ResumoA molecular cage, macrobicycle 2, containing amide and pyrrole groups as hydrogen-bonding donors and imine groups as hydrogen-bonding acceptors has been synthesized. Compound 2 was found to recognize tetrahedral oxyanions with high affinities, such as H2PO4–, HSO4–, SO42–, and HP2O73–, as well as the spherical halide anions, in chloroform. A single-crystal X-ray diffraction analysis revealed that compound 2 formed a 1:1 complex with H2PO4– in the solid state.
