• Rewritable color recording media consisting of leuco dye and biphenyl developer with a long alkyl chain
  作者：Katsuyuki Naito

  DOI：10.1039/a801616j

  日期：——

  Media formulated using two compounds (a leuco dye and 4-alkoxyl-4′-hydroxybiphenyl) were colored in the amorphous state and colorless in the crystalline state. As the alkyl chain length of the biphenyl compound increased, the contrast ratio and thermal stability of the amorphous states increased. Additionally, the crystallization velocity increased for the media with a long alkyl chain. Leuco dyes with a high glass transition temperature also produced thermally stable amorphous states. The origin of the long alkyl chain effects is discussed.

  使用两种化合物（无色染料和 4-烷氧基-4'-羟基联苯）配制的介质在无定形状态下有色，在结晶状态下无色。随着联苯化合物烷基链长度的增加，非晶态的对比度和热稳定性增加。此外，具有长烷基链的介质的结晶速度增加。具有高玻璃化转变温度的无色染料也产生热稳定的无定形状态。讨论了长烷基链效应的起源。
• Molecular Mechanism of Anomalous Increase in the Helical Pitch of Cholesteric Liquid Crystals Induced by Achiral Dopants

  A dopant-induced anomalous increase in the helical pitch of dicholesteryl 10,12-docosadiynedioate 1 is explained by generation of smectic clusters in the cholesteric phase where the dopants act as promoters of smectic domains. The dopants, having a mesogenic core and the proper length of alkyl chains on both their molecular sides, such as 4,4'-dialkylazobenzenes, 4,4'-dialkylazoxybenzenes and 4,4'-dialkylbiphenyls, considerably increase the pitch. However, dopants having benzene or a binaphthyl structure in the molecular center, an alkyl chain at one side of the molecules and Z-isomers of azobenzene and azoxybenzene derivatives, slightly decrease the pitch by acting as impurities that decrease the transition temperature of the host. An X-ray diffraction study of the cholesterics revealed that the pitch increases with an increase in size and amount of the smectic domains induced by the appropriate dopants.
• New Liquid Crystal Materials with a Terminal Alkyl Sulfonic Acid Unit

  New liquid crystal materials with a terminal alkyl sulfonic acid group were synthesized. The mesomorphic behavior of these compounds was evaluated. These compounds generate the SmA phase, and in the SmA phase, the molecules seem to be able to transport protons. At the temperature of the smectic phase, the proton current increased sharply. The proton transport ability increases about 700 times by forming a smectic molecular order.
• Design and Synthesis of Novel Calamitic and Discotic Materials Based on the Photorefractive Carbazole Unit

  The incorporation of photorefractive molecular units, such as carbazole, into anisotropic materials (liquid crystals) may offer many advantages over conventional electrical poling of photorefractive polymers. Thus, a series of symmetric 3,6-disubstituted carbazole derivatives with well-known biphenyl and triphenylene liquid-crystalline moieties was synthesized and characterized. These modifications were achieved by the esterification of bishydroxy carbazole derivatives with monoalkylated biphenyl carboxylic acids and alkylation of bisacylated bromo- derivatives of carbazole with monohydroxy pentaalkoxy triphenylene. The pure compounds are not liquid-crystalline, even when doped with trinitrofluorenone (TNF), unlike triphenylene/carbazole materials that we reported previously. These compounds, although not liquid-crystalline, may be of interest in the field of photorefractivity.
