A comparable receptor (in terms of binding site) is described in Ref. 8, although a quantitative association constant is not reported for urea (methylated urea derivatives are dealt with quantitatively). The structure also lacks imine nitrogens on the outer core thus restricting the binding possibilities within the cavity of the receptor.
