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.
在水溶液中，传感器 DQAg 可以选择性地基于对共振的抑制来检测 Ag(+)，表现出 84nm 的大蓝移和发射强度比（F(481nm)/F(565nm)）的显著变化（R/R(0)高达 26 倍）。此外，由于 AgI 的沉淀使 DQAg 从配合物中释放出来，所得的 Ag-DQAg 也对碘化物阴离子表现出比其他阴离子更高选择性的比率和响应。
