Dearomatization of indoles has emerged as a particularly powerful strategy for accessing these three-dimensional, highly functionalized scaffolds from readily available aromatic precursors. In this context, photochemical activation has opened new avenues for indole dearomatization by harnessing the distinctive reactivity of electronically excited states and enabling bond-forming processes that are often difficult to achieve under conventional thermal conditions. This review highlights recent advances in excited-state dearomatization of indole, with the discussion organized into intramolecular and intermolecular transformations.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"15 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various cathodes, layered δ-MnO2 is particularly attractive because of its open framework, favorable Zn2+/H+ storage kinetics, and high charge-storage capability. However, practical implementation is hindered by Mn dissolution, hydrogen evolution, surface by-product formation, structural degradation, and irreversible phase transformations associated with complex Zn2+/H+ storage and interfacial reactions. Unlike previous reviews of MnO2-based AZIBs, this review establishes a δ-MnO2-specific structure–mechanism–stability framework, linking its layered structure and interlayer chemistry with ion storage, structural evolution, and degradation. This work also considers mechanistic insights from DFT calculations and advanced characterization techniques, which help elucidate ion-storage pathways, interfacial reactions, phase transformations, and structural degradation. Recent strategies including nanostructuring, defect engineering, doping, interlayer and interface modification, and composite design are critically evaluated from a structure–property–performance perspective. Beyond materials optimization, a materials-to-device perspective is established by addressing high-mass-loading electrodes, areal capacity, cell-level energy density, pouch-cell configurations, scalability, sustainability, and commercialization. Finally, key design principles and emerging research directions are proposed to guide the development of durable, scalable, and commercially relevant δ-MnO2-based AZIBs toward 2030.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"19 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149374967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
