Dual-emission carbon dots with strong yellow fluorescence (Y-CDs) were prepared by one-step hydrothermal method from p-aminophenol and ethylenediamine. Two emission centres appeared at 380 nm and 520 nm under excitation of 270 nm. After adding Al 3+ , the fluorescence at 520 nm decreased due to static quenching, while the fluorescence at 380 nm gradually increased. Therefore, it could be used for ratiometric detection of Al 3+ . In addition, the synthesized Y-CDs were concentration dependent, and the occurrence of dual emission peaks was considerably related to the concentration. When the concentration of Y-CDs decreased, the intensity of its emission peak at 380 nm gradually increased. There was an excellent linear relationship between the concentration of synthesized Y-CDs and the ratio of two emission peaks after adding Al 3+ , which had been used for the detection of Al 3+ in actual water samples. Moreover, the synthesized Y-CDs were successfully applied to A549 cell imaging .

In this work, hierarchical flower-like MoS2 microspheres synthesized through a facile hydrothermal approach are used as a cathode for aluminum-ion batteries. They exhibit an initial specific discharge capacity of 153.6 mAh g–1 at a current density of 50 mA g–1 and deliver a stable capacity of 112.2 mAh g–1 with a Coulombic efficiency of 92.4% over 100 cycles on account of the unique hierarchical structure, which provides abundant space for aluminum storage. Moreover, the characterization results confirm that Al3+ ions can be intercalated into the MoS2 phase to form AlxMoS2 during the discharge process. The density functional theory calculation results indicate that the structure of MoS2 can be stabilized during the intercalation/deintercalation process.

In this work, a new trivalent ion-mediated one-pot synthetic protocol is reported to create two well-defined optical absorbance and photoluminescence (PL) emissions in all-inorganic halide perovskite nanocrystals (NCs). The foreign M3+ cations (M = Bi, Al, In), typically from BiBr3, BiFeO3, BiCl3, AlBr3 or InBr3, function as capping ligands for generating a growth-constrained thinner nanoplatelet (NPL) population displaying the quantum confinement effect. The formation mechanism of the growth-constrained NPLs is proposed based on density functional theory (DFT) on the different slab energy of the representative NPLs achieved in the presence of Bi3+ ions and the density of states (DOS) of the supposed bulk perovskites. Notably, the formation of two groups of NCs with different sizes allows for the generation of dual optical absorbance and PL emissions. The influence of the M : Pb molar ratios on the precursors is systematically elucidated, from which the relative intensity and position of each PL emission can be fine-tuned. By virtue of the representative NPLs with well-defined green and blue emissions, the M3+-assisted synthetic protocol provides a facile and cost-effective route for producing unique NCs and nanostructures for optoelectronic device applications.

In this study, a new fluorescence probe HMAQ based on quinazoline and diaminomaleonitrile was constructed for sensing ClO − and Al 3+ . A fluorescence blue-shift with 102 nm together with a color change from golden-yellow to colorless was found by hypochlorite-induced hydrolysis of –CH=N- group to release the initial fluorophore. Besides, Al 3+ could cause a 72-nm blue-shifted emission spectra and a color change from golden-yellow to brown. As expected, HMAQ exhibited a satisfactory selectivity and sensitivity to ClO − /Al 3+ with a quick response. Most notably, the reversibility of the [HMAQ+Al 3+ ] complex could be used to detect ClO − and Al 3+ simultaneously without mutual interferences. The detection limits of HMAQ for ClO − and Al 3+ were turned out to be 10.2 nM and 1.56 nM, respectively. The high-performance results of real-time detections demonstrated the enormous potential of HMAQ in real-water samples and living cells.

The homogeneous Yb 3+ /Al 3+ /B 3+ -co-doped silica glasses were prepared via a sol-gel method. The impact of B 2 O 3 addition on the physical and optical properties and network structure was systematically studied. The network structure was investigated by the Fourier Transform Infrared (FT-IR), Raman spectra, and Solid State Nuclear Magnetic Resonance (SSNMR). Herein, B 2 O 3 addition can continuously decrease the refractive index and density. When B 2 O 3 is lower than 2 mol%, B 2 O 3 addition can obviously decrease the scalar crystal field parameters, Yb 3+ asymmetry degree, Yb 3+ cross-sections, due to the generation of Yb–O–B bonds at the cost of partial Yb–O–Al/Si ones. When B 2 O 3 is more than 2 mol%, FT-IR, Raman spectra, and SSNMR results indicate that further increased B atoms prefer to connect with Si and Al rather than Yb. Consequently, the above parameters are basically unchanged. Based on the results, an intuitive model of structure and properties evolution during the substitution of SiO 2 by B 2 O 3 has been established.

Manganese-based halides like Li 2 MnCl 4 are attractive for their cost-effectiveness and inverse spinel structure with ion channels. Their use as solid-state electrolytes is limited by low ionic conductivity at room-temperature and poor stability at the lithium interface. Current strategies focus on single-cation doping, which often offers limited conductivity improvements or causes side effects. This study proposes a dual-site cation-anion co-doping strategy to modify lattice defects and Li + migration pathways, thereby enhancing interfacial stability with metallic lithium. Lattice distortion is greatly induced, and Li + vacancy concentration is optimized in Li 1.7 Al 0.1 MnCl 4- x F x ( x = 0–0.7) by substituting Al 3+ at octahedral sites and partially replacing Cl − with F − . Structural and electrochemical tests show that moderate co-doping maintains the cubic structure and greatly improves Li + transport. The best Li 1.7 Al 0.1 MnCl 3.9 F 0.1 exhibits a room-temperature ionic conductivity of 5.2 × 10 −5 S cm −1 , nearly ten times higher than pristine Li 2 MnCl 4 , with a reduced activation energy of 0.45 eV. The distribution of relaxation time analysis further reveals that interface-related relaxation processes remain relatively stable over long time scales. Stable lithium stripping/deposition was demonstrated for hundreds of hours at 0.1 mA cm −2 in lithium-symmetric batteries. However, polarization during long cycling indicates challenges with interfacial stability. This work underscores the impact of dual-site co-doping in developing low-cost, high-performance manganese-based halide solid-state electrolytes.

Dual-network design with ion-electron conduction balances mechanical and electrical performance. • High tensile strength, toughness, and conductivity ensure stable sensing foundation. • Rapid photoinitiated fabrication enables efficient and scalable hydrogel preparation. • Long-term stable sensing performance sustained over 1000 stretching cycles. • Broad detection ranges from large joint movements to subtle facial expressions. Achieving mechanically robust yet highly conductive hydrogels remains a central challenge for skin-interfaced wearable sensors, as network reinforcement often compromises charge transport and long-term sensing stability. Here, we report a coordination-Hofmeister dual-network engineering strategy for constructing a chitosan/PAA/PEDOT:PSS conductive hydrogel that integrates high mechanical strength, efficient charge transport, and environmental adaptability. A primary hybrid network (PECA) is formed in an ethylene glycol/water medium through one-pot photoinitiated polymerization, simultaneously establishing covalently crosslinked PAA chains, Al 3+ -mediated coordination between PAA and the PSS component of PEDOT:PSS, together with electrostatic interactions involving chitosan, and a homogeneously distributed conductive polymer phase. Subsequent ammonium-sulfate-induced Hofmeister salting-out promotes polymer-chain dehydration and entanglement, generating a compact secondary physical network and yielding a double-network hydrogel (DECA). The optimized DECA hydrogel achieves a tensile strength of 1.74 MPa, toughness of 6.69 MJ m −3 , and conductivity of 6.52 S/m, corresponding to 6.9-, 5.0-, and 81-fold enhancements over the pristine hydrogel, respectively. Benefiting from reversible coordination/hydrogen-bonding interactions and stable electronic-ionic conductive pathways, the hydrogel sensor maintains reproducible resistance responses after 1000 stretching cycles. When mounted on human skin, the DECA sensor enables real-time monitoring of multi-scale physiological motions, from large joint movements to subtle facial expressions. This work provides a facile strategy for resolving the mechanical-electrical trade-off in conductive hydrogels and advances their application in durable wearable electronics. An Al 3+ coordination and Hofmeister salting-out strategy is used to engineer chitosan/PAA/PEDOT:PSS double-network conductive hydrogels. The coordinated and sulfate-reinforced network simultaneously improves tensile strength, toughness, conductivity, and cyclic sensing stability, enabling skin-mounted strain sensors for real-time monitoring of joint motion and subtle facial expressions.

As Al 3+ is an important ion in industry and daily life, the fluorescence sensor with high sensing selectivity and sensitivity for Al 3+ in rapid, simple and in-situ way was always anticipated. In this work, a “turn-on” fluorescence sensor ( CBC ) based on a crown ether-bridged biscyanostilbene carboxylic derivative exhibited excellent fluorescence response for Al 3+ with obvious fluorescence change from dark blue to bright blue-green color. The high sensing selectivity for Al 3+ was observed among 28 kinds of metallic cations and anions. The detecting limitation was as low as 1.68 × 10 −8 M. The sensing mechanism was proposed as that Al 3+ was bound by two carboxyl groups, resulting in the rotating restriction of aromatic groups and strong fluorescence. This sensing ability of CBC for Al 3+ was evaluated by TLC analysis, stamp experiment and simulated water samples, suggesting the excellent application potential on simple, rapid and in-situ detection of Al 3+ in real environments.

A novel benzo[ d ]thiazole derivative (B31) was synthesized via a green method. Aggregation–induced emission (AIE) behavior was investigated in a dimethyl sulfoxide (DMSO)/water mixture. The solution of B31 exhibited fluorescence emission at approximately 500 nm with maximum intensity observed at 40% water content. B31 functioned as a selective fluorescence chemosensor for Al 3+ ion with detection limit of 24 nM. In addition, a new complex [Al( B31 –2H)(NO 3 )] (AlB31) was prepared and characterized by electrospray ionization mass spectrometry (ESI–MS), infrared spectroscopy (IR), and proton nuclear magnetic resonance spectroscopy ( 1 H NMR) spectra. Notably, the quantum yields of AlB31 complex in DMSO was approximately 60-foldhigher than that of the free B31 ligand, accompanied a significant Stokes shift. Density functional theory (DFT) calculations were performed to rationalize the optical properties of the studied compounds. The weak fluorescence of B31 is likely caused by the rotation of the naphthalene ring around the –CH = N– bond in the S 1 excited state. A plausible photoemission mechanism for the AlB31 c omplex has also been proposed.

Highly sensitive monitoring of pesticides has garnered attention for food safety. Here, a ratiometric fluorescent probe (AG-CDs-Al 3+ /CdTe QDs) was fabricated for specific and sensitive sensing of glyphosate. Surface modifications revealed the chelation-enhanced fluorescence process between the surface -OH of AG-CDs and Al 3+ . Positively charged green-emission AG-CDs-Al 3+ assembled with negatively charged red-emission CdTe QDs, and photoinduced electron transfer (PET) occurred from CdTe QDs to AG CDs-Al 3+ . Glyphosate specifically coordinated with Al 3+ , causing remarkable variations in F 500 /F 630 (linear range, 0.2–4.0 μM; detection limit, 5.7 nM) and a distinguishable green-yellow-red color change on the paper platform (linear range, 0.5–8.0 μM; detection limit, 26 nM). Furthermore, for real sample analysis, the sensor has the advantages of fast response (5 min), excellent accuracy (spiked recoveries, 95.0–105.0 %), high precision (relative standard deviation, < 3.33 %), and superior specificity, which endowed the designed sensing platform with great potential practicality in the field of food analysis.

Color-tunable luminescent hydrogels have shown significant potential in smart display devices, data encryption and multilevel anti-counterfeiting due to their excellent flexibility, functional versatility and optical properties. However, developing hydrogels that exhibit prominent optical decryption capabilities while maintaining robust mechanical properties remains a challenge. Herein, we present an Al3+ stimulus-triggered luminescent hydrogel with the integrated properties of wide multi-color tunability, self-healing capacity, high strength (160%) and an impressive toughness (180 kJ m−3). The double-network in the hydrogel with rich hydrogen bonds is well compatible with various luminophores. These include luminescent layered rare earth hydroxide nanosheets (LRH NSs) with red/green (R/G) emission and a chemosensor molecule that displays a fluorescence “turn-on” change in blue (B) emission only in the presence of Al3+ as a stimulus. Consequently, this smart hybrid hydrogel not only provides an adjustable tool for tuning the visible color of soft materials based on orthogonal responsive R/G/B three-primary-color luminescence, but also acts as a specific key for enabling color-switchable anti-counterfeiting and information encryption/decryption. These unique optical properties of the luminescent soft material highlight its potential as a hydrogel-based functional platform for the development of intelligent and color-tunable cryptographic devices with low cost, facile synthesis, and good processability.

A bifunctional fluorescent pyrene-based probe, PYR , was designed by incorporating pyridine and phenolic hydroxyl moieties into pyrene fluorophore, which exhibited ratiometric fluorescent response toward Al 3+ . PYR underwent unique monomer-excimer conversion in ratiometric manner through the formation of a 2:1 coordination complex and accomplished with fluorescent color variation from green to blue. PYR displayed excellent selectivity , high sensitivity (LOD = 0.33 μM), rapid response (<45 s), and good cytocompatibility to Al 3+ . Notably, a fluorescent cellulose membrane decorated with PYR was successfully developed and applied for accurately quantify of Al 3+ in diverse actual samples, and high-efficiency removal (∼96%) of Al 3+ from water systems, with sustainable recycling performance up to 10 times. Bifunctional membranes also played an important role in reducing the LOD of Al 3+ to 16 nM through the preconcentration process. Therefore, this study is crucial to the development of environmentally sustainable strategy for monitoring and removing pollution.
