Self-assembly of ten molecules into nanometre-sized organic host frameworks
Article Abstract:
The self-assembly of ten species having four organic ligands attached to six metal ions produces a macromolecule with a hollow, nearly spherical supramolecular framework. X-ray crystallographic analysis of the macromolecule indicates that the compound has tetrahedral symmetry with a large central void in which guest molecules are incorporated. Four adamantyl carboxylate ions can be bound to the self-assembling cage. Volume weighted distribution analysis of particle size by a laser light scattering procedure suitably evaluates the particulate characteristics of the supramolecules.

A nanometre-sized hexahedral coordination capsule assembled from 24 components
Article Abstract:
Molecular capsules are closed, hollow frameworks where encapsulated molecules are isolated from international with external molecules. some molecular capsules have been prepared using conventional synthetic chemistry, but non-covalent synthesis has enabled capsules held together by hydrogen bonds to be created. Transition-metal-based coordination chemistry has been used to make a stable, nanometre-scale capsule from 24 smaller components.

Spontaneous assembly of ten components into two interlocked, identical coordination cages
Article Abstract:
A catenane comprising two cages was synthesized. Each cage is formed from two tridentate ligands bound together with three metal ions. One cage framework binds an aromatic ring, ad the two cage units bind one another during assembly via the formation of a quadruple aromatic stack. This results in the ten-component interlocked supermolecule.
