英文摘要	A highly selective assay method has been developed to detect mercury (ii) (hg(2+)) ions using cationic conjugated polymer (ccp). the transduction mechanism is based on a hg(2+) promoted reaction. in the absence of hg(2+) ions, the ccp can form the complex with an anionic 1,3-dithiole-2-thione derivative through electrostatic interactions. the fluorescence of ccp is efficiently quenched by 1,3-dithiole-2-thione derivative via an electron transfer process. upon adding hg(2+) ions, the transformation of 1,3-dithiole-2-thione into 1,3-dithiole-2-one inhibits the quenching, and the fluorescence of ccp is recovered. distinguishing aspects of this assay include the signal amplification of ccps and a specific hg(2+) promoted reaction. by triggering the change in the emission intensity of ccp, it is possible to detect hg(2+) ions in aqueous solution.
