Benzoselenadiazole fluorescent probes--near-IR optical and ratiometric fluorescence sensor for fluoride ion

Org Lett. 2014 Jan 17;16(2):354-7. doi: 10.1021/ol403082p. Epub 2013 Dec 30.

Abstract

A highly selective and sensitive near-IR optical sensor, benzoselenadiazole based diarylamine (TBS-HN), for fluoride (F(-)) has been designed and synthesized. TBS-HN also shows turn-on ratiometric fluorescence signaling in the presence of F(-) by inhibiting the excited state intramolecular proton transfer (ESIPT) processes.
