Abstract

A new fluorescent sensor 1, based on the naphthalimide chromophore and thioether-rich crown receptor, exhibited dual signaling behaviors for Hg ²⁺ and Ag⁺ in aqueous solution. Upon addition of Hg ²⁺, the fluorescence intensity enhanced in a linear fashion with a quantum yield increase of about 5-fold. Moreover, with the 1-Hg²⁺ complex, Ag⁺ was easily recognized by a marked fluorescence quenching. The living cells image experiments demonstrate the value of sensor 1 in fluorescent visualization of Hg²⁺ ions in biological systems.
