However, the uniform reactivity of conventional high-symmetry ligands typically leads to homogeneous linking, limiting the programmable construction of diverse topologies and metal nodes from a single-type ligand. Here we report an anisotropic reticular chemistry strategy using the 1,2,5,6,9,10,12,13-octahydroxydibenzo-[fg,op]naphthacene ligand with diverse catechol reactivities to construct seven distinct c-MOF crystals. Site-selective coordination of 1,2,5,6,9,10,12,13-octahydroxydibenzo-[fg,op]naphthacene yields three topologically distinct copper-based c-MOFs, including 2D square-arranged (Cu-2D-sql), 2D honeycomb-arranged (Cu-2D-hcb) and one-dimensional linear (Cu-1D) structures. Cu-1D could further react with metal ions to produce four bimetallic CuM-2D-sql (M = Ni, Co, Zn or Mn) with defined bimetal node arrangements. Theoretical modelling and single-crystal electrical measurements reveal that this structural programming effectively modulates the charge transport behaviour. The anisotropic reticular chemistry strategy thus provides a route towards atomic-level control over the structures and electronic properties of conductive frameworks.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149039930","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}

Unactivated N-alkyl aziridines have long resisted ring opening and cross-coupling, so the installation and removal of N-activating groups followed by N-alkylation remains the most applicable route for aziridine diversification. Here we report a general radical activation mode that directly engages N-alkyl aziridines in ring-opening and divergent functionalization. Coordination of BH3 generates stable aziridine-ligated borane complexes that are selectively converted into aziridine-ligated boryl radicals. These species undergo regioselective β-scission to form β-aminoalkyl radicals that can be intercepted in metal-catalysed cross-coupling reactions. Two complementary platforms were developed: an oxidative copper catalytic system engaging aryl boronic acids, as well as nitrile and sulfide nucleophiles, and a dual photo–nickel catalytic system for cross-coupling with electrophilic aryl bromides. Together, these results establish a general strategy to directly engage N-alkyl aziridines in divergent ring opening and functionalization, thus streamlining access to β-functionalized amines. Aziridine ring opening is a powerful strategy for molecular diversification, but direct functionalization of unactivated N-alkyl aziridines has remained a long-standing challenge. Now it has been shown that aziridine-ligated boryl radicals enable direct ring opening and divergent functionalization of N-alkyl aziridines, providing streamlined access to diverse β-functionalized amines.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":"18 10","pages":"1755-1762"},"PeriodicalIF":24.5,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.comhttps://www.nature.com/articles/s41557-026-02247-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149021938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, a small-molecule walker that combines autonomy with kinetic asymmetry has so far proven elusive. Here we show that simple phosphoric acid esters enable a non-enzymatic reaction cycle that drives the migration of a phosphate group along molecular tracks bearing hydroxy footholds. Carbodiimide fuel transiently generates cyclic phosphodiesters, which undergo selective hydrolytic ring opening to advance the walker. On a glycerol track, the walker reaches a non-equilibrium steady state sustained for several hours, while an extended inositol scaffold supports autonomous migration across five alcohol sites. Modelling reveals the ability of the walker to differentiate the centre of the track from its ends. By introducing migratory endergonic synthesis on biologically relevant phosphate scaffolds, this work expands the scope of synthetic molecular machinery.","PeriodicalId":18909,"journal":{"name":"Nature chemistry","volume":" ","pages":""},"PeriodicalIF":24.5,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149002343","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}
