A combination of hydrophobic forces and guest templation drive the assembly of cavitands into molecular capsules. Encapsulated guests such as dibenzyl ketones reside in an essentially dry environment, and upon irradiation, undergo rearrangement processes that are templated by the shape of the 1 nm × 2 nm cavity.

The synthesis of a water-soluble, deep-cavity cavitand is reported. A blend of molecular curvature and amphiphilicity, this molecule has a hydrophobic concave surface and a hydrophilic convex surface. As a result, in aqueous solution and in the presence of a guest molecule, the host self-assembles to form a capsular assembly with an interior cavity large enough to entrap steroidal guests.

Three families of tris-pyridyl methanol ligands were synthesized. An analysis of the Zn2+ binding properties of the ligands revealed that both steric and electronic properties of the pyridine substituents, as well as the nature of the group on the tertiary alcohol oxygen, control the thermodynamics and kinetics of complex formation.
