  异氰基铑(I)配合物的超分子组装：铑(I)…铑(I)相互作用、疏水-疏水相互作用和主客体化学的相互作用

  摘要：

  已发现一系列具有不同链长烷基取代基的四（异氰基）铑（I）配合物在改变浓度、温度和溶剂组成时表现出强烈的溶液状态聚集趋势。已经进行了与温度和溶剂相关的 UV-vis 吸收研究，并使用聚集模型分析了数据以阐明生长机制。发现聚集涉及广泛的 Rh(I)...Rh(I) 相互作用，这些相互作用在疏水-疏水相互作用的协同辅助下产生彩虹般的溶液聚集体颜色。值得注意的是，三个长烷基取代基的存在对于观察到的聚合协同性至关重要。在己烷-二氯甲烷溶剂混合物中观察到纳米板和纳米囊泡形式的分子组装，这是由于基于复合物的烷基链长度的不同形成机制引起的。Benzo-15-crown-5 部分已被纳入选择性钾离子结合以诱导二聚体形成和剧烈的颜色变化，使该系统成为潜在的比色和发光阳离子传感器以及离子控制超分子组装的构建块。

  A New Class of Discotic Mesogens Derived from Tris(N-salicylideneaniline)s Existing in C_3h and C_s Keto-Enamine Forms

  摘要：

  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.

• Synthesis of Triphenylene and Dibenzopyrene Derivatives: Vanadium Oxytrichloride a Novel Reagent
  作者：Sandeep Kumar、Sanjay K. Varshney

  DOI：10.1055/s-2001-10821

  日期：——

  This paper presents an efficient synthetic procedure for the preparation of various triphenylene and dibenzopyrene derivatives using VOCl3 as a novel reagent. Symmetrically substituted hexaalkoxytriphenylenes are obtained from o-dialkoxybenzenes by oxidative trimerization with VOCl3 in high yields. The oxidative coupling of a 3,3′,4,4′-tetraalkoxybiphenyl and 1,2-dialkoxybenzenes or 1,2,3-trialkoxybenzenes affords unsymmetrically substituted derivatives of triphenylene. The reagent oxidizes 3,3′,4,4′-tetraalkoxybiphenyl efficiently to 2,5,6,9,12,13-hexaalkoxydibenzo[fg,op]naphthacene-1,8-quinone and its 1,10-quinone isomer. Both the quinones can be converted to liquid crystalline derivatives using well-established chemistry. Effects of solvent, reagent concentration, acid catalyst and temperature have been studied.

  本文介绍了一种使用 VOCl3 作为新型试剂制备各种三亚苯和二苯并芘衍生物的高效合成方法。用 VOCl3 氧化三聚法从邻二烷氧基苯得到了对称取代的六烷氧基三亚苯，产率很高。将 3,3′,4,4′-四烷氧基联苯与 1,2-二烷氧基苯或 1,2,3-三烷氧基苯氧化偶联，可得到不对称取代的三亚苯衍生物。该试剂可将 3,3′,4,4′-四烷氧基联苯高效氧化为 2,5,6,9,12,13-六烷氧基二苯并[fg,op]萘-1,8-醌及其 1,10-醌 异构体。这两种醌类化合物都可以利用成熟的化学方法转化为液晶衍生物。研究了溶剂、试剂浓度、酸催化剂和温度的影响。
• Novel heptasubstituted triphenylene discotic liquid crystals

  The synthesis and characterisation of several hepta-substituted triphenylene derivatives are reported. These unsymmetrically substituted triphenylene derivatives are of three varieties, i) with seven identical peripheral alkoxy chains, ii) two or three out of the seven alkoxy chains have different chain lengths and, iii) the mode of the attachment of two of the peripheral chains is different, i.e.via ester linkages. The heptaalkoxytriphenylenes were prepared by two different routes, either starting from monohydroxypentakis(alkoxy)triphenylenes or via a biphenyl route using either MoCl5 or FeCl3 as oxidants. Unsymmetrical substitution has a large effect on the thermal behaviour but the type of mesophase formed does not change. Photomicroscopic pictures of all the 21 liquid crystalline compounds reported here show classical textures of an ordered hexagonal columnar (Colh) phase. X-Ray diffraction studies of five representative compounds confirmed the above conclusions. Mixed ether–ester derivatives have smaller core–core separations and higher correlation length, therefore, are better candidates for charge transport studies.

  报告了几种庚代三亚苯衍生物的合成和特性。这些不对称取代的三亚苯基衍生物有三种类型：①具有七条相同的外围烷氧基链；②七条烷氧基链中的两条或三条具有不同的链长；③两条外围链的连接方式不同，即通过酯连接。七烷氧基三亚苯的制备有两种不同的路线，一种是从单羟基五（烷氧基）三亚苯开始，另一种是以 MoCl5 或 FeCl3 作为氧化剂，通过联苯路线制备。不对称取代对热性能有很大影响，但形成的介相类型并没有改变。本文报告的所有 21 种液晶化合物的光电显微图片都显示了有序六方柱状（Colh）相的经典纹理。对五种代表性化合物进行的 X 射线衍射研究证实了上述结论。 混合醚酯衍生物的核心-核心分离度较小，相关长度较高，因此更适于电荷传输研究。
