Abstract

The first example of the detection of Ag^I ions using supramolecular chemistry is demonstrated, in which two thiacalix[4]arene ligands are linked by analyte Ag^I ions and then coordinate to Tb ^III ions to form a luminescent ternary complex, Ag^I ₂·Tb^III₂·TCAS₂, enabling the detection of Ag^I at concentrations as low as 3.2×10^-9 M.
