EXPLORATION OF BINDING SELECTIVITIES OF CUCURBIT[N]URILS WITH ALKALI METAL IONS VIA ESI-MS
Cucurbit[n]urils, or CBn, where n = 5, 6, 7, 8 or 10 are “molecular containers” well-suited for binding of a wide array of molecules, and are of immense interest in drug delivery, photochemical reactions and catalysis. Of considerable interest in understanding the fundamental properties of these molecules are their binding properties with metal ions. In our study, we have explored the binding selectiviries of CB5, CB6 and CB7 with alkali metal ions via electrospray ionization (ESI) mass spectrometry in aqueous solutions. We find that the CBn bind with one or two alkali metal ions, and the binding selectivity increases with increasing ionic radii.
