Copper ions are essential for human health but excessive intake can cause severe health issues. Fluorescence detection of copper ions typically relies on small-molecule probes, which suffer from slow reaction kinetics and low sensitivity at low concentrations. In contrast, metal–organic framework (MOF)-based fluorescent probes offer rapid response time and structural tunability, but often have low fluorescence quantum yields. This study presents a novel detection strategy using a functionalized zirconium-based MOF with naphthalimide as the luminescent moiety. A post-synthetic modification (PSM) strategy was used to graft Schiff base recognition units onto the MOF surface, which undergo specific coordination hydrolysis with copper ions, triggering fluorescence quenching. The resulting probe achieves a high fluorescence quantum yield (Φ = 36.88%) and ultra-fast response (<5 s), with a low detection limit (LOD = 0.167 µM) and excellent selectivity. The probe's broad linear detection range was successfully applied to real water samples. X-ray photoelectron spectroscopy (XPS), Gaussian theory calculations, and UV-visible absorption spectroscopy confirmed that the fluorescence quenching is mainly due to suppression of intramolecular charge transfer (ICT). This modular approach can be adapted for the rapid, sensitive detection of various pollutants using MOF-based probes.

Multimodal tumor therapies suffer from poor spatial co-localization, asynchronous activation, and weak cross-modal reinforcement, leading to limited therapeutic efficiency. Here, we report a photoelectric therapy needle (PTN) system that achieves in situ synchronous electrothermal-photodynamic therapy (synchronous ETT-PDT) and amplifies chemotherapeutic efficacy through hierarchical cross-modal and cross-component reinforcement. The PTN integrates optical fibers and heating wires within a single hollow needle, enabling precise, spatiotemporally synchronized activation under ultralow energy (0.2 V, 0.1 W cm −2 ). We further designed hyaluronic acid-modified MOF@infinite coordination polymer nanocomposites (HA-MOF@ICP NCPs) co-loaded with ICG, SN38, and AQ4N for sequential release. This structure allows PDT-induced hypoxia to activate AQ4N, while ETT enhances SN38 cytotoxicity, establishing a bidirectional ETT↔PDT reinforcement and multi-level drug synergy. In vivo, PTN-NCPs achieved complete eradication of large tumors (≈300 mm 3 ) within 21 days using one-tenth conventional PDT energy and minimal drug doses (1/2.5 AQ4N, 1/12.5 SN38), with no recurrence over 60 days. Four parameters of toxicity, energy, dosage and therapeutic effect were selected and normalized to assess the cost-effective degree of our mutually reinforcing strategy. Compared with the results of prior trimodal strategies, our mutually reinforcing strategy had the largest cost-effective degree value (1.6–10.9 times high), achieving high cost-effective tumor comprehensive therapeutic outcomes.

It is a great challenge to develop the cathode materials with high efficiency, long life and low-cost for lithium-sulfur batteries. In this paper, we design a simple hydrothermal method to synthesize MoS 2 wrapped the MOFs-derived N-doped carbon nanorods as an effective sulfur host to improve the electrochemical performance of lithium-sulfur batteries. In the hydrothermal process, the cubic zeolitic imidazolate framework-67 (ZIF67) particles are connected together to form nanorods , and MoS 2 nanosheets are wrapped on the surface of the nanorods. In this composite, the carbon nanorods derived from ZIF67 is the main host for S-loading, while N-doping can change the hybrid orbital form of carbon and significantly improve the chemical adsorption of polysulfide . The elemental cobalt and cobalt oxide derived from ZIF67 can improve the electronic conductivity and polarity of the composite. And MoS 2 coating layer can provide more active sites, accelerate the sulfur redox reactions and effectively restrain the shuttle effect. The synergetic effects of above-mentioned factors make the MoS 2 @CZIF67/S composite cathode material shows excellent electrochemical performance. The composite shows high reversible specific capacities of 1391.9 and 806.1 mAh g −1 at 0.1C and 1C rate, respectively, and exhibits a capacity retention of 70.5% after 400 cycles at 1C rate.

The in situ formation of interconnected carbon nanotubes (CNTs) networks on the surfaces of metal-organic framework (MOF) derivatives is an efficient method for rationally constructing heterogeneous interfaces and developing high-performance electromagnetic wave absorption materials. A series of Co x Ni y @C composite absorbers with abundant CNTs on their surfaces prepared by pyrolyzing MOF precursors in an Ar atmosphere is reported in this study. The S-3 composite absorber had a distinct structural morphology, and optimal wave absorption performance was obtained when the final pyrolysis temperature was 800 °C. At matched thicknesses of 2.0 mm and 3.5 mm, an effective absorption bandwidth (EAB) of 4.5 GHz and a minimum reflection loss (RL min ) of −43.5 dB were achieved when the absorber filling ratio was 15 wt%. This strategy and the results reported in this study are anticipated to encourage future studies into the controlled growth of metal-catalyzed CNTs and inspire new ideas for designing and preparing enhanced microwave absorber materials at the micro-nano scale.

Metal-organic frameworks (MOFs) are considered one of the promising adsorbents for CH 4 /N 2 separation. However, MOFs commercialization is a big challenge since their synthetic materials are expensive and not environmentally friendly. Herein, the dealumination solution obtained from coal fly ash (CFA) using sulfuric acid as an extracting agent through direct leaching and roasting technologies was applied as metal feedstock to prepare CFAx-FumMOF-y and compared to aluminum fumarate MOF (Al-FumMOF) in morphology, surface area, micropore volume, and CH 4 /N 2 selective separation. The results indicated that CFAx-FumMOF-y exhibited closely similar surface area (1164.94–1073.08 m 2 /g) and micropore volume (0.40–0.36 cm 3 /g) to Al-FumMOF (1287.55 m 2 /g, 0.42 cm 3 /g), even there were no detectable differences in CH 4 uptakes (CFAx-FumMOF-y, 21.93–20.69 cm 3 /g; Al-FumMOF, 22.13 cm 3 /g) at 298 K and 1.0 bar, suggesting that the impurity metal species in dealumination solution hardly affect textural properties and gas uptakes. Moreover, the isosteric heat of adsorption (Q st ) and IAST CH 4 /N 2 selectivity of CFAs-FumMOF-1 (19.25–17.84 kJ/mol) and CFAb-FumMOF-1 (18.83–18.64 kJ/mol) were slightly superior to Al-FumMOF (17.83.64–16.86 kJ/mol, 4.87), suggesting that CFAx-FumMOF-1 played an identical role as Al-FumMOF in gases separation. The cyclic regeneration experiments and binary breakthrough tests further confirmed that CFAx-FumMOF-y was feasible for practical application. This study provides a new perspective for reducing the production cost of MOFs as well as realizing high-value utilization of CFA.

Metal–organic frameworks (MOFs) with a high surface area and excellent stability are potential candidates for uranium (U) adsorption. Amidoxime (AO) is the most widely used functional group to extract U, which is usually introduced into MOFs by two-step post-synthetic methods (PSMs). Herein, MOF UiO-66-NH-(AO) was obtained by a one-step PSM with amidoximation from UiO-66-NH-(CN), which was synthesized by a new organic ligand of 2-cyano-terephthalic acid and whose morphology was octahedron and could be well controlled with the new ligand. The one-step PSM can greatly maintain the octahedron of the MOFs. What is more, UiO-66-NH-(AO) showed good adsorption performance for U, the adsorption equilibrium was obtained within 1500 min, and the adsorption capacity of U was calculated to be 134.1 mg/g according to the Langmuir model. It also had excellent selectivity for U in the presence of high concentrations of vanadium (V), ferrum (Fe), magnesium (Mg), calcium (Ca), and zirconium (Zr). The adsorption capacity of U in natural seawater was determined to be 5.2 mg/g within 8 days. The recyclability of UiO-66-NH-(AO) in simulated seawater was demonstrated for at least four adsorption/desorption cycles. The binding mechanism was investigated by the extended X-ray absorption fine structure spectroscopy, revealing that U binding occurs in a fashion η2 motif. This study provides a reliable idea for the modification of MOFs and the potential for MOF-based materials to extract U from seawater.

Naringin (NRG) is a bioactive substance with important pharmaceutical and industrial value. However, the major challenges in the separation of NRG arise from the complexity and low concentration of crude extracts. In this work, by integrating the advantages of magnetic separation, MOFs@COFs composite materials, and surface molecular imprinting strategy, a new kind of magnetic MOF@COF-based boronate-affinity molecular imprinted adsorbent (NH2-MIL-68-Fe3O4@COFs@BA-MIPs) was constructed. Magnetic NH2-MIL-68 substrates were prepared by the solvothermal method, aldehyde-functionalized by surface modification with 2,4,6-triformylphloroglucinol (Tp). Then, a covalent organic framework shell was grown on the surface of substrates via the Schiff base reaction. Finally, a boronate-affinity imprinted polymer was prepared via surface-initiated atom transfer radical polymerization (SI-ATRP). The as-prepared adsorbent features rapid magnetic separation. In addition, the high-density boronate-imprinted recognition sites and porous structure endow the material with a fast adsorption rate (reaching equilibrium about 60 min), a high adsorption capacity (57.29 μmol g–1), and good retention performance (92.79%) after six adsorption–desorption cycles at 308 K under pH 8.0. Moreover, the extraction rate of crude NRG by NH2-MIL-68-Fe3O4@COFs@BA-MIPs reached 93.61%. This study provides a design strategy for constructing NRG adsorbents with rapid magnetic response and has important application value in the specific separation and purification of flavonoids.

Carboxylated modified cotton fabrics via a diazotization reaction followed by in-situ growth of Co/Zn bimetallic MOFs. • The coating surface achieved a separation efficiency of over 99% for heavy-density oil/water mixtures and over 97% for light-density oil/water mixtures. • Degradation of most dyes and antibiotics by light and PMS activation synergistic catalysis. • Active sites of molecular structure and ecotoxicity of degradation products were investigated by DFT and T.E.S.T., respectively. In this paper, a diazotization reaction was first used to introduce carboxyl groups on the surface of cotton fabrics, and then Co/Zn bimetallic metal organic frameworks (MOFs)-based ZIF-67/8 were in-situ grown on the carboxylated cotton fabrics. Subsequently, 3-mercaptopropyltriethoxysilane (MPTES) formed a covalent bond with 10-undecenoic acid (UA) through a photo-initiated thiol-ene click reaction, and after the addition of polymethylhydrosiloxane (PMHS), it formed a strong covalent bond with the hydroxyl groups on cotton fibers through a hydrolysis condensation reaction. Hence, a polymer-functionalized Co/Zn bimetallic MOFs-based superwetting cotton fabric coating surface (PMHS/UA/ZIF-67/8-CF) was obtained. Polymer-functionalized MOFs coatings, exhibiting wettability reversible conversion capability, are favorable for the separation of different types of oil/water mixtures and maintaining excellent separation performance. Furthermore, the Co/Zn bimetallic MOFs exhibited efficient degradation by a dual-path mechanism through synergistic light-driven charge separation and PMS (peroxymonosulfate) activation. It exhibited excellent catalytic degradation properties for dyes such as phenothiazines, xanthenes, and azo compounds, as well as tetracene derivative antibiotics. In addition, the active sites of the molecular structure and the catalytic degradation pathways were investigated using density functional theory (DFT) calculations and liquid chromatography-mass spectrometry (LC-MS) analysis, respectively. Ultimately, the toxicity of methylene blue (MB) and its degradation products was evaluated using the toxicity estimation software tool (T.E.S.T.). This work presents a promising research strategy for environmental wastewater treatment, demonstrating the potential of functional coatings with reversible conversion wettability and properties for degrading organic pollutants.

A Janus magnetic MOFs/PEN-MXene film with stepwise impedance matching was fabricated. • The composite achieves an EMI SE of 45.5 dB via synergistic magnetic/dielectric loss. • The film enables rapid electro/photo-thermal response, reaching 121.8 °C (6 V) and 114.2 °C (250 mW/cm 2 ). • Strong interfacial interactions ensure high mechanical strength (77.8 MPa) and thermal stability (508 °C). To address the challenge of integrating high shielding effectiveness, efficient thermal management, and environmental stability in advanced materials for low-altitude aerial vehicles, a novel Janus structured composite film is constructed by integrating magnetic metal–organic frameworks (MOFs) and MXene into a high-performance Poly(arylene ether nitrile) (PEN) matrix via polar coordination and molecular chain bridging. The asymmetric Janus architecture establishes a stepwise impedance gradient, while synergistic magnetic loss from the MOFs together with ohmic dissipation and interfacial polarization from the conductive MXene ensures efficient electromagnetic attenuation. The continuous MXene network further provides surface electrons for thermal management, enabling active response under low-temperature environments. Benefiting from the synergistic effects of the components and the Janus design, the Co-MOF@Fe 3 O 4 -PEN/MXene (CoFeP/M) film demonstrates excellent EMI shielding effectiveness of 45.5 dB in the X-band, accompanied by fast-response thermal management. Under 6 V and 250 mW/cm 2 light power density, the surface temperature reaches 121.8 °C and 114.2 °C, respectively. Simultaneously, strong interfacial interaction between PEN and Co-MOF@Fe 3 O 4 promote mechanical stability, ensuring structural integrity and thermal stability (77.8 MPa and 508 °C). This work introduces a novel strategy for designing multifunctional Janus composites with gradient interfaces and strong synergistic effects, advancing next-generation materials for low-altitude aerial vehicles.

Quantitative detection of Salmonella typhimurium is of vital importance for promoting food safety monitoring and control. This study successfully developed a 3D-printed microchannel device that integrates cleaning and detection functions, enabling sensitive and semi-automatization colorimetric detection of Salmonella typhimurium . Firstly, the magnetic beads modified monoclonal antibody (MBs-Anti), Salmonella typhimurium and PtRu@ZrFe-MOFs@Apt nanozymes were successively added to the centrifuge tube to facilitate the formation of the MBs-Anti- Salmonella typhimurium -PtRu@ZrFe-MOFs@Apt sandwich complex. Then, the above incubated mixture was injected into the reaction tank of the microchannel device and washed with PBS containing hydrogen peroxide to separate the sandwich complex from the impurities in the sample solution. Subsequently, the TMB substrate solution was added to facilitate the catalytic oxidation of the sandwich complex, thereby forming the blue oxidized TMB product. The RGB image of the blue product was captured using a portable smartphone device, and the colorimetric signal of the image was analyzed to determine the concentration of Salmonella typhimurium . The microchannel device can detect Salmonella typhimurium within a concentration range 10 1 to 10 6 CFU/mL within 75 min, with a detection limit of 3.3 CFU/mL. It is worth noting that the 3D-printed microchannel device constructed has good universality. By replacing the corresponding antibodies, aptamers and other biological recognition elements, it can be extended to the detection of other pathogenic bacteria.

A facile “layer by layer” strategy was used to fabricate core-shell-structured magnetic molecularly imprinted fluorescence encoded microspheres, by integrating a Fe 3 O 4 magnetic core, a ZIF-8 inner-layer, an in-situ grown imprinting shell, and the final encoded quantum dots. This architectural design not only offered the capability of rapid magnetic separation, specific recognition, and sensitive fluorescence response, but also effectively avoided direct contact between the magnetic core and quantum dots, resulting in excellent fluorescence performance. Considering the strong magnetic responsiveness, the obtained microspheres were further employed into magnetic solid phase extraction to selectively capture tetracycline for fluorescence analysis. Under the optimum conditions, the sensor achieved ultra-rapid detection time with 1 min, and exhibited a closely linear relationship (R 2 = 0.9941) in the range 3–200 µg L − 1 with a method detection limit of 3 µg L − 1 . The spiked recoveries ranged from 83.2% to 112.8% in milk, egg, honey, and pork samples, with RSD value < 7.63%. This work offers an ultra-rapid fluorescence analytical strategy with high accuracy, reliability, and anti-interference capability, and could be considered as an ideal alternative for the rapid detection of various trace contaminants.

Electromagnetic (EM) wave absorbing materials have been extensively applied in the electronic devices and wireless communication to solve the increasingly serious problems of electromagnetic pollution and radiation. In this work, Fe-MOFs/biomass cotton derived Fe@nanoporous carbon@carbon fiber (Fe@NPC@CF) composites were successfully obtained by means of in-situ synthesis and thermal decomposition processes. It was found that the Fe@NPC composites were uniformly distributed on the carbon fibers matrix. As a result, EM wave absorbing performances were greatly promoted via the synergic effects among Fe nanoparticles , nanoporous carbon and carbon fibers. A strong reflection loss ( RL ) of −46.2 dB and a wide absorbing bandwidth of 5.2 GHz ( RL < -10 dB) with a matching thickness of 2.5 mm were achieved for the Fe@NPC@CF composites with a low filling ratio of 25%. Therefore, this work not only paved the way for development of biomass as a green, low-cost and renewable high-performance carbon-based absorber, but also provided a good design and fabricating concept for the composite materials of EM wave absorber.
