A pyridyl-functionalized cavitand: Starting point for hydrogen-bond driven assembly of heterodimeric capsules

The directed assembly of derivatized cavitands into nano-sized supramolecular hosts is of considerable interest. This manuscript describes the synthesis and structural characterization of a pyridyl-functionalized cavitand that, in principle, can act as one half of a large number of hydrogen-bonded heterodimeric capsules when matched with a variety of suitably functionalized cavitands.
