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 binding, the Py-Met-bearing sulfonamide group exhibited considerable excimer emission at 480 nm along with decrease monomer 383 nm. Py-Met allows selective sensitive ratiometric detection without any interference from other metal ions.
