Abstract

Preliminary results of investigations on hexa-amides of benzenehexamine demonstrate that these disc-shaped compounds - as such already known since 1937 - exhibit very interesting lyotropic liquid crystalline properties in various lipophilic solvents. At lower concentrations (e.g. about 20 wt.%) a nematic phase with an extraordinary wide range of stability (at least 65 °C!) has been found, whereas at higher concentrations a second mesophase exists with hexagonal structure.
