Metal Actuated Ring Translocation Switches in Water

Abstract : Among a series of metal ions in water, silver is the only one to remotely and reversibly switch cucurbit[7]uril (CB[7]) movements (translocation or uptake) on a rigid and linear three station viologen phenylene imidazole (V-P-I) derivative, avoiding undesired pH actuation. H-1 NMR, UV-vis spectroscopy, mass spectrometry, ITC, and modeling were combined to show that ring translocation or uptake along a molecular thread is possible in water by Ag+ as a metal stimulus.
