Abstract

We report a new sensor, 1, for sequentially detecting Zn²⁺ and CN^- based on fluorescence. Sensor 1 was prepared through the reaction of 3-aminobenzofuran-2-carboxamide with 4-diethylaminosalicylaldehyde. Sensor 1 showed a selective "off-on" fluorescent response toward Zn²⁺, distinguishing Zn²⁺ from Cd²⁺. The limit of 1 (0.35 μM) for monitoring Zn²⁺ is lower than the World Health Organization (WHO) guideline (76 μM) for water available for drinking. Importantly, sensor 1 could sense Zn²⁺ in living cells and aqueous media. In addition, the resulting 1-Zn²⁺ complex functioned as an efficient "on-off" sensor for CN^-. The mechanisms of 1 for detecting Zn²⁺ and CN^- were explained by spectroscopic, spectrometric, and theoretical studies.
