Abstract

A multifunctional colorimetric chemosensor 1, N-(2-((2,4-dinitrophenyl)amino)phenyl)-2-((2-hydroxyethyl)amino)acetamide was synthesized and used to sense Cu²⁺and S²⁻in aqueous solution. The sensor 1 showed highly selective colorimetric responses to Cu²⁺and S²⁻by immediately changing its color from pale yellow to light green and pink, respectively, without any interference from other metal ions and anions. Especially, 1 can detect Cu²⁺(10.1 μM) below the guideline (31.5 μM) of WHO. Moreover, the sensor 1 could be used to quantify Cu²⁺ion in water samples. The sensing mechanism of Cu²⁺by 1 were proposed to be a metal-to-ligand charge-transfer (MLCT) with the experimental results and theoretical calculations, and that of S²⁻by 1 proposed to be a deprotonation process.
