摘要：

The smallest members of the cucurbituril family, cucurbit[5]uril and the alkyl-cucurbit[5]urils, can be used as a building blocks, linked by metal ions to create supramolecular rings. The cavities found at the center of these rings have dimensions between 7 and 19 angstrom in width and 8.5 angstrom in depth. The partially substituted alkyl-cucurbit[5]urils present the most interesting supramolecular ring formation. This occurs as a result of selective coordination of metal ions to the carbonyl oxygens of the glycoluril moieties carrying alkyl substitution.
