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

We developed a new chromogenic and fluorescent "off-on" 1, 8-naphthalimide-derivated chemosensor 1 based on an F - -triggered desilylation reaction. It showed significant variations in UV/visible absorption (510 nm) and fluorescence emission wavelength (580 nm) for selective detection of fluorides in THF/H 2 O system (v/v, 50:50). Moreover, chemodosimeter 1-loaded test strips were successfully fabricated todetect fluorides efficiently.
