Supramolecular control over PC formation. (A) Chemical structures of the guest molecule pyr and the host cage A (the chemical structure of only one edge of the tetrahedral cage A is shown for clarity). (B) Schematic illustration of the reversible control over PC formation on AuNPs, using a supramolecular host–guest complex between negatively charged pyr and positively charged cage A.
