Here, strong magnetic anisotropy and a large topological Hall effect (THE) in self‐intercalated Cr1.61Te2 single crystals are reported, which are both highly desirable properties for future spintronic applications. These results demonstrate that Cr1.61Te2 is a soft ferromagnet with strong in‐plane magnetic anisotropy. Remarkably, distinct THE behaviors are observed in different temperature regimes, reflecting the intricate spin structures and competing exchange interactions. More interestingly, a large topological Hall resistivity, induced by microscopic non‐coplanar spin structures, emerges in the temperature range 70–240 K, reaching a maximum value of 0.93 µΩ cm at 150 K. Moreover, a sign‐reversed and weak THE is observed at low temperatures below ≈ 70 K, indicating the emergence of an additional topological spin structure with opposite topological charges. This work not only offers valuable insights into the correlation between magnetocrystalline anisotropy and topological phenomena in Cr1+xTe2 systems, but also provides a robust platform for engineering the evolution of complex spin textures that can be leveraged in diverse spintronic device applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simultaneous replication of such phototropic movement and volumetric growth in synthetic polymers is important but currently remains challenging. Here, the molecular design of a photoswitchable tricyanofuran (TCF) based hydrogel is reported that can concurrently display such phototropic movement and self‐growth in water under stimulation of light and pH. The macroscale growth of the hydrogel originates directly from the volume swelling induced by charge rise of TCF upon isomerization, which dramatically facilicates water/nutrients diffusion into the network. As the growing rate under each stimulation is independently regulated, TCF hydrogels are successfully developed displaying heterogeneous growth accompanied with phototropic bending deformation by taking the advantage of the differential growing rates induced by light and pH. Importantly, the phototropic deformation direction after secondary polymerization growth can be reversibly switched between positive and negative states modulating light irradiation and pH conditions. This tunability enables biomimetic replication of natural light‐responsive systems. The work provides a novel molecular design strategy for advancing the development of biomimetic systems with capability of phototropic deformation and self‐growth.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"26 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, natural biomass‐derived materials have demonstrated tremendous potential due to their inherent renewability, superior biocompatibility, and unique structural skeletons. This study proposes a rational molecular design strategy to produce rosin‐derived dehydroabietic acid‐quinoxaline (DAQx) as a natural electron acceptor, and triphenylamine is incorporated as an electron donor to construct a donor–acceptor (D–A) type structure. This approach develops biomass‐based aggregation‐induced emission (BioAIE) materials with twisted intramolecular charge transfer characteristics. By adjusting the conjugation extent and electron‐withdrawing capability of the DAQx skeleton, dynamic optimization of photophysical properties is achieved. The results indicate that the modified D–A‐type BioAIE materials not only exhibit remarkable solvent stimuli‐responsive behavior, enabling dynamic encryption‐decryption, but also realize precisely targeted imaging of subcellular organelles, benefiting from the inherent biocompatibility of the natural DAQx skeleton. This work provides a novel strategy for designing high‐performance BioAIE materials based on natural rosin‐based electron acceptor, while expanding the application potential of biomass‐based luminescent materials in intelligent anti‐counterfeiting and bioimaging fields, offering new insights for the high‐value utilization of rosin.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"97 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, an anionic covalent organic framework (COF)‐based aerogel (denoted as CCGA) is presented with both excellent selectivity and ultrahigh surface‐enhanced Raman scattering (SERS) detection sensitivity. The hierarchical architecture of CCGA synergistically integrates macroporous graphene scaffolds with micro‐mesoporous COF channels, facilitating rapid and selective capture of cationic dyes (>92% removal efficiency) via π–π stacking and electrostatic interactions, while exhibiting negligible affinity for anionic counterparts. This aerogel‐based enrichment strategy enables SERS detection of trace pollutants down to 1.65 × 10−5 mg mL−1 for rhodamine B (RhB) and 2.27 × 10−6 mg mL−1 for malachite green (MG). Furthermore, the heterojunction reduces the bandgap of graphitic carbon nitride and promotes visible‐light‐driven photocatalytic degradation, allowing self‐regeneration of the aerogel across nine cycles. Demonstrating practical applicability, the CCGA exhibits versatility in addressing complex cationic pollutants and operates effectively within real wastewater matrices via a portable filtration system. This work advances multifunctional material design by integrating selective adsorption, molecular‐level detection, and solar‐driven regeneration strategies, presenting a scalable approach for next‐generation water remediation technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"14 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a copper‐based metal‐organic framework (Cu‐MOF) functionalized hydroxyapatite/bacterial cellulose (Cu‐MOF@HB) composite nanofibers separator is designed to address these critical challenges. The hierarchical porous structure of the Cu‐MOF@HB separator enhances electrolyte wettability and adsorption. Density functional theory (DFT) calculation reveals that abundant open metal sites within the Cu‐MOF promote PF6− anion immobilization via Lewis acid‐base interactions, effectively increasing the Li+ ion transference number and facilitating faster Li+ ion migration within the separator. Consequently, the Cu‐MOF@HB separator effectively mitigates concentration polarization at the graphite anode/separator interfaces, suppressing Li dendrite formation and improving Coulombic efficiency. This significantly improves fast‐charging performance in high‐loading LiFePO4 (15.5 mg cm−2)||graphite (7.5 mg cm−2) batteries, achieving 79% capacity retention after 600 cycles at 3 C, compared to only 16% with a conventional polypropylene (PP) separator. Critically, the Cu‐MOF@HB separator also exhibits exceptional thermal stability and flame retardancy, enhancing battery safety. This work highlights the significant potential of interfacial engineering of separators, particularly through the incorporation of functional MOFs and thermally stable inorganic nanofibers, for achieving safe and high‐performance fast‐charging LIBs.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"29 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144669708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, PhA‐Fe3+ complexes constructed by controllable coordination assembly are presented, based on metal‐organophosphorus biphasic interfacial coordination reactions, and use the PhA‐Fe3+ complexes to regulate the interfacial polymerization (IP) process to generate polyamide (PA) nanofiltration membranes. The PhA‐Fe3+ complexes impart a high density of long‐range electrostatic and short‐range hydrogen bonding forces to the amine monomers and provide tunable charge densities through flexible metal‐organophosphate coordination. Hydrogen bonding and strong electrostatic interactions spatially enrich the amine monomers and temporally slow down their diffusion into the hexane phase, as demonstrated by molecular simulations, resulting in a PA/PhA‐Fe3+ membrane with increased surface area, enhanced microporosity, lower thickness, higher water density near pores, and nanoscale spotted structures. Those structures are recognized as the key factor in achieving a water permeance of 19.2 L m−2 h−1 bar−1, alongside a MgCl2 rejection of 96.7% and a Li+/Mg2+ selectivity of 24.1 (Mg2+/Li+ mass ratio = 20), surpassing those of reported nanofiltration membranes.
