Herein, we report a synergistic relay strategy that integrates phenoxyl-radical-mediated oligomerization and aromatic-ring-opening pathways for the highly efficient treatment of organic wastewater. This approach couples an initial high-valence iron-oxo species (HVIO)-driven oligomerization via formal hydrogen atom transfer at one site with a subsequent singlet oxygen (1O2)-mediated ring-opening reaction at an adjacent site, enabled by a dual-single-atom Fe1Cu1/TiO2 photocatalyst. Under solar-light irradiation, photoinduced electrons are transferred to peroxymonosulfate (PMS) at the Fe1 site, which acts as a critical activator to generate HVIO for oligomerization-based removal. Simultaneously, holes oxidize PMS at the Cu1 site to produce 1O2, leading to efficient aromatic-ring-opening. This sequential strategy achieved nearly 72% chemical oxygen demand removal with 23% carbon recovery into separable polymer products within 10 min for the phenol and ultimately reached complete removal with a rate constant of 1.21 min−1, significantly surpassing most reported values. Moreover, the system exhibited excellent stability and long-term activity in a custom-designed photo-filter reactor, highlighting its practical potential. By coupling oligomerization and mineralization, this work provides a groundbreaking and versatile platform for treating complex organic wastewater.\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its electrochemical performance is severely compromised by the formation of electrochemically inactive maricite NaFePO4 (m-NFP) during synthesis. Here, we induced the in situ formation of a Na3.12Fe2.44(P2O7)2 (N3.12F2.44PO) phase within NFPP through stoichiometry engineering to construct a heterogeneous composite. This strategy effectively suppresses m-NFP formation and improves reversible capacity, while retaining the intrinsic cost advantage of NFPP without incorporating additional elements or extra synthetic steps. The optimized NFPP/N3.12F2.44PO heterostructure exhibits remarkable structural robustness, with the P2O7-rich N3.12F2.44PO phase acting as a structural buffer to mitigate lattice deformation, enabling an ultralong cycling life of 10,000 cycles at 40C (1C = 129 mA g−1) with 83.6% capacity retention. By mapping phase evolution across a controlled Na-Fe-P compositional window, we further reveal that Na and Fe contents govern the formation propensity of the N3.12F2.44PO phase, offering a viable route to heterogeneous NASICON-type cathodes with exceptional cycling durability for sodium-ion batteries.\u0000 </div>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by station-regulated shuttling in molecular machines, we introduce mechanically gated “speed bumps” into SR architectures. Here, we report a mechanically interlocked polyurethane network PU-DP-TED-a, in which pillar[5]arene-based macrocycles (DP) function as sliding crosslinkers and strategically positioned Diels–Alder adducts (TED) act as force-labile speed bumps along the polymer axle. Under tension, macrocycles are pushed against TED units, triggering a retro-Diels–Alder reaction that transiently arrests ring sliding and dissipates mechanical energy. This force-triggered, sequential “arrest-and-release” mechanism provides spatiotemporal control over energy dissipation. Relative to a non‑interlocked control containing TED but no DP, the resulting material exhibits a rare combination of enhancements: Young's modulus increases by 9.9‑fold (from 3.46 to 34.2 MPa), tensile strength by 6.0‑fold (from 3.28 to 19.8 MPa), elongation at break by 2.9‑fold (from 155% to 449%), and toughness by 16.6‑fold (from 3.74 to 62.0 MJ m−3).

Driven by the urgent clinical demand to overcome the inherent pharmacological liabilities of biomolecules, the field is undergoing a decisive Peptide-to-Small Molecule paradigm shift—functionally converting peptide-derived recognition motifs into orally bioavailable synthetic therapeutics. This Perspective highlights how foundational geometric design principles—linear repetition, convergent fusion, and cyclization—define next‑generation architectures capable of targeting complex protein–protein interactions (PPIs). Repeating‑unit oligomers exemplify linear projection strategies, heterocycle‑centered scaffolds embody the convergent fusion of recognition motifs, and macrocyclic frameworks pre-organize bioactive conformations while enabling access to non‑canonical topologies. Beyond simple mimicry, these architectures increasingly embrace dynamic responsiveness, aggregation remodeling, and universal multi‑structure platforms. We argue that the convergence of geometric logic with automated synthesis and AI‑driven design will transform peptidomimetics into a primary modality for decoding and therapeutically engaging the human interactome, including historically “undruggable” PPIs.","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"138 40","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ange.4236524","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149068429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TQAC was constructed through a macrocycle-to-cavitand conversion by incorporating electron-deficient quinoxaline panels into an electron-rich acridine-based macrocyclic scaffold, giving rise to an intramolecular donor–σ–acceptor framework and pronounced charge-transfer luminescence. Depending on the crystallization conditions, TQAC forms two solid-state polymorphs with distinct conformations and packing modes, affording porous TQACα and interlocked TQACβ, which emit yellowish-green and orange fluorescence, respectively. Notably, both polymorphs exhibit two-photon-excited emissions, making TQAC the first solid-state cavitand system showing dual-color two-photon-absorption property. Moreover, the guest-accessible TQACα phase displays rapid and visually distinguishable fluorescence responses toward benzene and pyridine vapors, with detection limits of 7.5 and 3.3 mg L−1, respectively.
