Liquid crystalline octasubstituted lead(ii) phthalocyanines: Effects of alkoxy and alkylthio substituents on film alignment and electrical properties

Octasubstituted lead(ii) phthalocyanines containing alkylthio- and alkoxy- groups in peripheral positions have been synthesized and characterized using 1H and 13C NMR, UV-Vis, IR and mass spectroscopies as well as elemental analysis. The mesogenic properties of the octasubstituted lead(ii) phthalocyanines have been investigated by differential scanning calorimetry, polarizing optical microscopy, and X-ray diffraction. The sandwich structures ITO/PbPc/In were prepared to investigate the J(V) characteristics of thin films of these molecules. The dissimilar behavior of the films before and after heat-treatment is expected to result in changing the alignment inside the columnar stacking of the molecules in the films.

Control of the Discotic to Isotropic Transition in Alkoxy-Substituted Silicondihydroxo-Phthalocyanines by Axial Substituents

The synthesis of a homologous series of octaalkoxy-substituted silicondihydroxo-phthalocyanines is described.The mesomorphic properties of these new materials were studied by DSC, optical microscopy and X-ray investigations.Compounds with n >/= 4 (n is the number of carbon atoms in a single alkoxy side chain) show a discotic mesophase transition.A transition to the isotropic state is only observed when n >/= 8.X-ray diffraction patterns of the mesophases confirm that all compounds form a hexagonal columnar mesophase of the type Dhd.
