“…Nitrophenol compounds have always been a typical pollutant that endangers the environment, and this class of compounds is very toxic and difficult to degrade because of the structure of their benzene ring and the presence of nitro groups, causing great harm to the environment. − So, it is important for researchers to detect nitrophenol compounds using EtOH suspensions of complexes 2 by adding nitrophenol compounds (Figure S60) in EtOH solvents (10 –2 mol/L), including o-nitrophenol (ONP), p -nitrophenol (PNP), 2,4-dinitrophenol (DNP), and 2,4,6-trinitrophenol (TNP). Complex 2 (2 mg) was dispersed in 2 mL of EtOH solvent, and all of the analytes (200 μL) exhibited different fluorescence quenching effects, as shown in Figure b and Table S13.…”

Stimuli-Responsive Naphthalenediimide Cd-MOFs Tuned by Different Aliphatic Dicarboxylic Acids with Extended Spacers

et al. 2022

A series of novel Cd metal−organic frameworks (MOFs) (1−9) with different extended spacers with seven kinds of the aliphatic dicarboxylic acids as secondary building linkers based on N,N′-di(4-pyridylacylamino)-1,4,5,8-naphthalenediimide (NDI-A) have been designed and synthesized by changing the volume ratio of solvents under solvothermal conditions. In addition, the secondary building linkers of aliphatic dicarboxylic acids have different spacer lengths, resulting in different structures of complexes 1−9. So, their packing structures are affected by the degree of distortion of the NDI-A ligand, the different aliphatic dicarboxylic acids ligands, and the hydrogen-bonding patterns. Complexes 1−9 showed stimuli-responsive emission tuned by different aliphatic dicarboxylic acids with extended length spacers under UV light irradiation, accompanied by the color change from light orange to dark brown, and achieved reversible photochromic under heating, which indicates that they could serve as secret erasable inks. Moreover, complexes 1−9 exhibited selective vaporchromic behavior to methylamine (MA), and the vaporchromic sample could be recovered after washing with MeOH. It is worth noting that the preparation of poly(vinyl alcohol) (PVA)-NDI-MOF films enables the photochromic and vaporchromic properties of complexes 1−9 to apply in practice. In addition, complexes 1−9 exhibited good fluorescence properties as sensing probes toward 2,4,6-trinitrophenol (TNP) with lower limits of detection. In short, this work provides a broad field to explore the creative NDI-MOF materials with photoactive and luminescent properties.

“…46 In 2016, Suresh and co-workers synthesized a 2D cadmium-based MOF for the detection of TNP with an LOD value of 62 ppb. 47 Recently, Sinha and co-workers synthesized a 2D MOF that detected the nitroaromatic explosive TNP with an LOD value of 2.75 × 10 −7 M. 48 Yang and co-workers reported a lanthanide-based 2D MOF that showed the detection of TNP with an LOD value of 4.13 × 10 −6 M. 49 Detection of these antibiotics and explosives by using our 2D material (ZCP) is comparatively more efficient in terms of LOD and versatility sensing mode than the 2D probes reported in the literature.…”

A fluorescent zinc-based two-dimensional (2D) coordination polymer, {[Zn(cis-CHA)(BPEP)0.5]•DMF}n (ZCP), has been synthesized using solvothermal reaction conditions. ZCP is characterized using singlecrystal X-ray diffraction, powder X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetric study, and elemental analysis. In waterdispersed medium, the framework (ZCP) detects antibiotics, such as nitrofurantoin (NFT) and nitrofurazone (NZF), as well as an organo-toxin aromatic compound, trinitrophenol (TNP). The limit of detection (LOD) values for NFT, NZF, and TNP are found to be 21.75, 24.31, and 13.47 ppb, respectively. Such sensing behavior is also apprehended by colorimetric response in solid and solution along with a strip paper method. After sensing of each and individual analytes, the sensor is recycled without losing its efficiency. Interestingly, the detection of these analytes by this sensor is also comprehended for real-field analysis with high accuracy and repeatability. The sensing behavior is strongly supported by profound experimental investigation, including the lifetime measurement, and the mechanism of sensing is well supported by theoretical calculations.
