A Novel Sensitive Fluorescent Coumarin-Based Chemosensor for Detection of Copper Ion

Ahmadreza Bekhradnia and Zahra Ghanbarimasir

A sensitive fluorescent chemosensor was developed for detecting CuII through microwave irradiation by using diethylamino-3-carboxamide coumarin. This receptor was employed as fluorescent probe for CuII with selectivity over other cations in aqueous solution. The fluorescence intensity quenched when 7-diethylamino-N-[2-(dimethylamino) ethyl]-2-oxo-2H-chromene-3-carboxamide (3) used as a receptor in the presence of very low concentration of CuII with an excitation at 360 nm.
