Cucurbit[n]urils are a family of molecular container hosts bearing a rigid hydrophobic cavity and two identical carbonyl fringed portals. They have attracted much attention in supramolecular chemistry because of their superior molecular recognition properties in aqueous media. This review highlights the recent advances and challenges in the field of cucurbit[n]uril-based coordination chemistry. It not only presents progress in the knowledge of such macrocyclic compounds, which range from simple to complicated architectures, but also presents new routes of synthesis and their advantages in hybrid porous solids. The concept of structure "inducer" for their structural design to achieve predictable structures and controlled pores is described. The large pore sizes and hydrophobic cavities of these compounds that lead to unprecedented properties and potential applications are also discussed.

“…Transition-metal ions normally form hydrates or complex fragments and interact with CB[ n ] through H-bonding interactions . Only a few exceptions in which transition-metal ions attach to the portal carbonyl groups of CB[ n ] via coordinative bonds have been documented, even though extra transition-metal complex moieties were observed in the crystal lattice as structure inducers . To the best of our knowledge, complex 1 represents the first example of a crystalline supramolecular hybrid solid based solely on noble-metal ions and CB[ n ].…”

Monodispersed silver nanoparticles (Ag(0) NPs) have been first prepared on the basis of a postsynthesis via mild reduction from a new crystalline supramolecular hybrid solid assembled from Ag(+) ions and decamethylcucurbit[5]uril (Me10CB[5]). Uniform growth of nearly spherical Ag(0) NPs with an average size of ca. 4.4 nm was observed on the organic Me10CB[5] support to form Ag@Me10CB[5] composite material. The as-synthesized composite material was characterized by a range of physical measurements (PXRD, TGA, XPS, ICP, TEM, etc.) and was further exploited as a heterogeneous catalyst for the reduction of various nitrophenols in the presence of NaBH4. The kinetics of the reduction process was monitored under various experimental conditions. The Ag@Me10CB[5] composite material showed excellent catalytic performance over the reduction reactions and remained active after several consecutive cycles.

“…Later, a number of researchers reported the coordination of cucurbiturils with metal ions, most of which studied their coordination with alkali metals, alkaline earth metals and rare earth metals. There are few studies on the direct coordination of cucurbiturils with transition metals and the direct coordination of cucurbiturils with Cu 2+ and Zn 2+ ions has been rarely studied …”

A Study on the Coordination of Fully Substituted Cyclopentano Cucurbit[5, 6]uril with Copper and Zinc Ions

Herein, we report the supramolecular self‐assembly of fully substituted cyclopentano cucurbit[5]uril (CyP5Q[5]) and cucurbit[6]uril (CyP6Q[6]) with Cu(ClO4)2 and Zn(ClO4)2 in a solution of formic acid. Single crystal X‐ray diffraction analysis showed that CyP5Q[5]‐Cu(ClO4)2 forms a W‐type molecular capsule complex and CyP5Q[5]‐Zn(ClO4)2 forms alternate Z‐type and V‐type molecular capsule complexes. Both CyP6Q[6]‐Cu(ClO4)2 and CyP6Q[6]‐Zn(ClO4)2 form Z‐type molecular capsule complexes. These two coordination systems have the same unit cell parameters and are isomorphic complexes. In these four systems the ClO4– ions are coordinated around the cucurbituril via ion‐dipole interactions and induce the self‐assembly of the cucurbituril and metal ions.
