However, conventional characterization techniques struggle to capture the dynamic processes and flooding at TPB. To address this, we develop operando electrochemical magnetic resonance imaging (EC-MRI), an inherently non-invasive technique sensitive to 1H, which probes both bulk and boundary regions, enabling real-time visualization of TPB evolution and a deeper understanding of its function at the device level under operational conditions. In a study of proton exchange membrane fuel cell (PEMFC), with a focus on the kinetically sluggish O2 reduction reaction in cathode, operando EC-MRI quantitatively illustrates the interplay between power output, water content, and TPB evolution. It reveals that the TPB maps undergo significant spatial and dynamic variations, with TPB deterioration, rather than apparent water accumulation, directly triggering flooding, as proved using catalysts with different water generation and adsorption capabilities. Our finding opens new perspectives on water management and TPB design, with potential applications in other critical electrochemical processes such as H2 oxidation, CO2 reduction, and N2 reduction, underscoring the value of operando EC-MRI for real-time diagnostics of electrochemical devices.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"47 1","pages":"e202506183"},"PeriodicalIF":16.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136799","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, the commercial application of LRMOs is constrained by the surface structure degradation and lattice oxygen release, resulting in low initial coulombic efficiency (ICE) and rapid voltage and capacity decay. Herein, we propose a facile sorbic acid‐assisted surface treatment strategy to construct homogeneous multifunctional interface layers composed of layered‐spinel heterogeneous structure and oxygen vacancies on the surface of LRMOs, which enhance the structure stability and improve the activity and reversibility of the anionic oxygen redox reactions. The multifunctional interfacial layers effectively suppress irreversible oxygen release and alleviate unfavorable layered‐spinel phase transformation. As a consequence, the treated LRMOs cathode displays improved ICE of 88.3%, high capacity retention rate (87.9% at 1 C after 150 cycles) and low voltage decay ratio (1.26 mV per cycle). These findings provide a valuable new idea to improve the comprehensive electrochemical performance of LRMOs through multi‐strategy synergistic interface engineering techniques.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"22 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136734","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}

As a result, there is considerable interest in improving DNP efficiency, particularly through the development of new polarizing agents (PAs). Here, a series of 32 PAs, including 26 dinitroxide and 6 hetero biradicals, of which 11 are introduced for the first time, were evaluated in DNP NMR experiments at magnetic field strengths of 9.4 T, 14.1 T, and 21.1 T.

A detailed comparison of the enhancement factors, polarization build-up times, contribution factors, and the resulting overall sensitivity factors is provided. We find that the class of narrow-line-broad-line biradicals not only yield the best performance at high field (21.1 T and 14.1 T), but also remain among the best at intermediate fields (9.4 T). Specifically, we find that SNAPol-1 and HyTEK2 are consistently among the best performing radicals at any field. Among the dinitroxide biradicals, notably at 9.4 T, the AsymPol-POK and M-TinyPol families stand out in proton-dense aqueous matrices, and a newly-developed dinitroxide, NaphPolCbo, is found to provide the best overall sensitivity factor in organic solvent.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"33 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136963","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}

Up to date, exciton regulation is still in its infancy. Here, via linkage engineering of covalent organic frameworks (COFs), we propose a fully conjugated sp2 carbon-linked COFs (sp2c-Py-Bpy COFs) with strong exciton interaction and fast ISC for boosted 1O2 photosynthesis. The sp2c-Py-Bpy COFs delivers a record-high 1O2 yield (624 μM min-1) with 100% selectivity, which is ca. 8 times that of the traditional imine-bridged COFs (Im-Py-Bpy COFs, ca. 95.8% selectivity), outperforming documented systems. Transient absorption spectroscopy and theoretical investigations demonstrate that the fully conjugated sp2 carbon linkage of sp2c-Py-Bpy COFs can enhance Coulomb interaction, promote ISC and push forward the transfer of triplet exciton to the O2 adsorption sites throughout the COFs matrix, jointly facilitating the energy transfer process for efficient 1O2 photosynthesis and bypassing the traditional electron transfer process. Hence, sp2c-Py-Bpy COFs can selectively degrade acetaminophen within minutes under visible light irradiation and enables stable degradation of emerging pollutants in a continuous flow membrane reactor (20 × 30 × 2 cm) utilizing natural sunlight and dissolved O2.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"172 1","pages":"e202509141"},"PeriodicalIF":16.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136711","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}

These devices exhibit a mixed conducting figure of merit µC* of 118 F cm−1 V−1 s−1, three times higher than the copolymer without hydrogen bond, along with simultaneously improved volumetric capacitance and electron mobility. These improvements are attributed to the unique microstructure created by hydrogen bond, which results in a closer π-π stacking distance within smaller crystalline domain sizes. Additionally, a cost-effective post-processing side chain removal method is proposed, which retains high performance in n-type OECTs. Remarkably, inverters based on the hydrogen-bonded terpolymer demonstrate high gain and self-healing capabilities through solvent vapor exposure and annealing treatment.

However, nanomedicine only responsive to the cancer cell-related enzyme is not very effective in pancreatic tumors because successive transcytosis cannot be established among the cancer cells, which are scattered in a large number of cancer-associated fibroblasts (CAFs). Here are reported dual-enzyme responsive 7-ethyl-10-hydroxycamptothecin (SN38)-polymer conjugates capable of inducing transcytosis among cancer cells and CAFs to infiltrate pancreatic tumors efficiently. The conjugates are zwitterionic for long blood circulation. Once in the tumor, the γ-glutamyl transpeptidase (GGT) overexpressed on the tumor endothelial and cancer cells, or the fibroblast-activated protease (FAP) on CAFs, can cleave the γ-glutamylamide or the prolylglycine dipeptide amides, producing primary amines. The cationized conjugate then induces transcytosis among cancer cells and CAFs, establishing successive intercellular transport to infiltrate the tumor. The conjugates' enzyme reactivity and overall hydrophobicity determine their cationization and transcytosis behaviors. The conjugates with high hydrophobicity and fast cationization show potent antitumor activity in pancreatic cancer patient-derived xenograft and orthotopic tumor models. This study provides an active transportation strategy to overcome the delivery barrier of tumors with rich stroma cells.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"3 1","pages":"e202506038"},"PeriodicalIF":16.6,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144136680","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}

Herein, we report a topologically entangled polymer electrolyte featuring ionophilic-protonation dual side chains. The ionophilic functional groups on these side chains provide abundant coordination sites, significantly enhancing Li+ transport, while exposed carboxyl (-COOH) groups induce protonation on the cathode surface, effectively suppressing transition metal (TM) ion migration.
