“…which leave toxic residues in waterbodies [10–12] . For real‐time wastewater remediation, identification and selective recognition of contaminants are regarded as the preliminary step which holds decisive significance [13–16] . At the same time, removal or degradation of aquatic contaminants are considered as the ultimate solution toward water pollutant detoxification and purification [17–19] .…”

Water pollution and crisis of freshwater is one of the most alarming concern globally, which threatens the development and survival of living beings. Recycling of contaminated water has been the prime demand of 21st century as the area of contamination in natural waterbodies increasing rapidly worldwide. Detoxification and purification of wastewater via adsorptive removal technology has been proven to be more efficient because of it's simplicity, lesser complexity and cost‐effectiveness. As the most rapid‐growing division of coordination chemistry, porous coordination polymers (PCPs) or metal−organic frameworks (MOFs) with the liberty of crafting tailorable porous architecture and presence of numerous functional sites have become quintessential for recognition and sequestration of water pollutants. This personal account intends to highlight our recent contributions in the field of sensing and sequestration of toxic aquatic inorganic pollutants by functionalized water stable MOFs.

“…It should also be stable with sufficient functional groups, which could efficiently interact with the target HMs. Different fluorophores including small organic dyes, metal-ligand complexes, metal-organic frameworks (MOFs) [8,9], semiconductors (NCs) and metal nanoclusters [10], silica nanoparticles (NPs) [11], and zerodimensional carbon dots (CDs) [12] could be designed separately or combined as HMs sensing platforms. Among them, small molecular organic dyes such as rhodamine, fluorescein, cyanine, and coumarin are the most chosen in traditional fluorophore and broadly used.…”

Heavy metal (HM) pollution is a major global concern. Carbon dots (CDs) have demonstrated unique properties as sensing platforms for HMs detection. This review summarizes the progress made in recent years in fluorescence methods to determine HMs and their species using CDs. First, the strategies to synthesize and purify CDs are reviewed. The photoluminescence principles of CDs and their sensing mechanisms as HMs sensors are then summarized. The binding strategies between CDs and HMs are proposed to provide salient principles to design desirable CD-based HMs sensors. The preparation and merits of “turn-on” and ratiometric CDs for HMs detection with higher accuracy are discussed compared with commonly used “turn-off” sensors. Subsequently, the progress on detecting single HM ions, multi-HMs, and different metal species in solution, and the development of gel/solid-state sensor platforms such as paper-based devices, sensor arrays, hydrogels, polymer films, and ion-imprinted polymers are critically accessed. Furthermore, the advances in the cell, bacterial, plant, and animal bioimaging of HMs with CDs as promising bioimaging reagents are presented. Finally, the challenges and prospects of CDs as HMs sensors in future investigations are discussed.

“…The rational design and construction of these compositions in LMOFs can make the most of their advantages to achieve superior detection performance. Although a large number of reviews have summarized the luminescence sensing applications of LMOFs, [41][42][43] there is still no review in regards to the antibiotic detection by LMOFs. Therefore, we focus on providing an overview of LMOFs as luminescence sensors toward various antibiotics.…”
