“…Furthermore, the sensor possessed good recyclability after washing with deionized water several times. [256] The MOF sensors for NACs involved different types of mechanisms and interactions, but the presence of Cd as the central metal ion resulted in electron transfer from the MOF to the LUMO orbital of the guest NACs as the mechanism, with electrostatic interactions causing dipoles to occur due to different electron densities (Figure 8d). [257] Furthermore, the interaction between a Ti(II)-MOF and TNP was readily observed by the naked eye, showing quenching of the fluorescence spectra.…”

The success of MOFs has driven their development as a new tool for sensing analytes including toxic chemicals. [19][20][21] The MOF sensors can be applied in both environmental and biological systems. [22] The MOF sensor field has been established with the development of sensors for different metal ions, anions, and molecules. [23,24] The potential application of MOF sensors to the detection of heavy metal ions, toxic anions, and other hazardous species is of great interest. [25,26] Specifically, luminescence technology has allowed the roles of various MOF sites in analyte capture to be easily studied. [27][28][29] The precise use of MOFs is potentially a good tool for analyte detection. Furthermore, MOFs have been established as potential materials for selective, fast, and portable tools for sensing toxic chemicals, with the advantage of light-emitting properties. [30,31] Interestingly, these sensing models can operate in water and are pH stable with high efficiency. [32] Furthermore, MOFs are wellknown materials for the degradation of toxic chemicals. [33,34] Several reports have been published on MOF sensors for toxicant chemicals, such as metal ions, anions, organic solvents, pesticides, nitroaromatic compounds (NACs), chemical warfare agents, [35] and others. [36][37][38] Some reviews have summarized applications of MOFs in sensing and detection probes for ions and volatile organic compounds, [39] and MOF sensors in pesticide detection and absorption with their classification. [40] Others have summarized and analyzed interactions between hazardous compound adsorbates and MOFs. [41,42] The stability and applications of MOFs have been summarized by the research groups of Ding and coworkers. [43] Pehlivan and et al. summarized the role of fluorescence resonance energy transfer in elucidating molecular interactions utilized in biosensing tools. [44,45] Besides luminescence sensing, the reviewers summarized the progress of MOFs relevance in the various area including environment and medical science. [46] Recently, Liu and coworkers summarized the progress of MOFs and discussed the remaining challenges in drug delivery, [47] Garcia and coworkers studied and compared the MOFs as photocatalysts with common inorganic photocatalysts, [48] and Manos and coworkers studied and summarized MOFs challenges and prospects for ion-exchange and sorption applications. [49] Despite these meaningful reviews, the factors responsible for signal changes, mechanisms, and limits of detection have Mechanistic studies of materials able to detect hazardous and toxic chemicals, such as common organic solvents, pesticides, and nitroaromatic compounds (NACs), are critically important owing to the threat they pose to humans and the environment. Recently, porous luminescent metal-organic frameworks (MOFs) with multifunctional sites, high surface areas, and structural tunability have emerged as sensory devices for the detection of hazardous and toxic chemicals. Herein, recent progress regarding the mechanistic behavior of MOF sensors in the det...

“…To the best of our knowledge, the Ksv value obtained in this work is larger than Ksv of the sensors previously applied to detect 4-NP (Table I). [27][28][29][30][31][32] Next, the fluorescence quenching behavior of poly(NIPAM-AM-BMPS) in the presence of various metal ions (1.0 mol m -3 , λ ex = 295 nm), such as Na + , Mg 2+ , Li + , Ca 2+ , Ag + , Cr 3+ , Zn 2+ , Cd 2+ , Ni 2+ , Cu 2+ , Co 2+ , Mn 2+ , Ba 2+ , Al 3+ and Fe 3+ , was studied. Only Fe 3+ caused an obvious fluorescence quenching as shown in Fig.…”

In this communication, a novel diphenyl sulfone-functionalized water-soluble polymer was successfully synthesized through a facile hydrothermal synthesis route and then characterized by FT-IR, UV-vis, 1H-NMR and 13C-NMR spectra. Fluorescence quenching experiments revealed that the fluorescence intensities of the resulted diphenyl sulfone-functionalized polymer were linear with the concentrations of Fe3+ ions and 4-nitrophenol (4-NP) in the concentration range of (5.0?24.9)?10-8 and (5.0?50.0)?10-7mol dm-3, with the detection limit of 2.8?10-8 and 2.2?10-7 mol dm-3, respectively. These results create opportunities for developing novel chemosensors by introducing selective fluorescent group into the polymermaterials.

“…4,4′-Bipyridine is a type of ligand that is often used in the synthesis to obtain coordination polymers. Such complexes exhibit very unique properties like photoluminescence or photochromism [ 25 , 26 , 27 , 28 ], biological [ 29 , 30 ] and magnetic properties [ 26 , 31 ], or the ability to detect or absorb harmful substances [ 32 , 33 , 34 , 35 ]. In this paper, we present synthesis, thermal properties, and crystal structures of two 4,4′-bipyridine coordination polymers with lanthanum (III) and samarium (III) dibromoacetates.…”

Two novel mixed ligand complexes with general formula [M2(4,4′-bpy)1.5(CBr2HCOO)6(H2O)2]n (where 4,4′-bpy = 4,4′-bipyridine) were synthesized. Thermal analysis was used to describe a solid intermediate and final products of thermolysis. A coupled TG-MS system was used to monitor principal volatile fragments evolved during pyrolysis. Crystal structures of the complexes were determined. Cationic dinuclear M2 (M(III) = La, Sm) coordination cores were obtained. Both crystal structures are isostructural. Single crystal X-ray diffraction analysis revealed that investigated structures of 1D coordination polymers assembled in ladder-like systems. The central atom replacement resulted in unit cell identity parameter П = 0.0091. Additionally, the isostructurality of the reported La(III) and Sm(III) complexes was revealed using Hirshfeld Surface analysis supported by Enrichment Ratio calculations.
