反式-1,4-二芳基环己烷类液晶的合成及性能研究

Synthesis and Properties of trans-1,4-Diphenylcyclohexane Compounds

合成了一系列反式 -1 ,4 -二芳基环己烷类液晶化合物 ,总收率 1 1 .0 %～ 2 7.5 % ,较文献收率有显著提高 ;并用 IR和 1H NMR进行了结构鉴定。通过配方研究 ,发现该系列化合物具有低阈值的特性 。

A series of trans-1,4-diphenylcyclohexane compounds have been synthesized by a new routine with higher yield(11.0%～27.5%) than literature reported. All of these compounds are identified by IR and 1H NMR. Mixture formulations show that the compounds have lower threshold voltage and saturation voltages, indicating a wide prospect in liquid crystal display.
