Their specific reactivity found widespread applications in the field of bioconjugation and allowed for the development of highly selective functionalizations based on simple additions and cycloadditions with the possible control of central and C–N axial chirality. 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. The persistent interest in these easily accessible synthetic platforms over the last decade has enabled the development of new enantioselective transformations and the major advancements in this field are presented in this review.</p>\u0000 \u0000 <p>\u0000 </p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Key Scientists</h3>\u0000 \u0000 <p>\u0000 \u0000 </p>\u0000 </section>\u0000 </div>","PeriodicalId":151,"journal":{"name":"Chinese Journal of Chemistry","volume":"42 24","pages":"3605-3622"},"PeriodicalIF":5.5,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cjoc.202400787","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","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 (<i>PCE</i>) of 19% is realized for DTBF-optimized OSC, which is superior to the control OSC (17.55%).

However, medium-bandgap PSMAs are often overlooked, while they as the third component can be expected to boost power conversion efficiencies (PCEs) of all-PSCs, mainly due to their up-shifted lowest unoccupied molecular orbital (LUMO) energy level, complimentary absorption, and diverse intermolecular interaction compared to the NIR-absorbing host acceptor. Herein, an IDIC-series medium-bandgap PSMA (P-ITTC) is developed and introduced as the third component into D18/PY-IT host, which can not only form complementary absorption and cascade energy level, but also finely optimize active layer morphology. Therefore, compared to the D18/PY-IT based parental all-PSCs, the ternary all-PSCs based on D18/PY-IT:P-ITTC obtain an increased exciton dissociation, charge transport, carrier lifetime, as well as suppressed charge recombination and energy loss. As a result, the ternary all-PSCs achieve a high PCE of 17.64% with a photovoltage of 0.96 V, both of which are among the top values in layer-by-layer typed all-PSCs.

Enzymatic catalysis has become a powerful tool for asymmetric synthesis, though it is typically limited to a relatively narrow range of reaction types. By integrating the advantages of enzymatic catalysis with photocatalysis, photoenzymatic catalysis not only expands the catalytic capabilities of enzymes but also provides an effective strategy for the stereo-control of photochemical reactions, thereby emerging as a significant research field. Herein, we focus on new-to-nature photoenzymatic catalysis by repurposing naturally occurring enzymes with visible light.
