    • note
    • [11] In this system, the amide bond must always point directly away from the pyrrolic hydrogen-bonding array of the calixpyrrole, making it unlikely that the amide NH contributes significantly to the anion chelation process. In fact, the chemical shift of the amide proton alters by only 0.5 ppm in the presence of 6.0 molar equiv of chloride anions.
