  Mesomorphic Dithiooxamide Complexes of Platinum(II)

  摘要：

  Complexation of non-mesomorphic dithiooxamide ligands to Pt(II) leads to square planar complexes which exhibit mesomorphic properties. The synthesis of these complexes was accomplished in three steps: the formation of bisamides, starting from conveniently substituted anilines, their conversion into dithiooxamides and the reaction of these sulfur derivatives with [PtCl2(dmso)(2)]. Four, eight and twelve-chained complexes were obtained and their behaviour as potentially mesomorphic material was studied. The eight-chained complexes 21 (n = 12-16) and the twelve-chained complexes 22 (n = 8,11,13) exhibit columnar mesophases which have been characterised by optical microscopy, X-ray scattering and related miscibility studies.

• An Unusual Stacking Transformation in Liquid-Crystalline Columnar Assemblies of Clicked Molecular Propellers with Tunable Light Emissions

  The columnar liquid‐crystalline (LC) and fluorescence properties of three‐dimensional molecular propellers based on tetraphenylethylene is reported. X‐ray scattering studies reveal an unusual transition from a rectangular (Colrec) to a hexagonal columnar (Colhex) phase. In contrast to second‐order intercolumnar transitions based on a common tilt mechanism, the transition is first order and involves

  4-dialkoxyphenyl tosylamino groups at the peripheral positions have been synthesized from 1,2-dicyano-4,5-bis[(3,4-dialkoxyphenyl-tosylamino)methyl]benzene in the presence of the corresponding anhydrous metal salt. Next to the metal ion center, the length of the alkyl chains in the dialkoxyphenyl moiety (n = 4, 5, 6, and 12) was varied. In total, sixteen soluble phthalocyanines have been characterized by elemental

• 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.
