Here, we introduce a topological confinement strategy that generates a previously inaccessible class of open‑shell species: neutral soliton‑type radicals, within amidine‑linked oligoacetylene networks. In chemical terms, these species are characterized by a delocalized spin density over the conjugated backbone, distinguishing them from conventional localized radicals. These materials exhibit a distinct axial g ‑tensor, Curie behavior, and broad near‑infrared absorption extending to 1000 nm. Unlike conventional photothermal systems, where heat originates from exciton transfer energy to the lattice via nonradiative processes, our system stores light energy in long‐lived soliton states that dissipate via lattice vibrations, producing no ground‑state bleach yet enabling efficient heat generation. Using this mechanism, the materials drive aldehyde‑indole coupling under mild light irradiation through a photothermal catalytic pathway. More broadly, this work translates soliton physics into a synthetic materials platform for spin‑functional materials.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"10 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172728","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 show that this apparent quiescence is accompanied by a heightened vulnerability to electron transport chain (ETC)‐associated perturbation by guanidinium‐based cationic polymers. PO 3 G, a representative polymer, preferentially kills persister‐enriched populations while markedly perturbing respiratory electron transfer. Following this ETC‐associated perturbation, persister‐enriched populations exhibit sustained superoxide‐associated oxidative stress and fail to restore NADH/NAD + homeostasis, leading to progressive loss of viability. Consistent with this ETC dependency, PO 3 G also markedly reduces persister‐enriched population induced by diverse triggers across bacterial species and achieves up to 7‐log reductions in bacterial burden in vivo. These results establish a mechanistic link between cationic polymer‐induced ETC‐associated perturbation and persister elimination, highlighting limited recovery from respiratory and redox perturbation as a vulnerability underlying the preferential killing of persisters.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"59 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172725","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}

H‑aggregates promote triplet formation and charge transfer, but often suffer from substantial absorption blueshifts and excessive thermal deactivation that compromise photosensitization efficacy. Herein, a hierarchically molecular programming strategy is proposed to construct minimal‐blueshift H‐aggregates as robust NIR type I photosensitizers. Primary engineering via π‐bridge extension and acceptor strengthening within a twisted–planar donor–π–acceptor scaffold endows the antiparallel H‐packed TNCF3‐C6‐C2 aggregates with strong NIR absorption (749 nm) and predominant type I ROS generation. Secondary side‐chain programming further regulates the H‐packing and intermolecular electronic interactions to enhance type I ROS generation. Structural, photochemical and theoretical investigations revealed that the branched side chains promote molecular planarization and robust H‑packing, thereby enhancing intersystem crossing and intermolecular charge transfer. The optimized TNCF3‐2C6 with symmetric branched side chain exhibited minimal absorption blueshift (20 nm) upon H‐aggregation, enhanced NIR harvesting ability and a further ∼2‐fold enhancement in ROS generation over the initial TNCF3‐C6‐C2 H‐aggregates, thereby delivering potent tumor inhibition both in vitro and in vivo. Built upon the hierarchical programming of H‐aggregates, this work establishes a supramolecular design paradigm toward modulating excitonic coupling and excited‐state dynamics for high‐performance photo‐functional materials.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"53 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172726","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 report an architectural strategy that uses Na 2 O/Na 2 CO 3 heterointerfaces as local nanoionic transport units and organizes them into a bulk‐distributed, three‐dimensional network throughout a preformed electrode. This architecture is realized by coupling ultralow‐flux Na‐vapor metallization with mesopore‐regulated gas‐solid conversion in a preformed metal‐organic framework (MOF) host. The synergy of space‐charge carrier enrichment and MOF‐mediated lattice distortion simultaneously boosts carrier density and lowers migration barriers, yielding an estimated local interfacial conductivity on the order of 10 −7 S cm −1 at 25°C, from intrinsically insulating Na 2 O (10 −12 S cm −1 ) and Na 2 CO 3 (10 −23 S cm −1 ). Integrated with conducting carbon, this functionally percolating network enables stable solid‐state presodiation and ultrahigh‐rate sodium‐ion full cells. This work bridges the gap between nanoscopic interface physics and macroscopic device functionality, identifying the spatial connectivity of phase boundaries, rather than the localized space‐charge effect alone, as a programmable design variable for next‐generation solid‐state ionics.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"27 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2026-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149172727","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}
