Hydrogen bonds and ππ stacking stabilize a supramolecular cage (depicted schematically on the right) constructed from five components, namely two trifurcated trisammonium cations and three ditopic crown ether molecules. This molecule is a remarkable example of a programmed supramolecular system: the information essential for the cage's assembly is stored in the covalent frameworks of the two building blocks.
