Abstract

A feasible double-site near-infrared (NIR) fluorescent probe Q5 based on xanthenes was developed. Probe Q5 showed clearly HSO3− induced changes in the fluorescence ratio of two well-separated NIR and VIS peaks, showing excellent selectivity compared with other analytes. And the detection limit of the probe for HSO3− was found to be 89 nM. Furthermore, fluorescence imaging experiments of HSO3− in CEM cells revealed that the probe has potential application value in biological systems. [ABSTRACT FROM AUTHOR]

Abstract

A new probe (RosN3), which displayed excellent selectivity to H2S in mixed aqueous media, was synthesized. This method employed the H2S-mediated reduction of azides to amines, resulting in fluorescence quenching. The probe exhibited high H2S 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]
