文摘

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鈥?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 鈥減etals鈥?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鈭捪€ interactions between the aromatic side-arms, as well as the Ag⁺鈥撓€ interactions, are crucial for double- and tetra-armed cyclens to work as argentivorous molecules.
