说明

4'-辛基-4-联苯腈 (8CB) 是一种低摩尔质量液晶 (LC),根据温度条件显示不同的液晶相。 在常温条件下,8CB 仅作为块状近晶 A 相存在。 LC 对温度、剪切力、电场(或磁场)以及与其接触的固体表面结构的微小变化有反应。
8CB可用于制备不对称酞菁锌(aZnPc)-官能光固化共聚物。
LC 的单层薄膜沉积在高度有序的热解石墨上,这些自组装薄膜显示出多种结构形式。

一般描述

4′-octyl-4- biphenylcarbonitrile (8CB) is a low molar mass liquid crystal (LCs), which shows different liquid crystalline phases depending on temperature conditions. Under normal temperature conditions 8CB exists only as bulk smectic-A phase. LCs are responsive to minor changes in temperature, shear, electric (or magnetic) fields, and the structure of solid surfaces with which they are in contact.
 

应用

8CB may be used in the preparation of asymmetrical zinc phthalocyanine (aZnPc)-functional photocurable copolymer.
Monolayer films of the LCs deposited onto highly ordered pyrolytic graphite, these self-assembled films display a wide variety of structural forms.
