✦ Synopsis


A coumarin-based alkyne was developed as a fluorescent chemodosimeter for the selective detection of mercuric ion. It showed a high selectivity and sensitivity to mercury(II) ion over other metal ions in water.

## Abstract 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‐

A coumarin-based dithiane (1) was synthesized for the selective detection of Hg 2+ with respect to dual chromo-and fluorogenic changing events in an aqueous solution by the mercury-promoted transformation of a dithiane group into an aldehyde functional unit. The Hg 2+ -selective response of the chem
