Both discotic molecules and certain linear polymers form columnar hexagonal mesophases. Whereas the dislike structure of the macrocycle 1 is dictated by the molecular shape, in polymer 2 it is presumably enforced by a helical folding of the polymer's main chain induced by the side chains (bottom right).
