title: Ratiometric fluorescent sensor for silver ion and its resultant complex for iodide anion in aqueous solution.
abstract: In aqueous solution, sensor DQAg can selectively detect Ag(+) based on inhibition of the resonance, demonstrating a large hypsochromic shift of 84 nm and remarkable changes in the ratio (F(481 nm)/F(565 nm)) of the emission intensity (R/R(0) up to 26-fold). Furthermore, the resultant Ag-DQAg also displays a ratiometric and highly selective response to iodide anion over other anions due to the liberation of DQAg from the complex by precipitating AgI.
