A series of novel liquid crystalline octakis(alkylthio)-substituted phthalocyanines

Liquid crystalline phthalocyanines (Pcʹs) are promising materials for opto-electronic applications (e.g. solar cells, electrophotography) due to their high absorption coefficients in the long wavelength region of the optical spectrum and high charge carrier mobilities in the columnar mesophase. We report here the synthesis and properties, in particular the thermotropic phase behaviour, of a series of new octakis(alkylthio)-substituted pcʹs.
