Molecular recognition of anionic substrates. Binding of carboxylates by a macrobicyclic coreceptor and crystal structure of its supramolecular cryptate with the terephthalate dianion

Abstract

The macrobicyclic polyammonium receptor molecule 1–6H+ binds dicarboxylate substrates with linear recognition and forms with terephthalate a very stable dianion cryptate the crystal structure of which has been determined.
