Naphthothiazole-based highly selective and sensitive fluorescent and colorimetric chemosensor for detection of pollutant metal ions
A new fluorescent and colorimetric chemosensor based on naphthothiazole S1 was synthesized and its applications as chemosensor for the selective sensing of pollutant metal ions in water resources and/or biological systems were investigated. Sensor S1 showed great selectivity for Zn 2+ and Sn 2+ over...

Zusammenfassung: | A new fluorescent and colorimetric chemosensor based on naphthothiazole
S1
was synthesized and its applications as chemosensor for the selective sensing of pollutant metal ions in water resources and/or biological systems were investigated. Sensor
S1
showed great selectivity for Zn
2+
and Sn
2+
over other metal ions. The Job's plot showed a 1:1 stoichiometry between
S1
with Zn
2+
and Sn
2+
. Interaction mode of sensor
S1
with Zn
2+
ion was further approved by single crystals X-ray crystallography method. The detection limit for the fluorescent chemosensor
S1
toward Zn
2+
and Sn
2+
were respectively 2.60 10
8
M and 8.21 10
8
M.
The presented small molecule sensor can be used successfully for selective detection of Zn
2+
and Sn
2+
ions in aqueous media. |
