The Lewis acidic uranyl center and the amide units of receptor 1 bind the anion of the hydrophilic, biologically relevant salt KH 2 PO 4 specifically, and simultaneously the crown ether units bind the cation. The complexation properties of 1 were studied with NMR spectroscopy, mass spectrometry, and cyclic voltammetry. The recognition demonstrated for this simple salt could be of great importance for membrane transport, extraction, and sensor technology.
