Abstract

A new selective and sensitive colorimetric chemosensor 1 was developed for the sequential detection of Cu²⁺ and glutathione (GSH) in aqueous solution. The sensor 1 detected Cu²⁺ ion by an obvious color change from colorless to pale yellow. Importantly, 1 could be used to detect and quantify Cu²⁺ ion in water samples, and the detection limit (0.14 μM) of 1 for Cu²⁺ was much lower than the guideline (31.5 μM) of WHO in drinking water. Also, Cu²⁺-2·1 complex can be used as a colorimetric sensor for GSH via naked-eye. The detection limit for GSH was founded to be 2.98 μM. Moreover, the sensing ability of 1 for Cu²⁺ was supported by theoretical calculations.
