There have been a number of previous reports of POCs that, rather than forming as monomeric architectures, undergo interpenetration to form mechanically interlocked molecules (MIMs). Often this interlocking significantly reduces the accessibility of the internal cavity space, limiting guest-binding potential. The incorporation of mechanically interlocked components on the periphery of the POCs could, however, be used to modify the structure and thus properties of the cages while theoretically leaving the cavity intact. Indeed, MIM architectures have previously been used to modulate the solubility, electronic and biological properties of molecular components. Although there have been reports of coordination cages functionalised with interlocked components, the introduction of MIMs onto organic cages has yet to be explored.
