Using Oppositely Charged Ions To Operate a Three-Station [2]Rotaxane in Two Different Switching Modes
摘要:
A [2]rotaxane undergoes switching of its bis-p-xylyl-[26]crown-6 (BPX26C6) component away from its guanidinium station toward its 2,2'-bipyridyl and carbamate stations upon the addition and removal of Zn2+ and PO43- ions, respectively.
A Guanidinium Ion-Based Anion- and Solvent Polarity-Controllable Molecular Switch
摘要:
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.
