Abstract
- A novel Cu2+-specific colorimetric hydrazone sensor 1 was designed and developed. The color of 1 changes from colorless to pink on addition of 10.0 μM Cu2+ in aqueous buffer solution, which can be detected by the naked eye. The analytical detection limit for Cu2+ by the naked eye is as low as 2.0 μM. The stoichiometry for 1 and Cu2+ in complex is 2:1 in aqueous solution.
