A Bambusuril Receptor Binds Charge Diffuse Anions in Water at Picomolar Concentrations
Angewandte Chemie, EarlyView.Synthesis of a bambusuril macrocycle with unprecedented binding affinity for several charge diffuse anions, including iodide, perchlorate, nitrate, and perrhenate, in neutral phosphate buffer is reported. The macrocycle exhibits selectivity for charge diffuse over charge dense anions exceeding seven orders of magnitude.
