    摘要:
    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。

  • The synthesis and electro-optic properties of liquid crystalline 2-(2,3-difluorobiphenyl-4′-yl)-1,3-dioxanes
    作者:Chu Chuan Dong、Peter Styring、John W. Goodby、Lawrence K. M. Chan
    DOI:10.1039/a902351h
    日期:——
    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。
  • Mesogenic, optical, and dielectric properties of 5-substituted 2-[12-(4-pentyloxyphenyl)-p-carboran-1-yl] [1,3]dioxanes

    DOI:10.1039/b608012j
    日期:——
    Two homologous series of carborane-containing dioxanes 1[n] and 2[n] (n = 1–10) were prepared and their mesogenic properties investigated. All compounds exhibit nematic behavior and three members of series 2[n] show an E phase. Numerical analysis of the clearing temperatures gave a limiting value TNI(∞) of 89 °C for series 2[n] and indicated conformational flexibility of the dioxane ring. Investigations of three-ring derivative 1[4] gave Δn = 0.17, S = 0.53, and Δε = +0.4 ± 0.1 at 85 °C. Extrapolation of dielectric data for dilute solutions of 1[4] in 6-CHBT gave Δε = +0.4 ± 0.25 at 24 °C. Modelling of dielectric results with the Maier–Meier equation demonstrated that conformers with a higher β angle are preferred, which is consistent with conformational selection for the most elongated conformers.
    准备了两个含有碳硼烷的二噁烷同系物系列1[n]和2[n](n = 1–10),并对它们的介晶性质进行了研究。所有化合物均表现出向列行为,而系列2[n]中的三个成员显示出E相。清晰温度的数值分析给出了系列2[n]的极限值TNI(∞)为89°C,并表明二噁烷环的构象灵活性。对三环衍生物1[4]的研究得到了Δn = 0.17,S = 0.53,以及在85°C时Δε = +0.4 ± 0.1。对1[4]在6-CHBT稀溶液中的介电数据进行外推时,在24°C得到了Δε = +0.4 ± 0.25。利用Maier–Meier方程对介电结果的建模表明,具有更高β角的构象更为偏好,这与对于最细长构象的构象选择一致。

    日期:1984.7
    2-(p-Substituted phenyl)-5-alkyl-1,3-dithianes, new liquid crystals, were synthesized by the thioacetalization of the corresponding aldehydes and dithiols. These compounds have characteristic supercooling states, exhibit monotropic liquid crystal phases even in the case of long terminal alkyl substituents. The mesomorphic characteristics of these compounds were different from those of the corresponding
    2-(p-取代苯基)-5-烷基-1,3-二噻烷是一种新型液晶,通过相应的醛和二硫醇的硫缩醛化反应合成。这些化合物具有特征性的过冷状态,即使在长末端烷基取代基的情况下也表现出单向性液晶相。这些化合物的介晶特性与相应的1,3-二恶烷不同,这一定是由于硫和氧原子体积不同而导致分子宽度不同。
