Abstract
A hydroxythiophene-bearing benzothiazole (HB) in phosphate buffer solution showed strong yellow fluorescence emission, which selectively and sensitively decreased by addition of IO4 −. The reaction between HB and IO4 − dramatically accelerated by UV irradiation. The fluorescence emission of HB was gradually recovered upon thermal heating of the IO4 −-adducted product, indicating IO4 − release. Using these properties, the solution containing HB and IO4 − has been used as a fluorescence-based security ink.
