一般描述
4′-辛基-4-联苯腈(8CB)是一种低摩尔质量液晶(LC)，其液晶相随温度条件的变化而不同。在常温条件下，8CB仅以体近晶A相存在。LC可以对温度、剪切、电场（或磁场）以及与之接触的固体表面结构的细微变化做出反应。
应用
LC 的单层膜沉积在高度有序的热解石墨上，这些自组装膜表现出各种各样的结构形式。

Numerous applications of liquid crystals rely on control of molecular orientation at an interface. However, little is known about the precise molecular structure of such interfaces. In this work, synchrotron X-ray reflectivity measurements, accompanied by large-scale atomistic molecular dynamics simulations
