A New Fluoride Chemodosimeter Based on 3-Ether-Substituted 1, 8-Naphthalimide Derivatives

Abstract

We developed a new chromogenic and uorescent "off-on" 1,8-naphthalimide-derivated chemosensor 1 based on an F − -triggered desilylation reaction. It showed signi cant variations in UV/Visible absorption (510 nm) and uorescence emission wavelength (570 nm) for selective detection of uorides in tetrahydrofuran. Moreover, chemodosimeter 1-loaded test strips were successfully fabricated todetect uorides e ciently. Research Highlights1. A new sensor based on an F --triggered desilylation reaction 2. The test strips loaded probe 1 exhibited e ciently detection of uorides with signi cant changes in uorescence.
