¹³³Cs Diffusion NMR Spectroscopy: A Tool for Probing Metal Cation–π Interactions in Water

Abstract

Association phenomena: 133Cs and 1H diffusion NMR experiments give evidence of a 1:1 inclusion complex between p-sulfonatocalix[4]arene and a cesium ion in water (see picture); the complex is stabilized by cation–π interactions.
