A rapid fluorescent probe based on the conjugate of chromone and benzothiazole moiety was presented, which could selectively respond to HSO3- over other common anions and thiols. The function of the probe relies on nucleophilic addition to break down the pi-conjugation. The probe can be used as a signal tool to determine HSO3- levels in sugar-based food and living cells.
