摘要

以烷基苯乙酮为原料通过一系列反应制备出新一类嘧啶液晶

对其性能进行了测试。比较了嘧啶环连接氰基时

两个氮原子不同朝向对液晶性质的影响。研究结果表明

这类液晶具有较大的光学各向异性和介电各向异性。

Abstract

A new class of pyrimidine liquid crystals was synthesized through a series of reaction with benzene acetophenone as the raw material

and their performances were tested. Effect of different directions of the two nitrogen atoms in the cyano-pyrimidine ring on the liquid crystals performances was researched. The results show that this kind of liquid crystals has large optical anisotropy and dielectric anisotropy.
