A novel dichiral azobenzene compound which shows two kinds of highly ordered liquid-crystalline phases was prepared. One of the mesophases was found, by miscibility studies, to be a chirality-induced three-dimensional (3D) liquid crystal phase. We, for the first time demonstrate the photoinducedphasetransition of the liquid-crystalline 3D structure.
制备了一种具有两种高度有序液晶相的新型二手性偶氮苯化合物。通过混溶性研究发现其中一个中间相是手性诱导的三维 (3D) 液晶相。我们首次展示了液晶 3D 结构的光致相变。
