A ditopic ion-pair receptor based on stacked nucleobase quartets.
Pass the salt, please! State-of-the-art computations indicate that the stacking complex of a guanine quartet and an adenine quartet (G(4)A(4)) can function as a potent ditopic receptor for NaCl in aqueous solution (see picture; Na(+), Cl(-) yellow, O red, N blue, C black, H white).
