合成了一系列具有荧光性质的手性棒状化合物。用核磁共振氢谱（1H NMR）、碳谱（13 C NMR）和二维异质多量子关联（HMQC）方法对所合成材料的化学结构进行了表征。此外，宾主型液晶（LC）设备，使用这些化合物和电场驱动的旋光开关的LC设备的基础上的螺旋-单轴取向的变化进行了演示。大的旋光度来自于有序的螺旋结构。（本文有补充材料。访问出版商的在线版《分散科学与技术杂志》，查看免费的补充文件。
A series of chiral rod-like compounds with fluorescence was synthesized. The chemical structures of the materials thus synthesized were confirmed with1H nuclear magnetic resonance spectroscopy (NMR),13C NMR, and two-dimensional heteronuclear multiple quantum correlation (HMQC) methods. Furthermore, guest-host type liquid crystal (LC) devices were prepared using these compounds and electric field driven optical rotation switching of the LC devices based on change in helix-uniaxial orientation was demonstrated. The large optical rotation is derived from the helical structure of the ordered cholesteric LC. (Supplemental materials are available for this article.
