Five additional macrocycles that allow Na+ ion-templated threading of guest units featuring a single urea or amide functionality?

Abstract
Five analogues of the macrocycle BPX26C6 are also capable of recognizing single urea and/or amide functionalities in the presence of templating Na+ ions. We have unambiguously confirmed the formation of such [2]pseudorotaxane complexes in solution through syntheses of the corresponding [2]rotaxanes.
