CONFORMATIONAL BEHAVIOR AND BINDING-PROPERTIES OF NAPHTHALENE-WALLED CLIPS

The conformational behavior and binding properties of various clip-sha ped receptor molecules, based on the building block diphenylglycoluril , were studied by NMR, X-ray analysis, and computational techniques. T he conformation and the binding properties of these clips are dependen t on the number and type of side walls. Host molecules with two naphth alene side walls and with methoxy groups at the 2- and 7-position are able to bind aromatic guests and silver ions by an induced-fit mechani sm.
