An Anion-Modulated Three-Way Supramolecular Switch that Selectively Binds Dihydrogen Phosphate, H2PO4

An anionic three‐way switch: A bipyridyl bis(urea)‐based anion receptor that is highly selective for dihydrogen phosphate demonstrates spectroscopically distinct anion‐bound conformations toward halides and select oxoanions. 1H NMR studies show the differing anion‐induced conformations are reversibl...

Summary:An anionic three‐way switch: A bipyridyl bis(urea)‐based anion receptor that is highly selective for dihydrogen phosphate demonstrates spectroscopically distinct anion‐bound conformations toward halides and select oxoanions. 1H NMR studies show the differing anion‐induced conformations are reversible allowing this system to function as a three‐way molecular switch.
