title: Unique organization of solvent molecules within the hexameric capsules of pyrogallol[4]arene in solution.
abstract: The hexameric capsules of pyrogallol[4]arene (2b) were prepared in nondeuterated solvents in the absence and presence of adamantane carboxylic acid (3). The small encapsulated molecules were shown to occupy different sites within the same capsule. In the presence of 3, which are also encapsulated in the hexameric capsules, one observes yet another pair of signals for the encapsulated solvent molecules. Different NMR experiments enabled assignment of the different sites within the hexameric capsules of 2b.
