We present herein the development of a new polycationic cyclophane: the red box, second in a series of hydrazone-based analogues of the well-known organic receptor cyclobis(paraquat-p-phenylene) cyclophane (blue box). The macrocycle has been prepared in an excellent yield in aqueous media, and shows both a remarkable pH-responsiveness and unusual hydrolytic stability of the two hydrazone C=N bonds, associated with charge delocalization of the amine lone pair. Whilst in aqueous media the red box is able to complex a variety of aromatic substrates, both in its acidic and basic form, in organic media the cyclophane is only able to capture those in the acidic form, resulting in supramolecular pHresponsiveness. |
