A novel imidazolium-functionalized BINOL fluorescent receptor <b>R-1</b> was developed as a multifunctional receptor for both chromogenic and chiral anion recognition. The different fluorescent responses and color changes of <b>R-1</b> could be applied to the detection of fluoride and acetate ions by the naked eye. Furthermore, the chiral recognition of the two enantiomers of α-amino carboxylates was also studied, and <b>R-1</b> displayed a remarkable binding ability for the <i>t</i>-Boc alanine anion with an interesting enantioselectivity (<i>K</i><sub>L</sub>/<i>K</i><sub>D</sub> = 4.5).
