  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.

  Reaction of PtCl2 in the melt of a ligand, L, leads in most cases to the complex [PtCl2L2] in good yield, with short reaction time. In all cases either pure cis or pure trans isomer is produced, depending on the nature of L.

  Introduction of long-chain alkoxy substituents into molecules of styrylpyridines as potential ligands for photosensitive metal complexes endows them with liquid crystalline properties over a wide temperature range. trans-cis Photoisomerization of 4-alkoxystyrylpyridines in solution was revealed by NMR and electronic absorption spectroscopy, and the kinetics of transformations of their molecular forms after irradiation were estimated. Photoinduced trans -> cis isomerization of 4-alkoxystyrylpyridines is characterized by a higher rate, and intramolecular cyclization of their cis isomers after irradiation is slower, as compared to unsubstituted analog.

• Angular (cis-stilbazole) geometry in octahedral dimethyldihalidoplatinum(IV) complexes: potential as metallomesogens and X-ray structure of [PtMe2I2(NC5H4CHCHC6H4OC7H15)2]
  作者：Paul Beagley、Earl J Starr、John Bacsa、John R Moss、Alan T Hutton

  The synthesis and characterisation of a series of octahedral dimethyldihalidoplatinum(IV) complexes of 4-alkoxy-4'-stilbazoles with the general formula [PtMe2X2(NC5H4CH=CHC6H4OR)(2)] (X = I or Br, R = n-alkyl) is described. Some of the complexes show mesogenic behaviour. The structure of the complex with X = I and R = C7H15 has been determined by X-ray crystallography, revealing a cis coordination geometry with respect to both the methyl and the substituted 4-alkoxy-4'-stilbazole (n-OST) ligands.
