However, singlet oxygen (1O2), often underappreciated, plays a pivotal role in H2O2 production. Meanwhile, photocatalytic biomass conversion has attracted attention, yet studies combining H2O2 synthesis with biomass valorization remain rare and typically yield low-value products. Herein, we report a strategy of photocatalytic valorization of furfuryl alcohol (FFA) coupled with the efficient co-production of H2O2, enabled by covalent organic frameworks (COFs) induced, 1O2-participated Achmatowicz rearrangement. This study introduces polyimide-based COF-N0-3 with tailored nitrogen content, representing an unprecedently efficient platform for 1O2 production. Remarkably, reducing the nitrogen content of the COF enhances 1O2 production, significantly boosting the H2O2 generation rate. In FFA, the primary pathway for H2O2 production is Achmatowicz rearrangement, achieving a rate ten times higher than that reliant on oxygen reduction reaction in pure water, reaching 4549 μmol g⁻¹ h⁻¹. Mechanism studies revealed 1O2 selectively engaged FFA, bypassing hole oxidation to trigger the Achmatowicz rearrangement, producing valuable 6-hydroxy-(2H)-pyranone with 99% conversion and 92% selectivity. This work establishes a coupling strategy for simultaneoues synthesis of H2O2 and biochemicals, offering a transformative approach to sustainable photocatalysis.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"29 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539094","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}

Natural photosynthesis exemplifies an ingenious approach for carbon neutrality, converting CO2 into O2 and glucose through light and dark reactions. Inspired by the hydrogen-involved processes in photosynthesis, we present an aprotic electrochemical strategy for CO2 splitting into O2 and carbon using lithium as a reducing mediator. The designed electrochemical device features a gas cathode with nanoscale Co catalyst and a metallic lithium anode. When CO2 is introduced to the cathode, it undergoes a two-step lithium-related electrochemical reduction, converting it sequentially into Li2CO3 and Li2O. Li2O is then oxidized to produce O2 gas at the expense of renewable electrical energy. This process achieves an impressive O2 yield exceeding 94.7%, significantly outperforming the efficiency of natural photosynthesis. Moreover, the O2 yield can be further increased to 98.6% by employing an optimized RuCo catalyst. Our study offers a new practical and controllable pathway to produce O2 from CO2, strongly promoting the sustainable development of human society for realizing carbon neutral as well as exploring and conquering nature.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"23 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539272","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}

Herein, a series of six-membered cyclic carbonate monomers with different alkyl α-substituents were synthesized using CO2 and bioderived 1,3-alkanediol as raw materials at room temperature and atmospheric pressure. The organocatalytic ring-opening polymerization was systematically studied using a range of common and readily available organocatalysts. Phosphazene base (t-BuP2) was identified as the most effective catalyst, offering excellent control over the entire polymerization. The regioselectivity of the synthesized polycarbonates, ranged from 0.74 to 0.99, with the highest value achieved when the side group was isopropyl (highest steric hindrance). Notably, the α-substituent in the mono-mers reduced the ring strains, allowing the resulting polycarbonates to be fully recycled to the monomers without decarboxylation. The recycling process effectively traps CO2 in a closed loop between monomers and polymers, preventing its release into the atmosphere. The alkyl side groups enhanced the hydrophobicity of the polycarbonates, thereby reducing the likelihood of CO2 release through hydrolysis during their lifecycle, achieving a robust CO2 closed-loop fixation. The utility of CO2-APCs as adhesives and the ability of copolymerization with L-lactide (L-LA) were explored.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"67 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546994","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}

However, the reported Y-GMAs all use a single-typed linking site, making it difficult to finely-tune their optoelectronic properties. Herein, we develop a non-fully conjugated Y-GMA (named 2Y-we), with hybrid linking sites at the wing and end-group of monomers, to combine the respective advantages of the wing and end-group site linked counterparts. Compared to its parental monomer, 2Y-we shows different intermolecular interaction, crystallinity, packing, and glass transition temperature, allowing optimized active layer morphology (including appropriate phase separation and ordered molecular packing) and stability. Consequently, the D18/2Y-we-based organic solar cells (OSCs) obtain an improved power-conversion-efficiency (PCE) of 17.4% with both higher open-circuit voltage (VOC) and short-circuit current density (JSC), due to the reduced energy loss and efficient exciton dissociation. Inspired by its high VOC×JSC, 2Y-we is introduced into D18:L8-BO to fabricate ternary devices. Thanks to the further optimized morphology and improved charge transport, the ternary OSCs achieve a superior PCE of 19.9%, which is the highest value among the reported non-fully conjugated Y-GMAs.

While considerable efforts have focused on reducing ΔES1T1, investigations on SOCs remain limited. Here, we propose blocking π-conjugation in carbonyl-embedded polycyclic heteroaromatic (PHA) molecules as potential approach to elevate ππ* excitation energy, allowing its hybridization with nπ* excitation, thereby increasing SOCs. We synthesized two proof-of-concept isomers, DNDK-1 and DNDK-2, with different orientations of carbonyl units. DNDK-1 adopts heavily twisted structure that hinders π-conjugation, while DNDK-2 remains quasi-planar, maintaining stronger π-conjugation. Experimental measurements revealed stark differences in their photophysical properties, with DNDK-1 exhibiting faster kRISC and much higher electroluminescence efficiency. The ab-initio calculations elucidate that hindered conjugation in DNDK-1 elevates ππ* excitation energy, enabling nπ*-ππ* mixing, thus significantly boosting SOCs. In contrast, smooth π-conjugation in DNDK-2 leads to marginal nπ*-ππ* mixing. In addition, utilizing groups composed of meta-arranged carbonyl-Ar-carbonyl and meta-arranged N-Ar-N units emerges as another approach to block π-conjugation and enhance SOCs. This joint experimental and theoretical work provides promising pathways to enhance SOCs by blocking π-conjugation, offering crucial insights for designing carbonyl-embedded PHA emitters with larger SOCs.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"52 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539024","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}

Detailed structure characterizations demonstrate the controllable construction of Pd single-atom and Pd ensemble sites modified Cu surfaces and PdCu alloy via fine tuning the Pd/Cu ratios. Catalytic tests, kinetics analysis, and temperature-programmed experiments demonstrate that the presence of Pd ensemble sites on Cu surface directly catalyzes the hydrogenation of propyne that occurs on the Cu sites in other cases, and enables a facile activation for hydrogen and simultaneously promotes the desorption of propylene against its hydrogenation. Accordingly, the selectivity to target propylene is up to 95.3% at the full conversion of propyne on the corresponding Pd0.1Cu catalyst. In contrast, the C-C coupling pathway is quite facile on the Cu surface tuned by single-atom Pd sites, which is similar to that on the pristine Cu sites on the Cu catalyst, and the well-defined Pd-Cu coordination on PdCu alloy catalyst leads to facile over-hydrogenation process.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"22 1","pages":""},"PeriodicalIF":16.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539181","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}
