(S)-2-甲基丁氧基氟代联苯甲酸苯酯类液晶化合物的合成及其性能研究

SYNTHESIS AND PROPERTIES OF CHIRAL 4—CYANOPHENYL AND 4—ALKYPHENYL (+)—4′—((S)—2—METHYLBUTOXY) —4—BIPHENYL CARBOXYLATE LIQUID CRYSTALS

合成了１０个（Ｓ）—２—甲基丁氧基氟代联苯甲酸苯酯类液晶化合物，测试了它们的物理性能，并就其性能与结构之间的关系进行了探讨。这些液晶化合物已在ＴＮ和ＦＬＣ实用配方中得到了较好的应用。

title compounds useful in LC material were prepared and their liquid crystals properties were investigated The compounds with fluoro substituting group have lower melting point and phase-transition tempe rature, dielectric anisotropies The effect of cyano-group was also discussed These compounds have been used as excellent hosts in TN and FLC mixtures
