Transient IR absorption spectroscopy reveals that 2D layered materials like Bi₄NbOCl rarely form such traps. This is due to the formation of a defect-tolerant, bonding-based conduction band minimum, which effectively suppresses deep traps while maintaining high electron reactivity. Addressing this issue has been a major focus in photocatalysis research, as reported by Akira Yamakata, Takafumi Ogawa, and Hiroshi Kageyama et al. in their Research Article (e202419624).\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":7803,"journal":{"name":"Angewandte Chemie","volume":"137 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ange.202505560","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688992","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}

However, developing molecular design strategies to achieve both high efficiency and mechanical robustness in IS-OSCs remains a significant challenge. In this work, we present a novel approach by synthesizing a dimerized electron acceptor (DY-FBrL) that enables rigid OSCs with a high power conversion efficiency (PCE) of 18.75 % and a crack-onset strain (COS) of 18.54 %. The enhanced PCE and stretchability of DY-FBrL-based devices are attributed to its extended π-conjugated backbone and elongated side chains. Furthermore, we introduce an innovative polymerized acceptor (PDY-FL), synthesized via the polymerization of DY-FBrL. While PDY-FL-based devices exhibit a slightly lower PCE of 14.13 %, they achieve a significantly higher COS of 23.45 %, representing one of the highest PCEs reported for polymerized acceptors containing only flexible linkers. Consequently, IS-OSCs fabricated using DY-FBrL and PDY-FL achieve notable PCEs of 14.31 % and 11.61 %, respectively. Additionally, the device stretchability improves progressively from Y6 (strain at PCE<sub>80%</sub>=11 %), to DY-FBrL (strain at PCE<sub>80%</sub>=23 %), and PDY-FL (strain at PCE<sub>80%</sub>=31 %).
