| Abstract: A novel pyrrole-based hydrazone has been synthesized for colorimetric and fluorescent turn-on detection of Hg2+ ions. A 1:1 binding ratio of the Hg2+ complex has been obtained from Job's plots and MS data. The coordination mode was systematically investigated by 1H NMR, time-resolved fluorescence spectroscopy, and density functional theory (DFT) calculations. The limit of detection of 1 for Hg2+ was as low as 45 nmol·L-1 with an association constant of 5.78×108 L·mol-1. It is worth noting that the response of 1 to Hg2+ was good in a pH range of 4.0 to 10.0. In addition, owing to the existence of the morpholine group, the probe can detect lysosomal Hg2+ in HeLa cells. |
