Seven double-armed cyclens bearing two aromatic side-arms, at the 1- and 7-positions of the cyclens, were prepared via three steps from dimethyl 2,2′-iminodiacetate. The X-ray structures of the Ag+ complexes and Ag+-ion-induced 1H NMR spectral changes suggest that the two aromatic side-arms cover the Ag+ ions incorporated in the ligand cavities, as if the aromatic ring petals catch the Ag + ions in the way a real insectivorous plant (Venus flytrap) catches insects, using two leaves. It is also reported that the CH-π interactions between the aromatic side-arms, as well as the Ag+-π interactions, are crucial for double- and tetra-armed cyclens to work as argentivorous molecules.
