STAR-LIKE DISCOTIC LIQUID-CRYSTALS

The game of molecular engineering of liquid crystalline systems via a combination of molecular architecture and functionalization of mesogen s has opened interesting perspectives in the field of liquid crystals. Here we report on the synthesis and characterization of star-like hep tameric triphenylenes. The discotic subunits in these molecules have b een arranged in a hexagonal fashion around a central discotic core, th us leading to a new type of molecular arrangement for discotic liquid crystals. These oligomers do not crystallize and combine a well-define d structure with a discotic polymer-like processing.
