Published in the Journal of the American Chemical Society (Sessler, J.L.; Kim, S.K.; Gross, D.E.; Lee, C.; Kim, J.S.; Lynch, V.M. J. Am. Chem. Soc., 2008, 10, 1021), this ion-pair receptor has both cation- and anion-recognizing sites. These structures have the potential in salt solubilization, ion extraction, and through membrane transport.
