A Simple Fluorescence Turn‐on Probe for the Detection of Hg 2+ Ion in Aqueous Solution and Soil With AIE and ICT Mechanisms

A Simple Fluorescence Turn‐on Probe for the Detection of Hg 2+ Ion in Aqueous Solution and Soil With AIE and ICT Mechanisms

A novel fluorescent probe TSA for the high selectivity of mercury (Hg 2+ ) ion has been explored, which was obtained by two‐step synthesis. Probe TSA was barely emissive in HEPES buffer. In the presence of Hg 2+ ion, the dithioacetal unit in probe TSA was hydrolyzed to be formyl group, consequently...

description A novel fluorescent probe TSA for the high selectivity of mercury (Hg 2+ ) ion has been explored, which was obtained by two‐step synthesis. Probe TSA was barely emissive in HEPES buffer. In the presence of Hg 2+ ion, the dithioacetal unit in probe TSA was hydrolyzed to be formyl group, consequently causing the intense sky‐blue emission via aggregation‐induced emission and intramolecular charge transfer mechanisms. Moreover, probe TSA was potential to detect Hg 2+ ion in dyeing wastewater and clay soil.
