Tubular mesophases: liquid crystals consisting of macrocyclic molecules

Abstract
The hexa-(p-n-dodecyloxybenzoyl) derivatives (1b), (2b), and (3b) of the macrocyclic polyamines [18]-N6, [24]-N6O2, and [27]-N6O3 display a liquid crystal phase in which the macrocyclic units are stacked, forming a tubular mesophase.
