合成与表征

  摘要：

  通过自由基聚合技术合成了两套点击化学辅助的含烷氧基甲基-1H- [1,2,3]-三唑-1-基的侧链液晶聚甲基丙烯酸甲酯。液晶元通过各种间隔单元连接到主链。通过FT-IR，1 H和13表征单体和聚合物C-NMR光谱技术。通过热重分析证实了聚合物的热稳定性。通过差示扫描量热法和偏振光学显微镜分析了聚合物的介晶性质和相变温度。研究了相对于末端三唑环上极性烷氧基的插入以及主链与介晶之间的间隔基长度的聚合物的相变温度和介晶性质。在偏振光学显微镜下，聚合物表现出颗粒状纹理。介晶和主链之间的间隔长度改变了聚合物的相变温度。 通过自由基聚合技术合成了两套点击化学辅助的含烷氧基甲基-1H- [1,2,3]-三唑-1-基的侧链液晶聚甲基丙烯酸甲酯。
