Highly Selective Visual Detection of Cu(II) Utilizing Intramolecular Hydrogen Bond-Stabilized Merocyanine in Aqueous Buffer Solution
摘要:
A Cu2+-specific colorimetric sensor 1, which is stabilized by an intramolecular hydrogen bonding, was designed and developed. The color of 1 changes from purple to blue on addition of 1.0 mu M 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 1.0 mu M. The stoichiometry for 1 and Cu2+ in complex is 2:1 in aqueous solution.
