A dual channel chemodosimeter for Hg2+ and Ag+ using a 1,3-dithiane modified BODIPY

Addressing of multiple-metal ions on a single platform

“…Zhang et al [82] developed a dual-channel chemodosimeter 53 based on BODIPY for the detection of Hg 2+ and Ag + ions. The compound had been modified with 1, 3-dithiane moiety to yield the desired probe.…”

Pyridyl Azo‐Based Progelator in Selective Sensing of Hg2+ and Ag+ Ions via Sol to Gel Conversion

“…Furthermore, the position of Hc proton ( ortho to the pyridyl ring N‐atom) was almost unperturbed and there was small downfield chemical shift of the Ha proton. These observations suggested that the pyridine was not involved in chelation with Ag + rather the thio ether segments were involved in interaction with Ag + ions . Ag + ions and thio ether interaction led to the gelation prior to the dethioacetalization, and that is why the gelation process in was reversible in presence of KCl.…”

A fluorescence “turn-on” chemosensor for Hg2+and Ag+based on NBD (7-nitrobenzo-2-oxa-1,3-diazolyl)

“…Until now, only a few "turn-on" chemosensors that can detect simultaneously both mercury and silver ion have been reported. 19,[31][32][33] NBD (7-nitrobenzo-2-oxo-1,3-diazolyl) is a well-known uorophore and frequently adopted in designing a uorescent chemosensor owing to its distinct spectral properties. [34][35][36][37][38][39][40][41] As for the receptor, N,N 0 -dimethyl ethylene amine group offers a good possibility of chelation with transition metal ions.…”
