    • 3 or the liquid membrane, NPOE. The X-ray structure of 1·KCl shows that the salt is bound inside the receptor as a contact ion pair with many ideal noncovalent interactions. It seems unlikely that KCl would bind strongly to the receptor if it were a solvent-separated ion pair. Even if this were the case, the fundamental conclusion of the study would be unchanged; for example, the polarity of a receptor-salt complex will be lowered if the salt is bound to the receptor as an associated ion pair (a contact ion pair is the best case). A complex with lowered polarity is more likely to diffuse faster through the liquid membrane.
