A Novel BODIPY-Derived Fluorescent Sensor for Sulfite Monitoring.

ABSTRACT: Sulfur dioxide (SO₂) is commonly employed as an antioxidant and preservative in food processing, but excessive intake of SO₂ can pose significant health risks. Therefore, accurate detection of sulfite content in food is crucial for ensuring food quality and safety. A novel fluorescent probe, BODIPY-Y, composed of a BODIPY derivative and an ethyl cyanoacetate group linked by a carbon-carbon double bond, was synthesized for detecting sulfur dioxide derivatives. When the BODIPY-Y probe interacts with SO₃^2-, the probe exhibits enhanced fluorescence at 514 nm. Spectrometric experiments show that the probe exhibits high sensitivity (LOD: 0.263 μmol/L), a fast response time (50 s) and excellent selectivity for SO₃^2-. Mechani
