A novel ratiometric fluorescent probe RhB-BODIPY-OH based on Rhodamine and boron dipyrromethene (BODIPY) platform for sensing Fe 3+ and Hg 2+ ions was synthesized by Click reaction. RhB-BODIPY-OH dendron was a hybrid fluorescent probe with reaction-based as well as lock/key-based detection sites, which contains four recognition positions including Schiff base C N functionality, triazole–triazole linker and the spirocyclic ring of the Rhodamine unit. Naked eye detection was realized with the obvious color change. In addition, low detection limit was calculated from titration results with the value were 7.74 × 10 −8 M for RhB-BODIPY-OH/Hg 2+ as well as 3.91 × 10 −7 M for RhB-BODIPY-OH/Fe 3+ , separately. The probe is highly sensitive, the detection time is less than 2s. On top of that, living cell imaging experiment was carried out, which demonstrated that RhB-BODIPY-OH is a good bioimaging agent in living cells. Eventually, amino-group-functionalized silica fluorescent nanoparticles (FNPs) encapsulating the RhB-BODIPY-OH dyes were prepared and characterized by transmission electron microscopy.

By tuning metal ions and combining with different dicarboxylates , four new semi-rigid thiophene-bis-pyridyl-bis-amide-based coordination polymers , namely, [Zn(3-bptpa)(1,3-BDC)]·DMA·2H 2 O ( 1 ), [Zn(3-bptpa)(5-MIP)] ( 2 ), [Cd(3-bptpa)(1,3-BDC)]·2H 2 O ( 3 ) and [Cd(3-bptpa)(5-MIP)]·4H 2 O ( 4 ) (3-bptpa= N,N′ -bis(pyridine-3-yl)thiophene-2,5-dicarboxamide, 1,3-H 2 BDC=1,3-benzenedicarboxylic acid, 5-H 2 MIP=5-methylisophthalic acid, DMA= N,N -dimethylacetamide), were solvothermally/hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction analyses, IR spectra , UV–vis diffuse-reflectance spectra (DRS), powder X-ray diffraction (PXRD) and thermal gravimetric analyses (TG). The structural analysis reveals that Zn-complexes 1 and 2 are similar 2D networks. While Cd-complexes 3 and 4 exhibit similar 2-fold interpenetrating 3D α -Po frameworks with the (4 12 ·6 3 ) topology. The photocatalytic properties for the degradation of methylene blue (MB) under ultraviolet light irradiation of the title complexes have been investigated in detail. Furthermore, the luminescent sensing behaviors for metal cations of 1–4 have been studied, the results indicate that 3 is an excellent fluorescent probe , with high sensitivity, selectivity , and simple regeneration, for environmentally relevant Fe 3+ ions.

Traditional fluorescent probes have challenges, including aggregation-induced quenching, biological incompatibility, and suboptimal selectivity. In this study, we developed a novel probe derived from natural rutin featuring an aggregation-induced emission (AIE) effect. Through hydroxy engineering of rutin, the optimized probe enables precise detection of Fe 3+ via 2:1 stoichiometric coordination. The probe demonstrates remarkable analytical performance, with a detection limit as low as 0.22 μM. Concentration-dependent responses were observed within 0–20 μM, with significant linearity ( R 2 > 0.99) in the 0–10 μM range. Density functional theory calculations reveal that the binding of Fe 3+ effectively suppresses intramolecular charge transfer. The hydroxy-engineered modification plays a pivotal role in facilitating complexation for bond formation and providing appropriate steric hindrance. This research establishes a new benchmark for natural product-based AIE probes and deepens understanding of the structure–activity relationships governing flavonoid-metal recognition.

Colorimetric and fluorescent dual mode detection methods have gained much attention in recent years; however, it is still desirable to develop new colorimetric and fluorescent dual mode nanosensors with more simple preparation procedures, low cost, and excellent biocompatibility. Herein, a colorimetric and fluorescent nanosensor based on B, N, S-co-doped carbon dots (BNS-CDs) was synthesized by one-step hydrothermal treatment of 2,5-diaminobenzenesulfonic acid and 4-aminophenylboronic acid hydrochloride. Using this nanosensor, a highly sensitive assay of Fe3+ in the range of 0.3–546 μM with a detection limit of 90 nM was provided by quenching the red emission fluorescence. It is more attractive that Fe3+ can also be visualized by this nanosensor via evident color changes of the solution (from red to blue) under sunlight without the aid of an ultraviolet (UV) lamp. Furthermore, the designed nanosensor can be applied for efficient detection of intracellular Fe3+ with excellent biocompatibility and cellular imaging capability, and it holds great promise in biomedical applications.

Smart theragnostic nanoplatforms exhibit great promise in clinical tumor treatment. The Fe-based Fenton reaction in tumor sites may generate reactive oxygen species to kill cancer cells with negligible side effects on normal tissues. However, its efficiency and duration are limited by the low intracellular concentration of H 2 O 2 , weak acidicity of tumor tissue, and low catalytic activity of conventional Fenton reagents. Herein, a facile strategy is proposed to efficiently overcome these obstacles. An efficient enzymatic/Fenton-starvation nanoreactor PMs loaded with glucose oxidase and perfluoropentane (PGPMs) is constructed through synthesizing methoxy-PEG-carboxymethy-modified iron (Fe 2+ /Fe 3+ )-based metal–organic frameworks (PMs), followed by loading glucose oxidase (GOx) and perfluoropentane (PFP). PGPMs accumulating in the tumor tissue exhibit tumor microenvironment-responsive biodegradable behavior and unusual catalytic activity for Fenton reaction advantageous over Fe 3+ -based MOFs. Meanwhile, encapsulation of GOx into PGPMs further significantly increases the catalytic activity for Fenton reaction and also induces starvation therapy. PGPMs also exhibit considerable capabilities of ultrasound and tumor microenvironment-responsive T2 MR imaging applicable for contrast-enhanced diagnosis. Both in vitro and in vivo studies demonstrate the great diagnostic and therapeutic potentials of this nanoreactor in tumor.

Realizing environment-friendly and thermal-driven self-healing polymers with robust mechanical properties is an important challenge for the development of next-generation smart materials. Herein, by combining dynamic phenol-carbamate bonds and Fe 3+ -catechol coordination bonds in polymer chains, novel hyperbranched waterborne polyurethanes (FTWPU) with desirable thermal-driven self-healing properties were prepared through two steps, i.e., introducing tannic acid to prepare tannic acid based waterborne polyurethane (TWPU) bearing phenol-carbamate bonds firstly, and subsequently further incorporating Fe 3+ ions to prepare FTWPU in possession of Fe 3+ -catechol moieties. The results exhibited that TWPU possessed good emulsion stability with differing tannic acid content, and improved thermal and mechanical properties, owing to the presence of cross-linking between polyurethane chains, and FTWPU still possessed outstanding storage stability, as well as much higher mechanical properties (tensile strength of 18.4 ± 0.4 MPa, elongation at break of 533.5 ± 5.2 %). Meanwhile, FTWPU presented desirable self-healing ability (i.e., healing efficiencies of tensile strength and elongation at break were 87.5 % and 91.9 %, respectively) after healing under 120 °C for 1.5 h and 85 °C for 30 min, demonstrating a satisfactory balance between good self-healing ability and high mechanical properties. Importantly, reversible phenol-carbamate bonds and metal coordination bonds are predominant factors during the healing process of FTWPU films, as well as high mobility of soft segments and hydrogen bonding effect play a significant role to achieve ultimate healing ability. We can envision that the promising design idea, based on synergistic effect between phenol-carbamate bonds and Fe 3+ -catechol coordination bonds, could provide inspiration for preparing self-healing polymers with superior mechanical properties.

This work reported a novel electrocatalyst , Fe 3+ -curcumin/multi-walled carbon nanotubes (MWCNTs) complex, for efficient detection of hydroxylamine by modifying the glassy carbon electrode (Fe 3+ -curcumin/MWCNTs-modified electrode). The Fe 3+ -curcumin/MWCNTs complex was prepared via a green and facile one-pot synthesis method and the as-prepared complex was characterized using TEM , EDS , XRD, XPS , and EIS. Subsequently, the Fe 3+ -curcumin/MWCNTs complex modified electrode was adopted as an electrochemical sensor for hydroxylamine detection. The catalytic peak current for sensing the hydroxylamine using the Fe 3+ -curcumin/MWCNTs-modified electrode was 9.5 times higher the catalytic peak current using the curcumin/MWCNTs-modified electrodes. The overpotential was reduced by 550 mV compared to MWCNTs-modified electrodes. The interfacial electron transfer rate was 0.37 s −1 for the Fe 3+ -curcumin/MWCNTs-modified electrode. Furthermore, the Fe 3+ -curcumin/MWCNTs-modified electrode exhibited outstanding sensing performance within analyte concentration range from 0.05 to 1100 μM (a low detection limit of 0.02 μM, S/N = 3). Finally, the constructed sensor was successfully adopted for the hydroxylamine detection from the hydrolysis of the pralidoxime iodide injections, demonstrating the practical applications.

Fe3+-incorporated hydrogels are particularly valuable for wearable devices due to their tunable mechanical properties and ionic conductivity. However, conventional immersion-based fabrication fundamentally limits hydrogel performance because of heterogeneous ion distribution, ionic leaching, and scalability limitations. To overcome these challenges, we report a novel one-pot strategy where controlled amounts of Fe3+are directly added to polyacrylamide-sodium acrylate (PAM-SA) precursor solutions, ensuring homogeneous ion distribution. Combining this with Photoinduced Electron/Energy Transfer Reversible Addition–Fragmentation Chain Transfer (PET-RAFT) polymerization enables efficient hydrogel fabrication under open-vessel conditions, improving its scalability. Fe3+concentration achieves unprecedented modulation of mechanical properties: Young’s modulus (10 to 150 kPa), toughness (0.26 to 2.3 MJ/m3), and strain at break (800% to 2500%). The hydrogels also exhibit excellent compressibility (90% strain recovery), energy dissipation (>90% dissipation efficiency at optimal Fe3+levels), and universal adhesion to diverse surfaces (plastic, metal, PTFE, and cardboard). Finally, these Fe3+-incorporated hydrogels demonstrated high effectiveness as strain sensors for monitoring finger/elbow movements, with gauge factors dependent on composition. This work provides a scalable, oxygen-tolerant route to tunable hydrogels for advanced wearable devices.

It is of great significance to develop carbon quantum dots (CQDs) using green carbon sources, which are cheap, non-toxic and harmless, and further expand their application scopes, e.g., fluorescence sensors, blue light screening. In this study, we have prepared Peperomia tetraphylla-based carbon quantum dots (PT-CQDs) with strong water solubility, good salt resistance, specific quenching reactions and excellent optical properties via a simple one-step hydrothermal method. In one application, PT-CQDs are utilized as a fluorescence sensor due to their high selectivity and sensitivity to ferric ions (Fe3+). The limit of detection (LOD) was 2.7 μmol·L−1. On the other hand, PT-CQDs/polyvinyl alcohol (PVA) films with excellent ultraviolet- (UV) and high-energy blue light (HEBL)-blocking properties were obtained. The obtained films exhibited a high blue light weight blocking rate of 100% in UV and 80% in HEBL. The concentrations of the composites could also be controlled to achieve the desired light-blocking rate. In addition, the composites were able to absorb blue light and convert it to other forms of light. These properties suggest their potential applications in the development of advanced blue light screening and fluorescence sensors.

Due to the frequent occurrence of marine oil spill accidents, the ecological environment is facing severe threats. However, some traditional oil-water separation methods suffer from issues such as high cost, environmental unfriendliness and low efficiency. Therefore, there is an urgent need to develop a simple and efficient oil-water separation membrane. Leveraging the non-toxicity and abundance of hydrophilic groups (such as -carboxyl and -OH) in tannic acid, this study, for the first time, forms a hydrophilic coating on the surface of polyimide membrane (PI) through the complexation of tannic acid with ferric chloride hexahydrate, thus fabricating a superhydrophilic/superoleophobic membrane for oil-water separation. The water contact angle (WCA) of the modified membrane drops to 0° within 5 s, while the underwater oil contact angle (UOCA) reaches up to 142°. Moreover, under the action of gravity, the membrane not only achieves a high water flux of 2100 L·m -2 ·h -1 but also attains a removal rate of over 90 % for various oil-in-water emulsions. In addition, the modified membrane exhibits excellent resistance to acids, alkalis, and salts, as well as outstanding oil-fouling resistance. This promising material offers a universal modification strategy with broad applications in wastewater treatment.

By means of post-synthetic treatment on the UiO-66 derivative with –SO3H, a novel luminescent hybrid material named Tb3+@UiO-66–SO3H has been prepared simply and efficiently. Given its wonderful luminescence properties like intense green emission, a long lifetime, a robust structure and photostability, it is further developed as a fluorescent probe for the sensing of trans,trans-muconic acid (tt-MA, a biomarker of benzene) and Fe3+, which are closely related to human health. Notably, Tb3+@UiO-66–SO3H shows an outstanding recognition ability for Fe3+ among common cations with a low detection limit (0.11 μM, 0.006 ppm). More importantly, Tb3+@UiO-66–SO3H can realize highly sensitive and selective detection of tt-MA (detection limit, 0.58 μM, 0.083 ppm). Besides, this rapid response probe is facilely prepared, non-toxic and reusable, showing the potential of Tb3+@UiO-66–SO3H in the practical monitoring of tt-MA and Fe3+.

A novel core-shell heterojunction photocatalyst Ta 3 N 5 @FeTaO 4 /Mn x O y was designed for efficient persulfate activation to enhance the photocatalytic performance. Ta 3 N 5 @FeTaO 4 /Mn x O y was synthesized using a two-step impregnation-calcination method, and tetracycline was selected as the model pollutant. The results indicated that the tetracycline degradation by Ta 3 N 5 @FeTaO 4 /Mn x O y was 3.79 and 13.42 times faster than those by Ta 3 N 5 @FeTaO 4 and Ta 3 N 5 , respectively. Pollutant degradation via radicals (·OH, SO 4 · − and O 2 · − ) and non-radicals (Fe(IV) and 1 O 2 ) was verified by probe tests, quenching experiments, and EPR analysis. The homologous growth heterojunction promoted the separation of charge carriers owing to the matched structure and seamless interface between Ta 3 N 5 and FeTaO 4 . The loaded Mn x O y enhanced persulfate adsorption and facilitated Fe 3+ /Fe 2+ cycling, consequently improving persulfate activation and the photocatalytic degradation of pollutants. This study reveals the often-overlooked role of iron-based catalysts to generate a wider range of reactive species, offering a new perspective to design Fenton-like photocatalytic materials.
