The first group of fully characterised mesogenic (E,E)-1,4-diarylbuta-1,3-dienes, substituted in the para-position of one aryl ring by an alkoxy-group and in the para-position of the other aryl group by a cyano- or halogeno-group has been prepared by a Wadsworth–Emmons procedure; their physical properties of high birefringence and low viscosity in combination make them particularly suitable for use in liquid crystal display devices when mixed with known liquid crystalline materials.
第一组完全表征的介晶(E,E)-1,4-二芳基丁-1,3-二烯已通过Wadsworth–Emmons反应合成,其一个芳环的对位被烷氧基取代,另一个芳环的对位则被氰基或卤素取代。这些化合物的高双折射率和低粘度的物理特性组合,使其在与已知液晶材料混合时,特别适合用于液晶显示设备中。
