The synthesis of acyclic CB[n]-type host (1) is reported. By optimizing the placement of the sulfate groups nearby the electrostatically negative ureidyl C=O portals, the binding affinity of this class of receptors toward hydrophobic (di)ammonium guest molecules (5 – 23) is maximized. The x-ray crystal structures of 1•6a and 1•6d are reported.
