Selective and sensitive ratiometric detection of Hg(II) ions using a simple amino acid based sensor.

Selective and sensitive ratiometric detection of Hg(II) ions using a simple amino acid based sensor. Synthesis of a novel pyrene derivative sensor (Py-Met) based on amino acid and its fluorescent behavior for Hg(II) in water was investigated. Upon Hg(II) binding, the Py-Met-bearing sulfonamide group exhibited a considerable excimer emission at 480 nm along with a decrease of monomer emission at 383 nm. Py-Met allows a selective and sensitive ratiometric detection of Hg(II) without any interference from other metal ions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Organic Letters Pubmed
