Abstract

A simple colorimetric receptor 1 based on the combination of N-(5-nitro-2-pyridyl)-1,2-ethanediamine and 4-(diethylamino)-2-hydroxybenzaldehyde was synthesized for the sequential detection of Cu^2 + and CN⁻. The receptor 1 showed a distinct color change toward Cu^2 + from colorless to yellow. The detection limit of 1 for Cu^2 + (0.88 μM) was much lower than the World Health Organization guideline (31.5 μM) as the maximum allowable copper concentration in drinking water. In addition, 1-Cu^2 + complex could be used to detect cyanide by showing a color change from yellow to colorless, indicating the recovery of 1 from 1-Cu^2 +. Furthermore, the sensing mechanism of 1 for Cu^2 + was supported by theoretical calculations.
