Abstract

We describe a [2]rotaxane molecule that exhibits distinct signals in its ¹H NMR spectra upon the complexation of physiologically important Li⁺, Na⁺, Mg²⁺ and Ca²⁺ ions; thus, the identification of these metal ions in solution is possible from the analysis of a single ¹H NMR spectrum of a single molecular sensor.
