Herein, we show that the defective La(OH) 3 nanorods bearing an inherent hydroxyl chainmail circumvent these two bottlenecks simultaneously. The chainmail is proposed to be capable of reconstructing the interfacial hydrogen‐bond continuum into a proposed proton‐relay highway that accelerates water‐dissociation‐limited proton delivery, while acting as a proposed biomimetic, multisite hydrogen‐bonding shield that sequesters macromolecular DOM to protect active sites from fouling. Demonstrated for the electrocatalytic hydrodechlorination reaction, the catalyst achieves highly effective dechlorination of florfenicol across pH 3.0–13.0 and sustains exceptional stability in high‐chemical oxygen demand (COD) matrices (1000 mg L −1 humic acid), outperforming most state‐of‐the‐art catalysts. Continuous‐flow treatment of real aquaculture and pharmaceutical effluents confirms sustained dechlorination efficiency and pronounced toxicity abatement. By revealing how this seemingly passive OH − chainmail orchestrates proton transfer and molecular sieving, this work establishes a broadly applicable design paradigm for fouling‐resistant electrocatalysts operating in complex aqueous environments.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"23 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374434","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 twisted‐planar‐twisted (TPT) MR‐TADF emitter named A‐BFCz is synthesized via an asymmetric π‐extension molecular‐design strategy. The asymmetric π‐extended conjugation can retain the locally excited (LE) character of the singlet state and accelerate reverse intersystem crossing (RISC) kinetics via potentially accessible high‐lying RISC pathways, resulting in narrowband deep‐blue emission with a full width at half‐maximum (FWHM) of 17 nm, a fast RISC rate constant approaching 10 6 s −1 , and a near‐unity photoluminescence quantum yield (PLQY). Meanwhile, the dual twisted peripheral substituents on the TPT backbone are beneficial to solid‐state packing behavior by spatially separating adjacent molecules and thus suppressing undesired intermolecular π–π stacking interactions. In addition, the centrally located B–N‐fused rigid scaffold maintains a well‐preserved planar configuration, leading to a horizontal dipole ratio of 99%. Consequently, the non‐sensitized deep‐blue OLEDs based on A‐BFCz achieve a peak external quantum efficiency (EQE) of 42.8%.

The simulations reveal rapid initial protein aggregation followed by slower structural maturation, during which interprotein interaction energy and contact networks continue to evolve. A simulation‐derived concentration‐dependent crossover separates multi‐cluster vs single‐cluster regimes and DLS shows larger assemblies at higher experimental concentrations. The simulations further delineate region‐specific secondary‐structure reorganization and CD demonstrates concentration‐sensitive structural changes with a distinct secondary‐structure redistribution. Moreover, the simulations predict concentration dependence in the contribution of intermolecular contact network reorganization; the L1, L3, and L5 linker regions supplied many of these contacts, with L3 providing the dominant contribution. Overall, these findings establish a molecular‐level framework where concentration governs RfA2 self‐assembly and continued conformational and intermolecular reorganization during maturation, providing insight into sequence‐ and assembly‐level principles regarding iridophore optical function and reflectin‐based materials design.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"20 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374423","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, we employ host‐guest encapsulation to functionalize otherwise underutilized pore space of macrocycle‐based MOFs by introducing an organic salt guest, N‐(2‐trimethylammonioethyl)pyridinium dibromide (PyBr) within the cage‐like units of resorcinarene‐based uranium‐organic frameworks (UOF‐1D and UOF‐2D). While maintaining the host framework well, such a modification creates a Br − /N + ‐rich pore microenvironment in as‐synthesized PyBr@UOF‐1D and PyBr@UOF‐2D. The resulting materials exhibit gas‐phase iodine uptakes of up to 3.50 g·g −1 , markedly exceeding those of the pristine frameworks, free guests, and physical mixtures. Spectroscopic analyses and calculations show that confinement enriches iodine around guest sites, where Br − polarizes I 2 and promotes polyiodide/polyhalide formation, while N + electrostatically stabilizes the resulting anions. The enhanced capture originates from improved pore utilization through cooperative confinement and guest‐derived binding interactions. Its successful application to both 1D and 2D UOFs demonstrates the adaptability of guest‐engineered pore microenvironments across distinct architectures, offering a route toward target‐specific separations.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"18 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374432","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, a multi‐modulation strategy via thickness‐confined Mo‐VO 2 /CNTs composite films is adopted to resolve these issues. By controlling the in‐situ growth on flexible CNTs films, Mo‐VO 2 with an appropriate thickness can partially allow IR information transmission of CNTs. The high‐conductivity CNTs scaffold effectively pulls down the radiative baseline, escaping the “extreme‐emissivity trap”, while Mo 6+ ‐induced band modulation and interfacial charge redistribution optimize the modulation amplitude (Δε) to 0.335 (0.795–0.460). Crucially, the CNTs network provides the massive free‐electron reservoir required to overcome shielding deficiency of VO 2 , elevating EMI shielding performance to an exceptional 62–76 dB. Furthermore, leveraging Joule heating effect as a compensatory dimension, the composite films enable active IR camouflage across extreme thermal mismatches (60 C–75°C). This work integrates desirable baseline IR optical modulation with highly efficient electromagnetic protection, redefining the design paradigm of advanced protective materials.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"11 4 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374433","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}

Nevertheless, the insufficient electrical conductivity of NiO x and the limited number of binding sites on its surface lead to incomplete monolayer coverage, resulting in substantial interfacial charge losses that constrain efficiency improvements. To address these issues, we introduce hydroxyl‑rich sodium gluconate (SG) into the NiO x solution. Gluconate anions from SG modulate the electronic properties of NiO x , thereby enhancing its conductivity. Meanwhile, the abundant hydroxyl groups along the SG backbone furnish additional hydrogen‐bonding sites for the subsequent adsorption of the SAM, promoting the formation of a compact and well‐ordered interfacial molecular layer. This dense SAM not only suppresses leakage currents but also optimizes the energetic cascade at the heterojunction, ultimately enabling the resulting IPSCs to achieve a power conversion efficiency of 26.24%. During maximum‐power‐point operation under ISOS‑L‑1 protocol, the optimized device preserves 91.6% of the starting output after 1000 h.

Here, we develop a co‐assembly strategy by incorporating two bisphosphonic acid molecules with distinct linker structures, denoted S1 and S2, into the widely used carbazole‐based SAM [4‐(3,6‐dimethoxy‐9H‐carbazol‐9‐yl)butyl] phosphonic acid (MeO‐4PACz). Compared with S1, S2 exhibits improved conformational compatibility with MeO‐4PACz. The S2/MeO‐4PACz pair also features stronger hydrogen bonding and π–π interactions. In addition, S2 possesses a larger molecular dipole and adsorbs more favorably on indium tin oxide. These molecular attributes promote more continuous and spatially uniform coverage. They also strengthen substrate anchoring and homogenize the interfacial potential distribution. The resulting S2‐based co‐assembled SAM (Co‐SAM) provides favorable energy‐level alignment, facilitates hole extraction, and suppresses nonradiative recombination. It also reinforces the buried interface against cyclic thermal stress. Residual stress accumulation is alleviated, interfacial morphology is preserved, and perovskite phase degradation is retarded. Consequently, inverted perovskite solar cells (PSCs) based on the S2 Co‐SAM achieve a power conversion efficiency of 27.01% and retain 92.8% of their initial efficiency after 500 temperature cycles between −40°C and 85°C.
