• The synthesis and mesomorphism of di-, tetra- and hexa-catenar liquid crystals based on 2,2′-bipyridine

  2,2′-Bipyridines are known to coordinate to a wide variety of metal centres. In this paper, liquid-crystalline two-chained (dicatenar), four-chained (tetracatenar) and six-chained (hexacatenar) bipyridines are synthesised and their mesomorphism is described. For the tetracatenar bipyridines, a full homologous series, from tetramethoxy to tetratetradecyloxy, was synthesised, and the phase diagram showed a classic progression from nematic and smectic C phases at short chain length, through a cubic phase to a columnar phase.

• Tailoring thermotropic cubic mesophases: amphiphilic polyhydroxy derivatives

  Novel amphiphilic polyhydroxy compounds [N-(3,4-dialkoxybenzoyl)-1-amino-1-deoxy-d-glucitols (glucamides), N-(3,4-dialkoxybenzoyl)-1-deoxy-1-methylamino-d-glucitols, N-(3,4,5-trialkoxybenzoyl)-1-deoxy-1-methylamino-d-glucitols (N-methylgucamides), 1-benzoylaminopropane-2,3-diols, 2-benzoylaminopropane-1,3-diols, 2-(3,4,5-tridodecyloxybenzoylamino)-2-(hydroxymethyl)propane-1,3-diol and (3,4,5-tridodecyloxybenzoyl)bis(2,3-dihydroxypropyl)amine] have been synthesized. Their thermotropic liquid crystalline phases were investigated by means of polarizing microscopy, differential scanning calorimetry and X-ray diffraction. Depending on the chain length, and the size of the hydrophilic polyhydroxy units, different mesophases have been found: smectic A phases (SA), inverted bicontinuous cubic phases (CubV2 , Ia3d), hexagonal columnar phases (ColH2) and micellar cubic mesophases (CubI2 , Pn3m or P43n). In strong analogy to lyotropic systems, the type of thermotropic mesophase depends on the ratio between the volume of the lipophilic moiety and the surface area of the hydrophilic moiety at the hydrophilic–lipophilic interface. The crossing from zero interface curvature (SA phase) to the finite negative curvature of the inverted cylindrical aggregates of the columnar mesophase takes place via bicontinuous cubic mesophases. The cylindrical aggregates of the columnar mesophase are stable over a rather broad range of variation of the structural parameter. At a certain degree of the size of the lipophilic moiety in respect to the surface area of the hydrophilic group, however, the transition from the hexagonal columnar to a micellar cubic mesophase takes place. On the basis of proton conductivity measurements and from packing considerations we propose that this cubic lattice is built up by eight closed micelles per unit cell which have a rod-like shape and represent small segments of extended columns. Therefrom we can propose a model for the transformations between these different thermotropic mesophases.

  The electronic properties of series of mononuclear ortho-platinated and -palladated metallomesogens were investigated by means of UV-vis absorption and fluorescence spectroscopy in solution, fluorescence spectroscopy in the solid state as well as time-resolved photo-emf measurements. The organoplatinum compounds show luminescence in solution and in the solid state as well as photoconductivity caused by Pt⋯Pt closed shell interactions in comparison to the non-luminescent and non-photoconductive organopalladium compounds. A significant influence of the substitution pattern regarding luminescence and photoconductivity of the materials (number, length and distribution of attached alkyl chains) was found for the organoplatinum phenylpyrimidine and phenylpyridine series 1 and 3.

  A series of materials based on the aroylhydrazinatonickel (II) complex is synthesized and characterized. The molecule in the materials consist of two 4-benzoyloxy-benzene groups and two benzene rings having two or three alkoxy chains containing 6, 8, 10, and 12 carbon atoms attached at the azomethine moiety. The synthesis, characterization by NMR and the phase sequence observed by DSC and polarized light microscopy are presented. Most of the compounds in the series display columnar phases in the temperature range between 100 degrees C and 200 degrees C. The phases observed and their temperature ranges are discussed in terms of the number and position of attached alkoxy chains.
