A novel displacement-type colorimetric chemosensor for the detection of Cu2+ and GSH in aqueous solution

Abstract

A new and simple colorimetric chemosensor 1 was developed for the sequential detection of Cu2+ and glutathione (GSH) in aqueous solution. Receptor 1 detected Cu2+ 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 Cu2+ 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 Cu2+ (3.89 μM) was below the World Health Organization (WHO) guideline for drinking water (31.5 μM). Moreover, the resulting 1–Cu2+ complex could sequentially sense GSH, showing recovery of 1 from the complex.
