molecule was designed and synthesized to prepare a supramolecular amphiphile with cucurbit[7]uril. In aqueous solution, the cucurbit[7]uril based supramolecular amphiphiles self‐assemble into well‐defined vesicles, and their disassembly can be achieved by addition of excess competitive agent 1‐adamantanamine hydrochloride. This vesicle functions as a new nanocapsule to encapsulate molecules within its

Provided are processes of preparing glycolurils and cucurbiturils using the glycolurils by microwave irradiation. Therefore, condensation and cyclization reactions for preparation of industrially widely applied cucurbituril derivatives, oxidation reaction for preparation of hydroxy-cucurbiturils, and condensation and cyclization reactions between glycolurils and paraformaldehyde or a formaldehyde solution can be efficiently performed in a short time.

The compound of composition [Mo3O4(H2O)6Cl3}2(Na2Cl⊂ C30H30N 20O10)]Cl3⋅14H2O (1) was prepared by evaporation of a hydrochloric acid solution containing NaCl, the trinuclear aqua complex [Mo3O4(H2O)9]4+, and the macrocyclic cavitand cucurbit[5]uril (C30H30N20O10). X-ray diffraction analysis demonstrated that the cucurbit[5]uril molecule is closed on both sides by the cluster cations through hydrogen bonding between the CO groups of the cucurbit[5]uril portals and the aqua ligands of the oxo cluster. The inner cavity of the supramolecular adduct includes an unusual ionic associate Na+...Cl...Na+. The sodium cations are coordinated by five carbonyl oxygen atoms of each portal of the macrocycle. Compound 1 is the first structurally characterized complex, in which the macrocyclic cucurbit[5]uril ligand is directly coordinated to the alkali metal cation.

Cucurbit[5]uril hydrochloride hydrate crystals with large water-filled channels transform to a highly stable layer structure via a single-crystal to single-crystal mechanism; 129Xe NMR showed that porosity in CB[5] samples depends critically on the method of preparation.
