Abstract
A new strategy for the design of container molecules
is presented.
Sulfonylcalix[4]arenes, which are synthetic macrocyclic containers,
are used as building blocks that are combined with various metal ions
and tricarboxylate ligands to construct metal–organic “supercontainers”
(MOSCs). These MOSCs possess both endo and exo cavities and thus mimic
the structure of viruses. The synthesis of MOSCs is highly modular,
robust, and predictable. The unique features of MOSCs are expected
to provide exciting new opportunities for the exploration of their
functional applications
