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.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules,...
