摘要：

A prismlike cage composed of six end-capped PtII ions, two panel-like ligands, and three pyrazine pillars assembles quantitatively through the template effect of a planar aromatic guest (see space-filling structure). The cage thus obtained is stable even when the template is removed. Other large aromatic molecules are also strongly bound and a β-diketone is shown to exist only in a planar enol form in the cage with the keto-enol tautomerization being almost completely suppressed.
