These were obtained by abstracting the solvent molecules from the potassium atoms of the corresponding monomers [Ln(η5-LSn)2K(thf)4]. The flexible coordination of the stannole dianion enables polymerization via potassium-mediated Sn–K–arene interactions, yielding linear chain structures while preserving a highly axial coordination environment around the Ln3+ center. Magnetic studies reveal that both [Ln(η5-LSn)2K]n (Ln = Tb, Dy) compounds behave as single-molecule magnets in zero field, with significantly enhanced performance compared to their monomeric analogues. In particular, [Dy(η5-LSn)2K]n exhibits an increased effective energy barrier of Ueff = 1812 K, representing an improvement of ∼20%, alongside suppressed quantum tunneling of magnetization and slower relaxation dynamics. Detailed analysis of the relaxation mechanisms indicates that polymerization reduces spin–phonon coupling, as evidenced by a marked suppression of the Raman relaxation process, despite softer lattice vibrational modes. Ab initio calculations confirm the retention of highly axial electronic structures. These results demonstrate that assembling axial lanthanidocenate units into one-dimensional frameworks is an effective strategy to enhance magnetic anisotropy and control relaxation pathways, providing a route to mitigate relaxation in high-performance lanthanide-based single-molecule magnets.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"45 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221795","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}

Here, we identify a widespread group of rSAM enzymes associated with type III/IV lanthipeptide gene clusters through combined genome mining and phylogenetic analysis. Characterization of representative pathways uncovered a series of new lanthipeptides bearing an N-terminal aromatic–proline carbon–carbon cross-link. Detailed LC–MS/MS and NMR analyses revealed that Trp, Phe, or His residues are covalently linked to a conserved Pro residue, establishing a broader family of rSAM-catalyzed aromatic–proline couplings in lanthipeptide biosynthesis. Notably, biochemical reconstitution, active-site mutagenesis, substrate profiling, and isotope-labeling experiments define key catalytic requirements, support a radical-mediated dehydrogenative coupling mechanism, and show that lanthionine formation is not an absolute prerequisite for AitR-catalyzed aromatic–proline cross-linking.

Donor–acceptor two-dimensional covalent organic frameworks (COFs) are widely used to promote charge separation, but the role of directional charge transport in these layered materials is still not well understood. Here, we combine photophysical characterization and time-dependent density functional theory calculations to study three TAPD-based COFs for photocatalytic H2O2 production via oxygen reduction. All materials show efficient in-plane donor–acceptor charge transfer with similar exciton dissociation behavior. At the same time, clear differences appear in their charge transport properties. The calculations indicate that electrons move preferentially along the stacking direction, while holes remain more delocalized within the COF plane. This anisotropic transport is most pronounced in the COFs where stronger interlayer coupling favors the formation of interlayer charge-transfer states, as observed in transient absorption measurements. These states allow electrons and holes to separate over adjacent layers, which reduces recombination losses and corroborates the observed differences in photocatalytic activity. Our results indicate that directional interlayer charge transport, rather than local donor–acceptor charge separation alone, is an important factor in determining photocatalytic performance in COFs.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"88 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221790","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 an effective strategy to balance this trade-off in the selective hydrogenation of nitroarenes by employing surface hydrogen–oxygen pulse titration under an oxidative atmosphere to initiate nonsteady-state oxidative modulation of Pt/CeO2 coordination. Thermochemical analysis and DFT calculations reveal that the pulsed treatment induces a transient exothermic process, driving the oxidation and structural fragmentation of Pt nanoparticles and gradually leading to the formation of isolated Pt1 single atoms. Atomic-resolution electron microscopy and quasi in situ X-ray spectroscopy further demonstrate that, unlike conventional thermodynamic treatments, this transiently induced evolution results in tunable coordination environments (from nanoparticles to single atoms) of central Pt atoms. In this structural transformation, the constructed Pt1–O2 single-atom sites on the CeO2 surface, with an average Pt oxidation state of ∼+0.9, not only enable preferential adsorption and activation of the nitro group while suppressing undesired hydrogenation of other reducible functionalities (e.g., C═C group) but also retain high H2 activation capability. As a result, the traditional activity–selectivity seesaw is shifted toward an optimized balance, affording outstanding performance in the selective hydrogenation of 4-nitrostyrene (2143 h–1 turnover frequency, 96% selectivity), as well as excellent substrate adaptability (10 types of substrates). This study offers new insights into coordination environment engineering via transient treatments and provides a general approach for the rational design of high-performance catalysts in complex hydrogenation reactions.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"12 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221774","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}

The optimized In7Zr3Ox catalyst exhibits >95% selectivity toward ortho-methylation with tunable product distribution, ranging from 92% o-cresol at 16% conversion to 86% 2,6-xylenol at 97% conversion, while maintaining stable operation for 140 h.

This pathway exhibits a markedly lower apparent activation energy of 58.8 kJ mol–1 than the conventional methanol-mediated route of 116.3 kJ mol–1.

Current understanding for acylhydrazide installation is limited to a “hydrazine-first” strategy, wherein an activated acyl donor is nucleophilically attacked by a preassembled hydrazine intermediate. Spinamycin, an antifungal hydrazide-containing aryl polyene from Streptomyces albospinus, challenges this convention. Its biosynthetic machinery utilizes SpiA7, an ATP-dependent, nitrite-utilizing N-nitrosylase, to synthesize a highly transient diazo intermediate rather than a hydrazine core. How this unstable diazo compound is converted into a stable hydrazide has remained a long-standing biosynthetic mystery. Herein, we report the in vitro reconstitution of the activity of SpiA7 in conversion of the amine substrate into its mature succinylhydrazide form. Mechanistic characterization revealed that the electrophilic diazo intermediate is initially captured by thiol reagents to generate a covalent azo-sulfide intermediate (R–N═N–S–R′). This species likely undergoes a noncanonical four-electron reduction driven cooperatively by disulfide bond formation and the oxidative decarboxylation of α-ketoglutarate (αKG), which serves as the succinyl donor. Furthermore, site-directed mutagenesis identifies Cys453 of SpiA7 as a likely active-site thiol donor orchestrating this transformation. Collectively, our findings unveil an unprecedented chemical strategy for hydrazide assembly that completely bypasses a free hydrazine intermediate, expanding nature’s known catalytic repertoire for building complex N–N linkages.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"1 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221794","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}

In particular, protonation at the S2B site imparts lability that facilitates substrate binding and may enable this sulfide to act as a proton donor. Although FeMoco is inactive outside its protein environment, how secondary-sphere residues tune its geometric and electronic structure to enable function remains unclear. We have previously shown that site-selective Se substitution of the μ2-sulfides provides a direct probe of the ligand environment using Se K-edge high-energy-resolution fluorescence-detected X-ray absorption spectroscopy (HERFD XAS). Despite the cofactor’s approximate C3 symmetry, Se-substituted sites display pronounced differences in Se HERFD XAS pre-edge intensities. Utilizing QM/MM calculations, we show that hydrogen-bonding (H-bonding) residues polarize the S3A and S5A sulfides, reducing metal–ligand covalency and attenuating pre-edge intensity, whereas hydrophobic residues surrounding S2B localize electron density and enhance its pre-edge intensity. These results demonstrate how hydrophobicity and H-bonding within the secondary coordination sphere modulate FeMoco electronic structure. More broadly, they show how the protein environment tunes ligand basicity to favor selective S2B protonation and provide design principles for controlling enzymatic function.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"62 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221779","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, their deeply desodiated frameworks at high voltages (≥4.0 V) are prone to redox-coupled distortion of TMO6 octahedra within the transition metal (TM) slabs, leading to severe structural degradation. Here, we originally define an ionic field strength disparity coefficient (η), which enables quantitative evaluation of the local chemical-field heterogeneity. The η is derived from the ratio between the standard deviation and the average value of ionic field strength (Φ) of all TM ions, defined as Φ= Z/r2, where Z and r correspond to the ionic charge and ionic radius, respectively. Introducing compensatory cations with an intermediate Φ value between two cations featuring largely disparate Φ values effectively reconciles local chemical-field discrepancy and lowers the η parameter upon charge–discharge processes. Moreover, synchrotron X-ray absorption spectroscopy, strain mapping analyses, and first-principles calculations reveal that the low-η sample demonstrates the reduced lattice strain and enhanced structural reversibility. Consistently, electrochemical evaluation shows that it retains more than 80% of its capacity after 500 cycles at 10C, markedly outperforming the unmodified counterpart with only 22% retention. This work establishes the η as a quantitative descriptor for inactive dopant selection and provides a general strategy for developing highly stable layered oxide cathodes.","PeriodicalId":49,"journal":{"name":"Journal of the American Chemical Society","volume":"2 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2026-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149221792","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}
