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.
