Abstract
- A new probe (RosN<subscript>3</subscript>), which displayed excellent selectivity to H<subscript>2</subscript>S in mixed aqueous media, was synthesized. This method employed the H<subscript>2</subscript>S-mediated reduction of azides to amines, resulting in fluorescence quenching. The probe exhibited high H<subscript>2</subscript>S selectivity over other common anions and biothiols. The detection limit was measured to be 0.25 μM. Furthermore, the live cell imaging results demonstrated its potential for practical application in biological systems. [ABSTRACT FROM AUTHOR]
