A series of Rebek imide receptors with naphthalene or heteroaromatic platforms attached by amide or ester linkers have been prepared from the corresponding acyl chloride or anhydride; the X-ray crystal structure of the receptor-derived anhydride reveals a supramolecular H-bonded helix formation in the crystal; the complexes of adenine bound to the receptors by Hoogsteen H-bonding are found to be stabilised by stacking with a methylquinolinium ion, but destabilised by stacking with a perfluorinated naphthalene.
