Here, we demonstrate that short-chain ether-functionalized metal-organic frameworks (S@MOFs) meet these requirements by efficiently tailoring Li⁺ coordination and reconstructing the electrode/electrolyte interphase, achieving durable interfacial ion transport kinetics. Synergistic experimental and theoretical investigations demonstrate that the S@MOF-based electrolyte features distinctive pseudosuspension characteristics, harnessing ether chemistry that affords Li-metal compatibility and Li-salt coordination in concert with MOF's abundant binding sites and ordered rigid frameworks. The resultant S@MOF-based electrolyte delivers robust thermodynamic stability across -10 to 60 °C, even in LiNi0.8Co0.1Mn0.1O2 (NCM811)||Li full-cell configurations. Under lean-electrolyte and 50 µm-thick Li-metal configurations, it achieves 92.40% capacity retention for LiCoO2||Li after 1000 cycles. Remarkably, 90.70% for quasi-solid-state NCM811||Li (500 cycles), and 93.21% for Na3V2(PO4)3||Na (3000 cycles) were obtained, confirming its broad applicability across alkali-metal battery chemistries.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"59 1","pages":"e202518384"},"PeriodicalIF":16.6,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there is still a lack of effective CSDT agents with long-term stability, excellent water solubility, biocompatibility, and highly efficient catalytic activities. To address these challenges, we report a rare sonosensitive polyoxometalate (POM), H11[Er2Sb2W7O23(OH)(DMF)2(SbW9O33)2]·17H2O (ErSbW), featuring an atomically precise capsule-like structure with good solubility, molecular stability, and biosafety under physiological conditions. In vitro studies reveal ErSbW's remarkable CDT efficiency in catalyzing the generation of reactive oxygen species (ROS). More importantly, the efficiency can be further distinctly augmented by three times with the presence of ultrasound irradiation, suggesting a pronounced synergistic enhancement effect in ErSbW. Most notably, ErSbW-mediated CSDT achieved complete eradication of deep-seated tumors in a melanoma model at the dose of 35 µg kg-1.

However, the development of highly selective and durable catalysts that perform reliably across varying operational conditions remains challenging. In this work, we report the synthesis of lithium-intercalated CuInP2S6 (Li-CIPS) with a layered structure via a one-step chemical vapor transport method. Compared to pristine CuInP2S6, lithium intercalation in Li-CIPS facilitates the rapid production of ultrathin CuInP2S6 nanosheets through simple soaking in water. Experimental and theoretical investigations reveal that these ultrathin Li-CIPS nanosheets contain abundant sulfur vacancies (Vs), which can substantially enhance the CO2RR activity while suppressing the competing hydrogen evolution reaction. As a result, the Li-CIPS catalyst achieves over 90% Faradaic efficiency (FE) for formate production across wide current densities ranging from 100 to 800 mA cm-2, and it maintains stable operation over 100 h at 200 mA cm-2.

The pendant C6F5 groups accelerate catalysis through fluorine-specific π-stacking interactions and improve obtained molecular weights compared to the non-fluorinated variant giving access to high weight materials (Mn,max. > 100 kg mol-1) with thermal and mechanical properties competitive with commodity plastics. These C6F5 groups then act as reactive handles in the material for efficient post-polymerisation modification (PPM) in solution, allowing fine-tuning of thermal, mechanical, optical, and solubility properties. PPM can even be performed on material surfaces, films and fibres can be selectively modified without dissolution. Lastly, degradation enables quantitative recovery of fluorine centres as sodium fluoride, offering a sustainable end-of-life option for the incorporated fluorine.

The crystalline nature of the membrane allows periodically arranged porphin molecules, enabling stable molecular recognition effect.
