Two trimeric units of calix[4]arene di-methoxycarboxylic acid form a six-pointed star architecture that, in turn, generates triple helical aquatubes which intermesh between themselves by aromatic–aromatic interdigitation of the macrocycle.

Pyrene-appended calix[4]arenes 6-8 bearing an increasing number (from 2 to 4) of 'pyrene amide' residues have been prepared. Their fluorescence behaviour has been investigated to show dependence on the number of pyrene groups. Their behaviour as fluorophores is also described. (c) 2005 Elsevier Ltd. All rights reserved.
