摘要
Molecular capsules consist of closed, hollow frameworks within which encapsulated molecules are isolated from interaction with external molecules', In this environment, otherwise reactive molecules can be stabilized(2-5). Although some molecular capsules have been prepared by conventional synthetic chemistry(1), recent progress in non-covalent synthesis has allowed the creation of capsules held together by hydrogen bonds(6-9). Hero we report the use of transition-metal-based coordination chemistry(10-19) to assemble a stable, nanometre-scale capsule from 24 small components: 18 metal ions and six triangular ligands, The capsule is roughly hexahedral and comprises six edge-sharing triangles with two metal ions on each edge. The internal space has a volume of 900 Angstrom(3) and is fully closed to all but very small molecules.
