Abstract

A new naphthalimide-based derivative L bearing an S-benzyldithiocarbazate moiety was synthesized as an “off–on” probe for Ag⁺. The new probe has high binding selectivity for Ag⁺ in water media with a detection limit of Ag⁺ down to 270 nM. Based on the Ag⁺-induced inhibition of a PET process and restriction of C [double bond, length as m-dash] N rotation, the coordination mode of 1 : 1 between L and Ag⁺ was proposed.
