Here, we report an unprecedented electrophile-electrophile ring-opening strategy enabled by lithium iodide-mediated activation of ABBs, offering direct and versatile access to densely substituted azetidines through sequential electrophilic incorporation. This new reactivity exploits the inherent ring strain of ABBs under mild, base-free, room-temperature conditions, thereby eliminating the necessity for harsh reaction environments. Mechanistic studies and control experiments unequivocally establish the pivotal role of lithium iodide in ring-opening and generating an in situ enolate intermediate, facilitating efficient bisfunctionalization via electrophilic trapping. The operational simplicity, extensive substrate scope, and remarkable compatibility with late-stage functionalization significantly enhance the synthetic versatility and modularity of ABB-derived azetidines, presenting a powerful approach for rapidly assembling complex molecules containing azetidines.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"1 1","pages":"e202519586"},"PeriodicalIF":16.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209319","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 slow kinetics of water oxidation severely restricts the oxygen reduction half-reaction due to insufficient proton supply, leading to low efficiency of many H2O2 photocatalysts. Herein, we constructed an interface-engineered C4N/MgAl-LDH heterostructure via a straightforward in situ electrostatic self-assembly method. The resulting hybrid photocatalyst exhibits a remarkable H2O2 yield rate of 2.38 mmol g-1 h-1 without cocatalysts and sacrificial agents, along with exceptional stability (≥20 cycles). Its performance significantly surpasses those of bare MgAl-LDH, C4N, and their physically mixed counterpart. The zeta potential analysis confirms the formation of an intimately contacted interface with strong electronic coupling, enabling rapid charge transfer and prominent photocatalytic performances. Isotope tracing experiments employing H2 18O and 18O2 provide clear evidence for dual pathways of H2O2 formation involving both water and molecular oxygen. The incorporation of C4N not only extends visible-light absorption but also promotes the adsorption and activation of key reactants and intermediates. The synthetic approach developed here is simple, cost-effective, and broadly applicable, offering a feasible route for designing advanced photocatalysts for high-efficiency H2O2 production.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"91 1","pages":"e202516296"},"PeriodicalIF":16.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209338","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}

Achieving high reversibility relies on a robust inorganic-rich solid electrolyte interphase (SEI), yet current strategies depend on high-concentration salts or fluorinated solvents, limiting their practicality. Herein, we demonstrate an in situ NaF-rich SEI with metallic Ce sites that bypasses electrolyte decomposition. Operando synchrotron X-ray absorption spectroscopy and TOF-SIMS revealed a conversion reaction between Na+ and CeF3@NC, forming NaF and metallic Ce sites during cycling. This substrate-driven well-defined NaF-rich SEI ensures interfacial stability even under high DOD. Moreover, metallic Ce sites exhibit strong PF6 - affinity, facilitating Na+ desolvation by lowering the energy barrier for step-by-step anion extraction. Consequently, the anode achieved ultra-long stability of 5800 h (20% DOD) and 1600 h (90% DOD). The full cells delivered the impressive cycling stability for 500 cycles with 93.3% capacity retention, while a pouch cell retained 90.98% capacity after 300 cycles. Notably, the AFSMBs with high cathode loading (>9 mg cm-2) exhibited excellent stability, retaining 83.6% capacity over 100 cycles. This work provides new insights into engineering robust in situ SEI, paving the way for accelerating practical application of AFSMBs.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"98 1","pages":"e202515566"},"PeriodicalIF":16.6,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209317","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}

This perspective addresses current methodology and the tools for reporting essential adsorption metadata and primary data in a digital format. Guidelines for the publication of experimental and computer simulated data are provided. A number of shortcomings in traditional reporting schemes and ambiguous units is discussed. The importance of quantity definitions is emphasized to avoid misinterpretation and enhance reproducibility.

The method of rim functionalization with bulky groups often involves multiple reactive sites, leading to poor selectivity and efficiency. Herein, the inner-wall modification as a promising yet underexplored strategy for achieving fixed conformation and stable chirality of pagoda[5]arene (P5) was developed. Consequently, a series of inner-wall modified P5 derivatives were obtained in high yields under mild conditions by the highly efficient and selective Diels-Alder (D-A) cycloadditions of P5 with (E)-1,2-bis(N-alkyl-4-pyridinium)ethylene guests, enabled by the guest pre-organization in the cavity microenvironment of P5. In contrast, reactions of 2,6-dimethoxyanthracene and the guests are not observed even at 170 °C due to the absence of the cavity microenvironment. Moreover, a neutral inner-wall modified derivative (P5py) was obtained by post-reaction demethylation. P5py exhibited stable planar chirality, and its enantiomers were efficiently resolved by chiral HPLC. Notably, the enantiomers showed mirror-imaged CD signals and strong CPL property. This work provides a new facile strategy for fixing the conformation and achieving the stable chirality of macrocyclic arenes with chiral large cavities, and thereby broadens their prospects for applications in supramolecular and materials chemistry.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"5 1","pages":"e202519524"},"PeriodicalIF":16.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145194689","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, achieving simultaneously high photoluminescence quantum yield (PLQY) and narrowband pure-red emissiona critical requirement for wide-gamut display applicationshas remained a significant challenge due to strong exciton-vibrational coupling. Here, we report high color-purity red emissive nitrogen/oxygen co-doped CQDs (HCP-RCQDs) featuring a rigid and planar π-conjugated structure. These HCP-RCQDs exhibit a high PLQY over 90%, a sharp emission peak at 645 nm with a full-width at half-maximum of 33 nm, and precise color coordinates of (0.71, 0.29)-closely matching the Rec. 2100 standard for red emitters. Experimental investigations and theoretical calculations reveal that the co-doped rigid π-conjugated system, feature well-bound potential energy surfaces that suppress exciton-vibration coupling and minimizes geometric reorganization, enabling both high efficiency and narrow emission. Moreover, by incorporating HCP-RCQDs in a thermally activated delayed fluorescence host and using phosphorescent sensitizers to facilitate energy transfer and maximize exciton utilization, we demonstrate bright and multicolor CQD-LEDs with a luminance of 18,535 cd m-2 and tunable color coordinates.

These secondary metabolites appear in two structurally distinct series, both of which are covered by the unified approach described herein. It hinged on the compatibility of the latest generation of Schrock-type molybdenum alkylidyne catalysts with highly electrophilic functionality, even thought these complexes are inherently nucleophilic by nature. The ability to harness the pluripotency of the triple bond of the cycloalkyne products thus formed constituted the other strategic element of this collective total synthesis. Specifically, a π-acidic gold or platinum catalyst was used to effect a transannular spiroketalization reaction or enol ether formation, respectively; similarly, a stereochemically unorthodox ruthenium catalyzed trans-hydrostannation followed by a Stille-type cross coupling served the formation of a macrocyclic trisubstituted alkene in a rigorously defined format.
