Mono-and polynuclear aqua complexes and cucurbit[6]uril:Versatile building blocks for supramolecular chemistry

摘要

The review surveys new data on the directed construction of supramolecular organic-inorganic compounds from macrocyclic cavitand cucurbit[6]uril(C_(36)H_(36)N_(24)O_(12))and mono-and polynuclear aqua complexes.Due to the presence of polarized carbonyl groups, cucurbit[6]uril forms strong complexes with alkali, alkaline earth and rare-earth metal ions, and hydrogen-bonded supramolecular adducts with cluster and polynuclear aqua complexes of transitional metals.A wide variety of supramolecular compounds and their unique structures are described.
