A supramolecular fluorescence probe for caffeine.
[structure: see text] Supramolecular sensing is rather limited to charged analytes. This report describes a practicable assay for caffeine, which employs a competitive "indicator-displacement" approach and allows detection by fluorescence. A simple analytical protocol is described that allows quantitation of caffeine in beverages.
