| Abstract: | The dye chemosensor for mercury ion detection was designed, which was based on donor-acceptor intramolecular charge transfer system and the corresponding fluorescence changing property was successfully monitored. This new dye chemosensor was containing dimethylcarbamodithioate groups to coordinate Hg2+, which showed very effective sensing functions. But it showed no significant changes upon the addition of other metal ions such as Ca2+, Pb2+, Al3+, Ce2+, Ba2+, Ni2+, Cd2+, Zn2+, and Mg2+. |
