However, the regioselective synthesis of unsymmetrical vicinal diamines from unactivated alkenes remains a long-standing challenge. Herein, we report an iron-photocatalyzed ligand-to-metal charge-transfer (LMCT) strategy that enables the simultaneous generation of two nitrogen-centered radicals with distinct reactivities, allowing unsymmetrical diamination of alkenes under mild, additive-free conditions. The method features broad substrate scope, excellent regioselectivity, and compatibility with complex bioactive molecules, opening new avenues for late-stage amine diversification and drug discovery. Mechanistic studies suggest that an <i>in situ</i> Fe(III)-α-amido-oxy acid complex acts as the photoactive species, LMCT triggers O-centered radical formation, followed by decarboxylation/deacetonylation to generate an amidyl radical, which adds to alkenes and undergoes Fe-mediated azidyl transfer to afford unsymmetrical vicinal diamines.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":772,"journal":{"name":"Science China Chemistry","volume":"69 9","pages":"5178 - 5187"},"PeriodicalIF":9.8,"publicationDate":"2026-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148986720","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 review focuses on the design principles, entropy-stabilization mechanisms, and electrochemical functionalities of high-entropy cathodes for ARBs. Representative material systems, including Prussian blue analogues, high-entropy oxides, polyanionic compounds, and catalytically active cathodes, are critically discussed across various charge carriers.

However, the rotation of C–C single bonds in these acceptors causes weak intermolecular interactions and low charge mobility, restricting further improvement of their power conversion efficiency (PCE). In this study, we designed and successfully synthesized three isomeric NFREAs. By regulating oxygen atom positions in side chains, we modulated intermolecular interactions, optimized thin-film morphology, and enhanced charge transport capability. Experimental results showed that molecular crystallinity gradually decreased with the outward shift of oxygen atoms. Among them, BTh-O-2 exhibited a higher molar extinction coefficient and moderate crystallinity, along with good miscibility with polymer donor D18. Its blend film presented an ideal fibrous network microstructure, ultimately achieving a PCE of 17.11%. Its blend film exhibited an ideal fibrous network morphology, with optimal charge transport and minimized charge recombination in the device. Consequently, the device based on D18:BTh-O-2 achieved a PCE of 17.11%. This achievement ranks among the highest efficiencies reported so far for OSCs based on NFREAs.
