Patent number: 7964721Abstract: A mercury selective fluorescent chemosensor for detecting mercury ions by a compound represented by formula 1 and a novel fluorescent sensitive compound prepared by introducing two aminopyrene functions as a fluorescent sensitive moiety into a binding site of the compound of formula 1 is used for selectively detecting mercury ions are provided. The mercury selective fluorescent sensitive chemosensor is a switch type chemosensor having ON-OFF-type Hg2+-selective fluorescence quenching behavior and is not affected by other coexistent metal ions. Changes in fluorescence of the compounds of formula 1 were analyzed by ratiometric approach using monomer and excimer emissions of the pyrene fluorophore to selectively signal the concentration of mercury ions. The chemosensor can detect mercury ions in a micromolar unit even in a solution including an excess of water. Accordingly, the mercury selective fluorescent chemosensor for detecting mercury ions can be used effectively in environmental and medical applications.Type: GrantFiled: October 9, 2007Date of Patent: June 21, 2011Assignee: Chung-Ang University Industry-Academy Cooperation FoundationInventors: Suk-Kyu Chang, Jun Soo Kim, Myung Gil Choi, Ki Cheol Song, Sangdoo Ahn, Kyoung Tai No
