Stimuli‐Responsive Self‐Sorting Hybrid Hydrogen‐Bonded/Metal‐Coordinated Cage.

The self‐assembly of a unique molecular container is reported: a hybrid hydrogen‐bonded/metal‐coordinated cage where both hydrogen‐bonding and metal‐coordination form the crucial part of the topology. The hybrid cage was prepared combining hydrogen‐bonded rosette motif and palladium(II)/platinum(II) coordination to a pyridine ligand. It was also shown that the hybrid cage could be prepared by integrative self‐sorting from simple components. For the first time the genuine dual character of the hybrid cage was manifested as both self‐assembling parts responded selectively to different stimuli (such as phosphine and cyanurate), which resulted in the disassembly of the cage.
