说明

4-己基联苯腈属于低分子量液晶 (LCs) 类。 LC的光学特性可以通过热控制。 它可以通过热转换从不透明状态变为透明状态。 这种效应是由于 LC 的双折射特性而出现的。 低分子量 LC 表现出对温度的高度依赖性和强烈的温度依赖性，并且在聚合物基质中具有更高的溶解度。 它还表现出很强的偶极矩。

一般描述

4′-Hexyl-4-biphenylcarbonitrile belongs to the class of low molecular weight liquid crystals (LCs). Optical properties of LCs can be controlled thermally. It can be rendered opaque to transparent state by thermal switching. This effect appears on account of birefringence feature of LCs. Low molecular weight LCs show high, and strongly dependence on temperature as well as possesses higher solubility in polymer matrices. It also exhibits a strong dipole moment.
 

应用

  • Used in thermoresponsive meso/nanostructured PS-b-PEO block copolymer-dispersed liquid crystal.
  • 4′-hexyl-4-biphenylcarbonitrile, 4′-octyloxy-4-biphenylcarbonitrile and their composite liquid crystals were studied for dielectric properties.
Proposed applications are in the field of
  • thermo- and electro optical devices (e.g. optical shutters, smart windows, optical sensors,memories and flexible display devices),
  • n phase array optics (e.g. as switchable birefringent phase shifters).
