Abstract

A unique, readily synthesised, upper-rim 1,3-difunctionalised calix[4]arene is reported; equipped with a fluorophore and an alkyne it mediates the efficient chemoselective detection of Au³⁺. Its ability to detect Au³⁺ is not perturbed by Au⁺ or excess competing and or contaminating metal e.g. platinum, cadmium, mercury, silver, sodium, magnesium or potassium cations.
