Two triangular prismatic cages were synthesized by combining a trishydrazide and two bisformyl precursors in strongly acidic water, where the dynamic nature of hydrazone was turned ON. An anionic guest used as template to drive cage formation. Performing counterion exchange removed both Brønsted acid. The removal latter afforded cages' kinetic inertness turning OFF reversibility hydrazone. can thus be for recognizing various guests water without observable degradation, driven hydrophobic effect. Upon being accommodated within cavities, an anthracene derivative protected from UV-stimulated oxidation, which would occur otherwise bulk solution protection host.

Published: Oct. 1, 2024

Abstract Organic molecular cages with low symmetry are promising to generate complex chemical environments for recognition and catalysis. Herein, a new triangular prism cage three rigid 8‐aminoquinoline‐2‐carboxylic acid derivatives as edges were synthesized. This possesses reduced contains both secondary amine amide hydrogen donating groups recognition. It could bind anions, such NO 3 − , AcO F moderate affinity.
