A novel displacement-type colorimetric chemosensor for the detection of Cu2+ and GSH in aqueous solutionElectronic supplementary information (ESI) available: Experimental procedures and additional experimental data. See DOI: 10.1039/c6ra12368f
A new and simple colorimetric chemosensor 1 was developed for the sequential detection of Cu 2+ and glutathione (GSH) in aqueous solution. Receptor 1 detected Cu 2+ ions by changing its color from colorless to yellow. Based on UV-vis titrations, Job plot, and ESI-mass spectrometry analysis, the sens...

was developed for the sequential detection of Cu
2+
and glutathione (GSH) in aqueous solution. Receptor
1
detected Cu
2+
ions by changing its color from colorless to yellow. Based on UV-vis titrations, Job plot, and ESI-mass spectrometry analysis, the sensing mechanism for Cu
2+
was proposed to be the enhancement of the intramolecular charge transfer band, which was further explained by theoretical calculations. The detection limit of
1
for Cu
2+
(3.89 μM) was below the World Health Organization (WHO) guideline for drinking water (31.5 μM). Moreover, the resulting
1
-Cu
2+
complex could sequentially sense GSH, showing recovery of
1
from the complex.
A new selective and sensitive chemosensor

for the sequential detection of Cu
2+
and GSH
via
