Selective Recognition of Hg²⁺ ion in Water by a Functionalized Metal–Organic Framework (MOF) Based Chemodosimeter

A metal–organic framework (MOF)-based highly selective and sensitive probe ( [email protected] ) for the detection of Hg(II) ion has been developed. To the best our knowledge, this is the foremost example of a chemodosimeter-based approach to sense Hg(II) ion using a MOF-based probe. The chemical stability of [email protected] renders the sensitive detection of Hg 2+ ion in an aqueous phase. [email protected] has been found to be selective for Hg(II) ions even in the presence of other metal ions.
