The success of this three-component reaction is attributed to the in situ generation of an active 1-(2-chloroethyl)-1,4-diazabicyclo[2.2.2]octan-1-ium (DABCO·DCE) salt, which judiciously acts as a formal N-(2-chloroethyl)piperazine equivalent in the defluorinative coupling with less-studied aliphatic fluorinated substances. Impressively, this reaction accomplishes multi-activation of robust C(sp3)-F, C(sp3)-Cl, C(sp3)-O, and C(sp3)-N bonds in a one-pot process, offering a practical platform for the late-stage functionalization of complex molecules. Furthermore, the resulting products can not only serve as versatile building blocks for the synthesis of fluorinated heterocycles, but also undergo C—Cl bond displacement transformations with N-, O-, and S-nucleophiles.\u0000 \u0000 \u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"43 4","pages":"378-384"},"PeriodicalIF":5.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115259","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}

Due to the variety, complex sources, similar appearance and shape, it is difficult to distinguish FCB with high curative effect (h-FCB) from other common fritillarias (c-FCB) in the market. In this paper, a very simple chemiresistor is used to identify FCB from three commonly used fritillarias drugs. The sensors are fabricated by anisotropic electrically conductive metal-organic framework (cMOF) thin film Cu3(HHTP)2 (Cu-HHTP[001] and Cu-HHTP[100]) as active materials owing to their ability to detect specific groups of volatile organic compounds (volatolomics) as the functional motifs of chemiresistor. As a result, the sensors show orientation-dependence identification ability to FCB. Cu-HHTP[001]- based sensor shows the highest response (344.17%) to 0.5 g h-FCB powder volatiles among its three other c-FCB which is much higher than Cu-HHTP[100] (135.50%). Ultimately, Cu-HHTP[001] can realize the identification of FCB with an accuracy of 97.2% in a simple and real-time manner.\u0000 \u0000 \u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"43 4","pages":"371-377"},"PeriodicalIF":5.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143115258","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}

These multisite-reactive scaffolds have aroused a long-standing interest throughout the scientific community more particularly as powerful electrophilic partners and more recently as nucleophilic partners in some specific transformations.

However, the catalytic mechanisms related to the active center and coordination environment remain unclear. In this study, we systematically investigated the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) catalytic activities of NiN4, NiN3, NiN3H2, NiN4X, NiN3X, and NiN3H2X (X denotes axial ligand) through density functional theory (DFT) calculations. This study unveils two distinct reaction pathways for ORR and OER, involving proton-electron pairs adsorbed from both the solution and the catalyst surface. The overpotential is the key parameter to evaluate the catalytic performance when proton-electron pairs are adsorbed from the solution. NiN3 and NiN3H2 show promise as pH-universal bifunctional electrocatalysts for both ORR and OER. On the other hand, when proton-electron pairs are adsorbed from the catalyst surface, the reaction energy barrier becomes the crucial metric for assessing catalytic activity. Our investigation reveals that NiN3H2 consistently exhibits optimal ORR activity across a wide pH range, regardless of the source of proton-electron pair (solvent or catalyst surface).\u0000 \u0000 \u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"43 3","pages":"297-307"},"PeriodicalIF":5.5,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143113118","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}

One of the drawbacks of the LbL-processed active layer is the large difference in the crystallinity of the donor and acceptor, which will lead to imbalance charge transfer and result in unfavorable charge recombination. Herein, we combined a novel volatile additive 3,5-dichloro-2,4,6- trifluorobenzotrifluoride (DTBF) with the LbL method to realize high-efficiency OSCs. DTBF interacts with the non-fullerene acceptor BTP-4F by non-covalent bonding, which enhances the crystallinity and compact stacking of BTP-4F. DTBF doped OSC has balanced and efficient electron transport properties, longer carrier lifetime, higher exciton dissociation and charge collection efficiencies, lower energetic disorder than the control OSC without any additives. Benefiting from the optimization of charge dynamics and micro-morphology by DTBF, the binary LbL-processed OSC achieved synergistic improvements in open-circuit voltage, short-circuit current density and fill factor. As a result, a champion power conversion efficiency (PCE) of 19% is realized for DTBF-optimized OSC, which is superior to the control OSC (17.55%). This work demonstrates a promising approach to modulate active layer morphology and fabricate high performance OSCs.\u0000 \u0000 \u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"42 24","pages":"3581-3587"},"PeriodicalIF":5.5,"publicationDate":"2024-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641357","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}
