A terpyridine-based supramolecular cage was successfully synthesized by the self-assembly of a hexapodal metal-organic ligand with Zn 2+ . This metallo-cage exhibited two large parallel planes on the top and bottom with diameters close to 6 nm and a face-to-face distance close to 3.5 nm, thus possessing a large cavity. Electrospray ionization mass spectrometry (ESI-MS), nuclear magnetic resonance (NMR), two-dimensional nuclear Overhauser (2D-NOESY), and diffusion-ordered (DOSY) spectroscopies as well as transmission electron microscopy (TEM) and atomic force microscopy (AFM) measurements, unambiguously supported the formation of a supramolecular cage. Furthermore, the corresponding metal-organic gel was felicitously prepared in CH 3 CN/H 2 O and displayed good adsorption performance for dye molecules.
