2-Hydroxy benzothiazole modified rhodol: aggregation-induced emission and dual-channel fluorescence sensing of Hg2+ and Ag+ ions

The sensitive detection and quantification of heavy and transition metal ions are particularly important. Among them, mercury(II) (Hg2+) and silver(I) (Ag+) ions, as the most ubiquitous heavy metal ion pollutants, are difficult to discriminate in the same system because of their similar reactions and coordination abilities. Herein, we designed and synthesized a “turn-on” chemosensor, RBTP, which is an intergrant of rhodol and 2-hydroxy...
