A guanidinium ion-based anion- and solvent polarity-controllable molecular switch.
The macrocycle bis-p-xylyl[26]crown-6 (BPX26C6) is capable of complexing guanidinium ions in a [2]pseudorotaxane-like manner in solution. A corresponding molecular switch can be operated through changes in solvent polarity or the addition and removal of halogen and acetate anions.
