• Effects of isocyanide substituents on the mesogenic properties of halogeno(isocyanide)gold complexes: calamitic and discotic liquid crystals
  作者：Silverio Coco、Pablo Espinet、José M. Martín-Alvarez、Anne-Marie Levelut

  DOI：10.1039/a604258i

  日期：——

  The liquid crystal behaviour of linear [AuX(CNC 6 H 4 OC n H 2n +1 )] (X=halogen) complexes is tuned by systematically changing the structure of the isocyanide ligand. The changes studied are lateral fluorination at the 2- and 3-positions of the phenyl ring and modification of the rod-like structure of the complexes by addition of two alkoxy chains at themeta positions. None of the free isocyanides used here are liquid crystals, but all the gold complexes prepared display mesomorphic properties, except iodo(2-fluoro-4-butoxyphenyl isocyanide)gold(i). The (2- and (3-fluorophenyl isocyanide)gold(i) complexes show smectic A mesophases, except the 2-fluoro derivative with n=6, which shows a nematic phase, while the (3,4,5-trialkoxyphenyl isocyanide)gold compounds display columnar hexagonal phases at room temperature.

  通过系统地改变异氰酸配体的结构，调整了线性 [AuX(CNC 6 H 4 OC n H 2n +1 )] （X=卤素）配合物的液晶行为。所研究的变化是在苯基环的 2 位和 3 位进行横向氟化，以及通过在它们的eta 位置添加两条烷氧基链来改变配合物的杆状结构。这里使用的游离异氰酸酯都不是液晶，但除了碘（2-氟-4-丁氧基苯基异氰酸酯）金(i)之外，制备的所有金络合物都显示出介形特性。除了 n=6 的 2-氟衍生物显示出向列相外，（2-和（3-氟苯基异氰酸酯）金（i）复合物显示出 Smectic A 介相，而（3,4,5-三烷氧基苯基异氰酸酯）金化合物在室温下显示出柱状六方相。

• A New Class of Discotic Mesogens Derived from Tris(<i>N</i>-salicylideneaniline)s Existing in <i>C</i>₃<i>_h</i> and <i>C</i><i>_s</i> Keto-Enamine Forms

  Two series of a unique class of columnar liquid crystals derived from tris(N-salicylideneaniline)s [TSANs] in which the proton and the electron interact with each other through the H-bonding environment are reported. The synthesis is carried out by condensing 1,3,5-triformylphloroglucinol with the respective dialkoxyanilines or trialkoxyanilines. H-1 NMR and H-1-H-1 COSY NMR studies revealed their existence as an inseparable mixture of two keto-enamine tautomeric forms with C-3h and C-s rotational symmetries instead of the expected enol-imine form. The influence of the number of peripheral alkoxy tails on the columnar mesomorphic behavior is investigated by using polarizing optical microscopy, differential scanning calorimetry, and X-ray scattering. The fluid/glassy columnar states probed for a number of representative compounds confirmed the D-6h (hexagonal) or D-2h (rectangular) symmetry of the columns. The electronic absorption and emission characteristics of these compounds have been studied in both mesomorphic and solution states. Of special interest, the photoluminescence spectra of solution and fluid/ glassy two-dimensional structure evidently disclose the promising light generating capability of these new discotics systems.
• Discotic Liquid Crystalline Hydrazone Compounds:  Synthesis and Mesomorphic Properties

  1,3,5-Trisacetoacetamidobenzene with three 1,3-diketo groups was synthesized by the reaction of 1,3,5- triaminobenzene with diketene. Discotic hydrazone compounds were prepared by the diazo coupling reaction between 1,3,5- trisacetoacetamidobenzene and diazonium salts of 4-alkyloxyphenylamines. The compounds existed in hydrazone forms exclusively, being stabilized by the intramolecular hydrogen bonds, and showed discotic nematic or columnar hexagonal mesophases.
