“…Solvent recognition experiments showed that the color variations of this MOF could be distinctly observed with the naked eye when treated with ketone molecules, as shown in Figure 19 b. The possible induction mechanism can be attributed to the hydrogen bonding interaction between guest ketone molecules and μ 2 -bridged oxygen, which can lead to the deformation of the octahedral coordinated Mn 2+ center, as shown in Figure 19 c. Li et al developed an ultra-stable tetrazolium Cd-based MOF {[Cd 2 (μ 7 -L)(μ 3 -OH)(H 2 O) 2 ]·1.3H 2 O} n containing a new bi-functional ligand H 3 L (H 3 L = 4′-(1H-tetrazole-5)-biphenyl-2,3-dicarboxylic acid) under the solvo-thermal conditions [ 140 ]. Fluorescent characterization shows that this ultra-stable MOF allows highly sensitive real-time discrimination of acetylacetone with good reusability (high quenching efficiency K sv for acetylacetone: 2.5 × 10 5 M −1 ) and very low detection limit values (for acetylacetone: 35 μM).…”

Population growth and industrial development have exacerbated environmental pollution of both land and aquatic environments with toxic and harmful materials. Luminescence-based chemical sensors crafted for specific hazardous substances operate on host-guest interactions, leading to the detection of target molecules down to the nanomolar range. Particularly, the luminescence-based sensors constructed on the basis of metal-organic frameworks (MOFs) are of increasing interest, as they can not only compensate for the shortcomings of traditional detection techniques, but also can provide more sensitive detection for analytes. Recent years have seen MOFs-based fluorescent sensors show outstanding advantages in the field of hazardous substance identification and detection. Here, we critically discuss the application of MOFs for the detection of a broad scope of hazardous substances, including hazardous gases, heavy metal ions, radioactive ions, antibiotics, pesticides, nitro-explosives, and some harmful solvents as well as luminous and sensing mechanisms of MOF-based fluorescent sensors. The outlook and several crucial issues of this area are also discussed, with the expectation that it may help arouse widespread attention on exploring fluorescent MOFs (LMOFs) in potential sensing applications.

“…Exposing acac to the environment could result in pollution and pose a threat to human health, such as headache, nausea and vomiting after inhalation. 17 To date, many fluorescent sensors based on CPs or MOFs for acac have been reported, 17–32 while most of them display fluorescence quenching (turn-off effect), 17–29 and limited sensors exhibit fluorescence enhancement (turn-on effect) and shift. 30–32 Compared with the turn-off effect, the turn-on effect has higher sensitivity and is easier to identify, and the fluorescence shift has a noticeable change of colour, which could obviously distinguish targeted substances from other analytes.…”

The smart fluorescent hydrogels exhibiting tunable fluorescence have been used as biosensors, probes, light-emitting devices, and information storage and confidentiality. However, they usually show single stimuli responsiveness and possess weak mechanical properties, which limit their applications. Herein, we report a pyridine-dicarbohydrazone-based polyacrylate hydrogel (the As-prepared hydrogel and Eu-hydrogel) showing strong mechanical property, tunable fluorescence ability, and thermal and pH stimuli responsiveness. The As-prepared hydrogel is prepared by light-induced micellar copolymerization, and Eu-hydrogel is obtained after the formation of Eu3+-(pyridine-dicarbohydrazone) coordination. The As-prepared hydrogel could be made in large size (side length of 15 cm), exhibiting a tensile strength of 1.55 MPa and a fracture tensile strain of 800%. The fluorescence intensity of Eu-hydrogel is tunable by [Eu3+] (approaching 655% of the minimum state at [Eu3+] = 0.1 mol). It is demonstrated that Eu-hydrogels display force-induced fluorochromic response during stretching. The transmittance temperature of the As-prepared hydrogel ranges from 36 to 42 °C. Reversible Eu3+-(pyridine-dicarbohydrazone) coordination enables Eu-hydrogels to have excellent fatigue resistance. The pH stimuli responsiveness of the As-prepared hydrogel and Eu-hydrogel is triggered by switchable covalent hydrozone bonds. In terms of the shape-memory ability, the As-prepared hydrogel could be reconstructed by Eu3+ and Eu-hydrogel could be deformed by H+. This mechanically strong (pyridine-dicarbohydrazone)-based polyacrylate hydrogel with multistimuli responsive behaviors is promising to be used in information transmission, smart windows, load-bearing devices, energy-absorbing materials, and soft wearable devices.
