文摘

2-pyridyl quinoline based Cu2+ ion chemosensor has been developed. Binding of Cu2+ ions to chemosensor resulted into fluorescence quenching. This chemosensor enabled to detect Cu2+ ions with the naked eyes. Chemosensor-Cu2+ ion complexation could be reversed with EDTA making the probe reusable.
