Synthesis of triazolyl anthracene as a selective fluorescent chemosensor for the Cu(II) ion

The Cu(I)-catalyzed azicle-alkyne cycloaddition reaction (CuAAC) has been used to synthesize ail anthracene-based fluorescent compound that undergoes strong fluorescence quenching in the presence of Cu(II). Fluorescence studies indicate that the compound forms a 1:1 complex and can be used to quantitatively determine micromolar concentrations of Cu(II) in aqueous solution. (C) 2008 Elsevier Ltd.
