✦ Synopsis

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 chemodosimeter was clearly observed in aqueous buffer as well as in human blood plasma medium.

## 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‐

## Abstract A highly selective fluorescence sensor was developed for Hg(II) ion detection in aqueous solutions based on the selective binding of Hg(II) ions with a pair of thymine‐thymine mismatch. The sensor consists of two DNA probes functionalized with a fluorophore (fluorescein, F) and a quench

Contamination with heavy metal ions may have severe effects on human health and the environment. Mercury contamination is widespread and arises from a variety of natural sources, such as oceanic and volcanic emissions, [1] as well as anthropogenic sources, [2] such as gold mining and the combustion
