  摘要：

  This paper reports on synthesis and investigation of columnar mesophases of the new members of the homologous series of nitro and amino derivatives of hexaalkoxytriphenylenes, whose mesomorphism was predicted earlier. The forecast is in good agreement with the experimental data. The effect of the introduction of the donor and acceptor groups into the central fragment of triphenylene on the phase transition temperature, texture, and range of existence of columnar mesophases is examined. The predicting ability of the molecular parameters suggested previously for the series under analysis is discussed. It is found that introduction of a nitro group, which is a strong electron acceptor, into the central fragment of triphenylene lowers the melting temperature of the compound versus its analog and does not promote columnar mesomorphism in the lower nonmesomorphous homologs. At the same time, this slightly expands the range of existence of the mesophase in higher homologs.

  摘要：

  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。

• Synthesis of Triphenylene and Dibenzopyrene Derivatives: Vanadium Oxytrichloride a Novel Reagent

  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.

• Triphenylene Columnar Liquid Crystals: Excited States and Energy Transfer

  The present paper deals with the photophysical properties of columnar Liquid crystals formed by hexakis-(alkyloxy)triphenylenes. Absorption and fluorescence spectra of solutions are analyzed on the basis of quantum chemical calculations performed by the CS-INDO-CI (conformations spectra-intermediate neglect of differential overlap-configuration interaction) method: the absorption maximum is due to the S-0-->S-4 transition while fluorescence originates from the weak S-0-->S-1 transition. In columnar aggregates, the former transition corresponds to delocalized excited states while the latter corresponds to localized ones; calculation of intermolecular interactions shows that, at the temperature domain of the mesophases, all the molecules have the same excitation energy and, therefore, no spectral diffusion of the fluorescence is expected, in agreement with the time-resolved emission spectra. Excitation transfer is investigated by studying the fluorescence decays of mesophases doped with energy traps. Their analysis is made by means of Monte Carlo simulations considering both intracolumnar and intercolumnar jumps and using four different models for the distance dependence of the hopping probability. The best description is obtained with a model based on the extended dipole approximation and taking into account molecular orientation.
