    Photoalignment of liquid crystals using a covalently attached self-assembled ultrathin film fabricated from diazoresin and cinnamate polyelectrolyte
    摘要:
    重氮树脂(DR)和聚[4-磺酰基苯氧基(4-丙烯酰氧基)肉桂酸钠盐](PACSS)在水溶液中通过静电吸引作用制成了逐层薄膜。在 365 纳米紫外线的照射下,薄膜中重氮离子和磺酸根离子之间的离子键转化为共价键。同时还证实,在此过程中,PACSS 中肉桂酰基的乙烯基单元没有发生变化。含有光敏肉桂酰基的共价连接自组装超薄薄膜经线性偏振紫外光(LPUVL)照射后,可使液晶(LC)均匀排列并具有良好的稳定性。本研究利用偏振紫外可见光谱来研究共价膜的光化学过程。研究发现,与 LPUVL 的偏振方向平行的肉桂酰基在光反应中的消耗速度快于与偏振方向垂直的肉桂酰基。由此可以得出结论,选择性光反应诱导了薄膜的各向异性。实验结果表明,薄膜的光反应程度和二向色比率取决于吸附层的数量和照射时间。这些结果与平行液相池中的液相均匀排列行为相关。发现液相色谱分子的重新定向行为与共价膜厚度和辐照时间有关。
