Abstract
An extended-core liquid crystal (LC) based on the 3,3'-di(acylamino)-2 ,2'-bipyridine unit is investigated with respect to its behavior in al kane solvents. It is demonstrated that the lyotropic mesomorphism obse rved in dodecane can be tuned by varying the concentration of the samp le, and the columns can be switched in an electric field. The Figure s hows the structure of the columnar nematic phase present in dodecane c ontaining 15.7 wt.-% LC.
