  Synthesis and Characterization of Ferroelectric and Antiferroelectric Liquid Crystals Derived from (2S)-2-(6-Hydroxy-2-Naphthyl) Propionic Acid

  摘要：

  A new series of chiral materials, hexy](2s)-2-(6-(-4-(4'-alkoxyphenyl)benz propionates (HmPBNP; m = 6-18) had been prepared and their liquid crystalline properties were investigated as a function of alkyl chain length. These chiral materials exhibited novel ferroelectric S-c* and antiferroelectric Sc-A* phases and a propensity to the formation of the Sc-A* phase was found at longer alkyl chain lengths (m = 10, 12-18). An odd-even effect of the threshold voltage as a function of alkyl chain length for compounds HmPBNP (m = 12-16) possessing antiferroelectricity was observed. Spontaneous polarization and trans verse dipole moment were also measured and are discussed in terms of the elongated alkyl chain length.

  A new liquid crystal phase, denoted modulated helical nanofilament (HNF(mod)), is formed from a very simple class of biphenyl carboxylates lacking the benzylidene aniline moieties typically found in HNF mesogens. The HNF(mod) phase represents a novel kind of nanoparticle possessing stacked aromatic rings, with potential applications in organic electronics.

  一种新的液晶相，称为调制螺旋纳米丝（HNF （mod）），是由一类非常简单的联苯羧酸盐形成的，该联苯羧酸盐缺乏通常在HNF介晶材料中发现的亚苄基苯胺部分。HNF （mod）相代表一种具有堆积的芳环的新型纳米粒子，在有机电子领域具有潜在的应用。
