Luminescent metal-organic framework (LMOF), as a class of metal-organic framework (MOF), is a novel class of porous material formed from metal ion and bridging organic ligands. Its unique structural and chemical properties have enabled us to reliably detect mercury ions, one of the most toxic contaminants in the environment. Additionally, the luminescence of LMOFs has made the detection process ever more convenient. In this paper, we pay attention on the change of luminescent intensity of these materials in the presence of Hg 2 +. We focus on several key publications in this area, including examples of LMOFs with excellent performance on Hg 2 + detection, and we expect this review will provide new guidelines for Hg 2 +sensor engineering.
