  Positional and Charged Effects of Heterocyclic N Atoms on Mesogenic Properties of Stilbazoles and Analogous N-Oxides

  摘要：

  The synthesis and the phase behavior of stilbazoles and corresponding N-oxides containing different positions of heterocyclic N atoms, i.e. trans-2'-, 3'-, 4'- stilbazoles and their N-oxides, are reported. Their phase transition temperatures and the mesogenic behavior were investigated through the DSC, polarizing optical microscope and X-ray diffraction (XRD) measurements. Increasing dipole moments by oxidation of stilbazoles to analogous N-oxides induces the S-A phase with an interdigitated bilayer packing. Both 2'-stilbazoles and analogous N-oxides do not possess mesogenic phases, which may be due that pi electron polarizabilities an reduced by the molecular twist originated from dipoles along the ortho-direction. Besides, the positonal effects of the N-oxides on mesogenic properties are more distinct than those of analogous stilbazoles, and new mesogenic phases have been generated by tuning the position of the N-oxide function in the charged liquid crystals. Consequently, unique mesogenic properties may he introduced through adjusting the dipolar direction and strength of the heterocyclic atoms in the molecules.

  具有低聚硅氧烷基的新的非手性苯乙炔单体，最适合于螺旋方向选择性聚合和获得良好的光学拆分膜材料

  摘要：

  为了开发更适合于螺旋正义选择性聚合（HSSP）的新型苯基乙炔单体，我们先前曾报道过，并且为了提高HSSP的效率和所得聚合物的膜性能，具有柔性低聚硅氧烷基（S n BDHPA）的新型苯基乙炔与通过使用手性催化体系合成和聚合了其他三个相关的单体系列，并研究了从所得手性聚合物中渗透膜的对映选择性。小号Ñ BDHPA是最适合HSSP和CD吸收（g ^聚值）（S ÑBDHPA）比相应的具有刚性烷基的聚合物更坚固，更稳定。可以通过溶剂浇铸法将聚合物制备成柔性的自支撑膜。另外，多（S n）之一的渗透的对映选择性BDHPA）膜比具有烷基的聚（苯乙炔）膜高得多。这是因为具有低硅氧烷基团的聚合物具有高规则性的结构，即膜的单手性等大分子的化学结构和膜中的柱状内容物等高阶结构，并且膜具有挠性并且几乎没有缺陷。这些优良的作为光学分辨率膜材料的特性是由低聚硅氧烷链的柔韧性，疏水性和膨松性引起的。发现具有三硅氧烷基的S

• Synthesis of Oligo(ethylene glycol) toward 44-mer
  作者：Saleh A. Ahmed、Mutsuo Tanaka

  DOI：10.1021/jo0617464

  日期：2006.12.1

  A synthetic method for oligo(ethylene glycol) toward 44-mer (FW = 1956.35) is described. Reiteration of Williamson's ether synthesis and hydrogenation to remove protecting benzyl group affords desired oligo(ethylene glycol) toward 44-mer in moderate yields. The advantages in this method are use of commercially easily available materials as starting materials and procedures avoiding difficulty in purification

A high density of the antenna chromophores was achieved without self‐quenching and excimer formation, thus affording extremely efficient energy transfer.

  The merger of ionic liquid and liquid crystal fields, obtained by using the imidazolium ring as a common element, has allowed us to tailor a new set of materials which associate specific functionalities. These functionalities are consequences of the original properties of the component, ionic liquids, liquid crystals and their association in a single compound. The study of this interesting association led us to elaborate environment-flexible cationic architectures from which mesomorphic properties emerge. Moreover, we have also explored the influence of different anions on the mesomorphic properties.
