    2-(p-取代苯基)-5-烷基-1,3-氧杂环己烷是一种新型液晶化合物,通过相应的醛和2-烷基-3-巯基-1-丙醇的缩醛化反应合成。将这些 1,3-氧杂噻吩化合物的介晶行为与相应的 1,3-二噻烷和 1,3-二氧杂环己烷的介晶行为进行了比较。一些 2-(对-氰基苯基)-5-烷基-1,3-氧杂环己烷在室温下表现出单向向列液晶相,而 2-(对-烷氧基苯基)-5-烷基-1,3-氧杂杂环杂芳烃几乎不呈现液晶相。这些介晶特征似乎源于 1,3-氧杂环庚烷环处的分子宽度和弯曲。

    日期:——
    A new approach to the synthesis of azulene liquid crystals is described based on Hafner’s procedure involving reaction of a pyridinium salt with a cyclopentadienide. The preparation of a variety of liquid crystalline materials using this method is described. Variants are reported with single substituents on the azulene ring in the 6-position and doubly substituted in the 2, 6- positions. The effect of the azulene ring as a core or dipolar terminal structural element is explored. 6-(5-Alkyl-1,3-dioxan-2-yl)azulenes are shown to exhibit smectic A phases and 2-cyclohexyl-6-(5-tridecyl-1,3-dioxan-2-yl)azulene show smectic A and B phases. Phase characterisation of the materials is recorded together with X-ray measurements on the smectic A phase of one representative compound. Results of dichroism studies on the azulene mesogens are also briefly reviewed.

  • The synthesis and electro-optic properties of liquid crystalline 2-(2,3-difluorobiphenyl-4′-yl)-1,3-dioxanes

    Fifty-six novel alkyl and/or alkoxy disubstituted 2-(2,3-difluorobiphenyl-4′-yl)-1,3-dioxanes (DFBPD) were prepared. Smectic C and nematic mesophases were exhibited by most of the alkyl-alkoxy homologues. Conversely, most of the dialkyl compounds exhibited smectic C, smectic A and nematic phases. The birefringence (Δn), dielectric anisotropy (Δε), spontaneous polarisation and response times of two ferroelectric mixtures formulated from the dioxanyl systems were determined. The birefringence results were compared with eight other groups of mixtures where the materials were based on different core systems. The overall electro-optic properties of the DFBPDs were found to be comparable to the best of the eight most commonly used materials in ferroelectric display devices.
    制备了 56 种新型烷基和/或烷氧基二取代的 2-(2,3-二氟联苯-4´-基)-1,3-二氧六环 (DFBPD)。大多数烷基-烷氧基同系物展现出近晶 C 和向列相中間相。相反,多数二烷基化合物展现出近晶 C、近晶 A 和向列相。测定了两个由二氧六环体系构成的铁电混合物的双折射 (Δn)、介电各向异性 (Δε)、自发极化和响应时间。双折射结果与基于不同核心体系的 8 组混合物进行了比较。发现 DFBPD 的整体电光性质与最常用的 8 种铁电显示器材料相当。
