Fluorogenic supramolecular complexes formed between pyrenyl-β-cyclodextrin and glyco-rhodamine for the selective detection of lectins.

Fluorogenic supramolecular complexes formed between tubular-shaped pyrenyl-β-cyclodextrins and glyco-rhodamine are determined to respond to a selective lectin with 'turn-on' fluorescence with excellent selectivity over a range of competing species.
