The mesomorphic properties of some dibenzotetraaza[14]annulene complex
es bearing six and eight alkoxy chains have been investigated by micro
scopic observations, DSC experiments and X-ray diffraction. In each ca
se, D-h phases were identified. The influence of the number, the lengt
h and the position of the grafted chains on the liquid crystal behavio
ur is discussed.
