The term ‘supramolecular chemistry’ was defined by Lehn as ‘chemistry beyond the
molecule’, the aggregation of molecular or ionic entities to yield extensive arrays. Supramolecular chemistry is essentially the designed chemistry of the intermolecular
bond, encircling the traditionally distinct disciplines of organic, inorganic and
physical chemistry. Metal-organic frameworks have been shown to facilitate selective gas sorption and
selective binding of guest solvent molecules, with notable examples from the work of
Yaghi et al. created from the coordination of benzenepolycarboxylates to metal
centres. Authors including Herbstein have investigated the inclusion of solvent
molecules in the solid-state structure of trimesic acid, preventing the interpenetration
of this compound. Here, novel solvent inclusion compounds of hemimellitic acid,
the 1,2,3-trisubstituted relative of trimesic acid, are presented in which the hydrogen
bonded host network forms cavities in which solvent molecules reside. [Continues.]
