  Liquid Crystals Derived from Semifluorinated Alkoxybenzoyl Hydrazines

  摘要：

  A variety of liquid crystals with semifluorinated tails including 4-alkoxybenzoic acids (1d-h), 4-alkoxybenzoyl hydrazines (2d-h), and N,N'-bis(4-alkoxybenzoyl) hydrazines (3d-m) have been synthesized, and their properties are compared with their perhydrogenated analogs. Semifluorination in compounds 1d-h suppressed nematic phases, and semifluorinated compounds 2d-h exhibit mesogenic behavior where none is found in their perhydrogenated counterparts. Compounds 3a-c with perhydrogenated chains display Cub and SmC phases. Introduction of one semifluorinated chain, 3d-h suppresses the Cub phase but induces a SmA phase, with lower melting but higher clearing temperatures compared to compounds with two semifluorinated chains, 3i-m. The mesogenic properties of some selected binary mixtures of these compounds 3a-d and some lateral fluoro substituted N,N'-bis (4-alkoxybenzoyl) hydrazines 7-9 are also discussed.

  Abstract We present the synthesis and liquid crystalline properties of four sets of diphenyl-1,3,4-oxadiazole based compounds (Sets 1–4). The influence of side chain and lateral fluorinations is discussed. In this study, side chain fluorination (Sets 2 and 3) induces liquid crystalline properties, while lateral fluorination (Set 4) has not induced mesogenic properties. Compounds with either one or

  摘要 我们介绍了四组基于二苯基-1,3,4-恶二唑的化合物（第 1-4 组）的合成和液晶性质。讨论了侧链和侧向氟化的影响。在本研究中，侧链氟化（第 2 组和第 3 组）诱导液晶性质，而侧链氟化（第 4 组）没有诱导介晶性质。具有一个或两个半氟化侧链的化合物是近晶介晶（SmC 和/或 SmA）。二苯基-1,3,4-恶二唑、联苯基-1,3,4-恶二唑、二苯基-1,3,4-噻二唑和联苯基-1,2,4-恶二唑核之间的比较，我们有以前报道过，讨论过。
