摘要
设计并合成了一类新型末端氰基取代含氟二苯乙炔类液晶。 通过偏光显微镜和DSC对其相态进行了研究, 此类化合物仅呈现一个宽的向列相。 讨论了体积效应和极性因素对液晶稳定性及相变温度范围的影响。
Two series of tolan-type liquid crystals containing terminal cyano group were synthesized. Their phase transition temperatures were also measured by texture observation with a polarizing microscope and confirmed by DSC.All compounds only exhibit a nematic phase. Their mesomorphic properties and fluoro-substituents effect were studied in detail.
