Abstract

A new bi-functional chemosensor 1 based on 3,5-dichlorosalicylaldehyde and 2-(methylthio)aniline has been synthesized. It can detect Cu²⁺ with a color change from pale yellow to dark yellow in aqueous solution. The selective mechanism of 1 for Cu²⁺ was proposed to be the enhancement of the intramolecular charge transfer (ICT) band, which was explained by theoretical calculations. The sensor 1 could be used to detect and quantify Cu²⁺ in water samples. In addition, the sensor 1 displayed “turn-on” fluorescence response only to Zn²⁺, based on an effect of chelation-enhanced fluorescence (CHEF). Therefore, 1 can serve as a ‘single sensor for two different targets’ with dual modes.
