摘要:
In this article, a novel "off-on" fluorescent probe 2-(pyren-1-ylmethylene)-1H-indene-1,3(2H)-dione (PID) for Hg2+ was designed and synthesized. The selectivity, concentration titration, pH titration, time dependence, limit of detection, and recognition mechanism of PID for Hg2+ in CH3CH2OH/H2O solution were also investigated. The results indicated that PID exhibited high selectivity, sensitivity, and fast response to Hg2+, and the limit of detection was as low as 20.7 nmol/L. In addition, PID could work in a wide pH range, and the determination of Hg2+ in water samples showed that it could be used as a potential detection tool in practical application.
