- Novel chromophore GZP1 with D-π-A structure was designed and prepared for its application as a sensor for the recognition of Cu2+ ions in polluted water. Reaction of aldimine condensation was used to synthesize chromophore GZP1. Its chemical structure of was characterized by mass spectrum, nuclear magnetic resonance spectroscopy and ultraviolet-visible absorption spectrum. Cu2+ ions were recognized via fluorescence spectra. Chromophore GZP1 showed specific detection ability of Cu2+. 14 other metal ions were used as reference. The detection limit was estimated to be 0.06 μmol/dm3 in aqueous solution, which was significantly lower than the typical concentration of blood Cu2+ in normal individuals and the limit of copper(II) in drinking water.
