We have designed and synthesized a new carbocation precursor (carbinol) based on bis-pyrene derivative. The carbinol can be transformed to stablecarbocations with quenched fluorescence and long wavelength absorption. The stablecarbocations can be further used as fluoride anion detection in acidic environment, which show both chromogenic and fluorogenic responses in the presence of fluoride anion
