  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.

  摘要：

  离子液体和液晶领域的合并，通过使用咪唑环作为共同元素，使我们能够定制一组新材料，这些材料具有特定的功能。这些功能是组分的原始性质——离子液体、液晶及它们在单一化合物中的结合——的结果。对这种有趣的结合的研究使我们能够从中制定出环境灵活的阳离子结构，从中产生出介向性质。此外，我们还探讨了不同阴离子对介向性质的影响。

  Twenty-one n-alkoxy substituted phenylenevinylene oligomers were synthesized, varying in size, number and position of the OR groups. IR,MS and solubility data are presented. NMR measurements provided the molecular structure as well as information about conformations and molecular dynamics. UV and of cyclic voltammetric data give correlations of chemical structure (number and position of OR substituents) with separate HOMO and LUMO energies. (C) 1997 Elsevier Science Ltd.

• Synthesis and thermotropic behaviour of bis(imidazolium) salts bearing long-chain alkyl-substituents and of the corresponding dinuclear gold carbene complexes

  New propylene bridged bis(imidazolium) salts bearing at the wingtip positions a benzyl group functionalised with one or two long alkyl chains, as well as the corresponding dinuclear N-heterocyclic dicarbene gold(I) complexes of general formula [Au-2(RIme-(CH2)(3)-ImR)(2)](X)(2) (X = Br, PF6, BF4) have been synthesised and thermally characterised. All the compounds are stable up to 200 degrees C and the bis(imidazolium) salts [H-2(RIm-(CH2)(3)-ImR)](X)(2) (X = Br, PF6) behave as thermotropic liquid crystals in the temperature range 100-200 degrees C. By contrast, only the gold(I) diNHC complexes with eight aliphatic chains present mesomorphism, whereas those with four chains show numerous crystalline phases with structural disorder and presumably modified AueAu distances, as indicated by solid state emission properties.
