  • Title: Novel coumarin-based fluorescent probe for selective detection of Cu(II).
    Author: Bekhradnia A, Domehri E, Khosravi M.
    Journal: Spectrochim Acta A Mol Biomol Spectrosc; 2016 Jan 05; 152():18-22. PubMed ID: 26186393.
    Abstract:
    We report an efficient and convenient method for preparing nitro-3-carboxamide coumarin derivatives, proposed as novel fluorescent chemosensor, through microwave irradiation. This compound can be used as fluorescent probe for Cu(2+) with selectivity over other metal ions in aqueous solution. The fluorescence of 6-nitro-N-[2-(dimethylamino)ethyl]-2-oxo-2H-chromene-3-carboxamide(3) is the highest in the presence of Cu(2+), with stronger excitation at λ=320nm than for the other cations tested.
