The mesomorphic properties of dibenzotetraaza[14]annulene complexes an
d ligands bearing four alkoxy chains are described. They were investig
ated by microscopic observations, DSC experiments and X-Ray diffractio
n studies. All the compounds, even the short chains homologues, exhibi
t wide range hexagonal columnar phases.
