Abstract

Herein, we report on a new ¹⁹F MRI probe for the detection and imaging of H₂O₂. Our designed 2-fluorophenylboronic acid-based ¹⁹F probe promptly reacted with H₂O₂ to produce 2-fluorophenol via boronic acid oxidation. The accompanying ¹⁹F chemical-shift change reached 31 ppm under our experimental conditions. Such a large chemical-shift change allowed for the imaging of H₂O₂ by ¹⁹F chemical-shift-selective MRI.
