However, a significant challenge limiting the implementation of visible-light-activated polymerizations is its low efficiency compared to UV light driven processes. To address this, we developed a series of visible-light-activatable organoboron (BOSHY) complexes featuring salicylaldehyde azine ligands for rapid cationic polymerization. These BOSHYs featuring different brominated BOSHY catalyze the polymerization of epoxides under 405 nm LED light in three-component systems with iodonium salt and amine, achieving a 78% epoxy conversion in just 52 s at low intensity irradiation of 50 mW cm<sup>-2</sup>. Additionally, the mechanism of photopolymerization involves the formation of cations by EDB, which initiates the polymerization process. The triplet state lifetime (15.4-23.5 μs) indicates effective intersystem crossing, enabling efficient energy and electron transfer reactions. Experiments confirm nearly 100% electron transfer due to the extended triplet state lifetime. This study not only introduces novel BOSHY derivatives for cationic polymerization but also elucidates the reaction kinetics analysis of the photopolymerization, significantly expanding the use of visible light LEDs as an alternative to UV light in photopolymerization.</p>","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144558433","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}

However, it is difficult for existing catalysts to exhibit bifunctional high-current activity in the same electrolyzer, considering that the bimetallic site can endow the catalytic material asymmetry and heterogeneity and then change the intrinsic electronic structure. Herein, we constructed a La-Fe dual-site coupled self-assembled membrane electrode (D-LaFe-SAME), and the introduction of the dual site reduced the Bader charge value of the La site from 0.87 to 0.83|e|, while the Bader charge of the Fe site increased from 0.69 to 0.70|e|, thus optimizing the Bader charge value of La-Fe active sites to a close equilibrium. Consequently, the free energy barrier of the rate-determining step is optimized, and the catalytic activity is greatly improved. Prominently, the optimal D-LaFe-SAME can achieve current densities of up to 2000 mA cm-2 at very low overpotentials (-640 mV for HER and 626 mV for OER), which is even better than the commercial precious metals Pt/C and IrO2. Surprisingly, when we use a large area of D-LaFe-SAME for overall water splitting, it can operate stably at currents up to 4 A. The dual-site coupled strategy based on the Bader charge balance mechanism proposed in this work is crucial for the construction of an efficient and high-current electrocatalytic system for hydrogen production in the same electrolyzer and plays a key role in achieving the goals of carbon neutrality.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"28 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144547751","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}
