The environmental pollution has become a serious issue because the pollutants can cause permanent damage to the DNA, nervous system, and circulating system, resulting in various incurable diseases, such as organ failure, malformation, angiocardiopathy, and cancer. The effective detection of environmental pollutants is urgently needed to keep them far away from daily life. Among the reported pollutant sensors, luminescent metal–organic frameworks (LMOFs) with tunable structures have attracted remarkable attention to detect the pollutants because of their excellent selectivity, sensitivity, and recyclability. Although lots of metal–organic framework (MOF)‐based luminescent sensors have been summarized and discussed in previous reviews, the detection of environmental pollutants, especially radioactive ions and heavy metal ions, still have not been systematically presented. Here, the sensing mechanisms and construction principles of luminescent MOFs are discussed, and the state‐of‐the‐art MOF‐based luminescent sensors of environmental pollutants, including pesticides, antibiotics, explosives, VOCs, toxic gas, toxic small molecules, radioactive ions, and heavy metal ions are highlighted. This comprehensive review may further guide the development of luminescent MOFs and promote their practical applications for sensing environmental pollutants.

“…In the concentration range of 0-10 M, a correlation coefficient of Cd 2+ , Pb 2+ , Cu 2+ and Hg 2+ were 0.991, 0.9868, 0.989, 0.997, respectively with DL of 4.4 × 10 −8 mol L −1 for Cd 2+ , 4.8 × 10 −8 mol L −1 for Pb 2+ , 1.1 × 10 −8 mol L −1 for Cu 2+ , and 8.8 10 −9 mol L −1 for Hg 2+ [240]. Ionic luminescent metal-organic framework (ILMOF) is a new LMOF composed by a charged hybrid material of atoms and organic ligand which contains advantages electrification and intrinsic properties of MOF [241][242][243]. Based on the higher affinity of Hg 2+ to the nitrogen atoms, Wan et al (2018) selected [2, 2 :6 , 2 -Terpyridine]-4, 4 , 4tricarboxylic acid (TPTC) to design a MOF with organic ligand which contained multiple nitrogen atoms (N) for Hg 2+ detection.…”

Food contains a variety of poisonous and harmful substances that have an impact on human health. Therefore, food safety is a worldwide public concern. Food detection approaches must ensure the safety of food at every step of the food supply chain by monitoring and evaluating all hazards from every single step of food production. Therefore, early detection and determination of trace-level contaminants in food are one of the most crucial measures for ensuring food safety and safeguarding consumers’ health. In recent years, various methods have been introduced for food safety analysis, including classical methods and biomolecules-based sensing methods. However, most of these methods are laboratory-dependent, time-consuming, costly, and require well-trained technicians. To overcome such problems, developing rapid, simple, accurate, low-cost, and portable food sensing techniques is essential. Metal-organic frameworks (MOFs), a type of porous materials that present high porosity, abundant functional groups, and tunable physical and chemical properties, demonstrates promise in large-number applications. In this regard, MOF-based sensing techniques provide a novel approach in rapid and efficient sensing of pathogenic bacteria, heavy metals, food illegal additives, toxins, persistent organic pollutants (POPs), veterinary drugs, and pesticide residues. This review focused on the rapid screening of MOF-based sensors for food safety analysis. Challenges and future perspectives of MOF-based sensors were discussed. MOF-based sensing techniques would be useful tools for food safety evaluation owing to their portability, affordability, reliability, sensibility, and stability. The present review focused on research published up to 7 years ago. We believe that this work will help readers understand the effects of food hazard exposure, the effects on humans, and the use of MOFs in the detection and sensing of food hazards.

“…[105] Wan and coworkers have synthesized a novel Zn-based anionic MOF Zn-TPTC as a selective and sensitive sensor for detecting low levels of Hg 2+ with detection limits as low as 3.67 nM. [106] Their experiments showed that Zn-TPTC could exclude the interference of other ions, which could be attributed to the effective pore size, anionic framework, and multiple N sites in ligand, thus providing new ideas for the selection and design of MOF for detection applications.

Metal-organic frameworks (MOFs) are of great interest to researchers in chemistry and material science due to their various chemical and physical properties, which include high surface area, augmented adsorption/desorption kinetics, biocompatibility, and functional tunability. The structurally diverse 1-D, 2-D, and 3-D metalorganic frameworks have found applications in chemical sensing and several other fields, such as energy applications, biomedicine, and catalysis. In this review article, we address recent research advances in the use of metal-organic-framework-based nanocomposite materials as luminescent sensors for detecting various metal ions in aqueous biological and environmental samples.
