文摘

A novel tripodal ligand L that only has a syn conformer has been designed and synthesized. Different Ag₃L₂ metallocages can be effectively assembled from such concave ligands and different Ag(I) salts. ESI-MS research indicates that a Ag₃L₂ metallocage can encapsulate different anions selectively, in which the encapsulation capacity is as follows: NO₃^– > ClO₄^– > SO₄^2–; moreover, selective encapsulation of NO₃^– from a mixture of NO₃^– and ClO₄^– has been observed.
