Herein we describe a large capsule-like bis-calix[4]pyrrole 1, which is able to host concurrently two dihydrogen phosphate anions within a relatively large internal cavity. Evidence for the concurrent, dual recognition of the encapsulated anions came from <sup>1</sup>H NMR and UV-vis spectroscopies and ITC titrations carried out in CD<sub>2</sub>Cl<sub>2</sub>/CD<sub>3</sub>OD (9/1, v/v) or dichloroethane (DCE), as well as single crystal X-ray diffraction analyses. Receptor 1 was also found to b ...[more]
