A series of <I>N</I>,<I>N</I>′-dialkanoyl-2,4-bis(alkanoyloxy)-1,3-benzenediamines has been synthesized. The high temperature phases appearing in the heptanoyl to hexadecanoyl derivatives are viscous and are transformed into isotropic liquids with enthalpy changes of 20 kJ mol<SUP>−1</SUP> or less. Their X-ray diffraction patterns are characteristic of the hexagonal disordered columnar phase. The second moment of the broad-line proton NMR spectrum measured in the mesophase region is 0.8 to 0.9 G<SUP>2</SUP> in the case of the octanoyl derivative and 0.04 G<SUP>2</SUP> in the case of the tetradecanoyl derivative, indicating the rather large difference in the motional behavior between these half-disk-shaped molecules.
