Cyclotricatechylene hexaester

Fig. 6.1.4. (a) Cyclotricatechylene hexaesters, the cores of which are cone-shaped (Malthete and Collet ), (b) hexa-(p-n-dodecyloxybenzoyl) derivative of macro-cyclic polyamines which is hollow at the centre (Lehn, Malthete and Levelut ). Both (a) and (b) show columnar mesophases the latter mesophase has been... 

Columnar mesophases are also formed when the flat core of the molecule is replaced by a conical one as in the cyclotricatechylene hexaesters (fig. 6.1.4(a)). With macrocyclic molecules, which are hollow at the centre (fig. 6.1.4(A)), the columns are in the form of tubes these mesophases have been described as tubular . ...
