Herein, we have developed a sustainable linear paired electrolysis strategy for the redox-neutral benzylation of N-heteroarenes with benzyl halides using solid ion resin as the recyclable electrolyte. This method sufficiently utilizes both cathodic and anodic reactions to produce a variety of benzylated N-heteroarenes, features high atom- and step-economy, excellent energy efficiency, operational simplicity, good functional group tolerance, mild conditions and no requirement of sacrifice reagent and base additive. Importantly, the inexpensive and commercially available solid ion resin electrolyte was validated in both gram-scale synthesis and electrolyte cycling experiment. We hope this strategy not only provides a sustainable synthetic strategy for benzylated compounds but also develops the further utilization of ion resin in electrosynthesis as well as linear paired electrolysis.

Digital microfluidics (DMF) shows great promise in addressing the need for miniaturization and automation in immunoassay detection. Despite recent advances, an automatically operated, multiplexed heterogeneous immunoassay platform powered by DMF remains underdeveloped. Here we present a DMF platform for automated and multiplexed heterogeneous immunoassay detection by coupling spatial barcoding with automatic and uniform droplet dispensing. FluoroPel was selected as a robust hydrophobic reagent for coating the DMF top plate, and it also served as the substrate for the immuno-reaction. Its mechanical robustness was further enhanced with a Cytop CTL-809A adhesive layer under the top hydrophobic layer. Hourglass-shaped electrode patterns ensured consistent and uniform distribution of immunoassay reagents, with volume variation down to 1.0 %. The analysis duration was significantly reduced from 75 min to 20 min after a heating module was integrated to elevate the immuno-reaction temperature to 37 °C. Utilizing a compact instrument featuring a multi-droplet manipulation protocol, we successfully implemented fully operated, multi-sample, multiplexed immunoassays using recombinant proteins on cell culture supernatants on the DMF platform. This innovative platform significantly enhances the efficiency, reliability, and degree of automation of DMF-actuated multiplexed heterogeneous immunoassays, potentially providing a viable solution for field deployment and multi-sample parallel diagnosis.

The asymmetric catalytic synthesis of planar chiral ferrocene derivatives has received dramatic attention in recent years. Transition metal-catalyzed asymmetric cross-coupling reactions and CH functionalization reactions have played significant roles in the stereoselective construction of planar chiral ferrocene derivatives. Transition metals such as copper, palladium, rhodium, iridium, gold, and platinum have been adopted as the effective catalysts in combination with various chiral ligands to achieve satisfactory yields and stereoselectivity. Organic catalysts have also shown great potential in the synthesis of planar chiral ferrocenes. Chiral amines and N-heterocyclic carbenes (NHCs) have been the key catalysts for facile access to multi-functional ferrocene derivatives. Some of the planar chiral ferrocene molecules obtained from the above methods have demonstrated promising applications in the development of novel ligands for asymmetric synthesis and pesticides for plant protection. This review provides an overview on the key progresses in the catalytic synthesis of planar chiral ferrocene derivatives using transition metal catalysts and organic catalysts. The merits, challenges and potential directions in the future development within this highly active research field are also discussed at the end of this review.

In the field of organic solar cells (OSCs), side-chain engineering is a key strategy for developing high-performance non-fullerene small molecule acceptors (SMAs), which could adjust the material solubility and modulate the intermolecular stacking properties, profoundly impacting the film morphology and thus acting on the final power conversion efficiency (PCE) of the materials. In this study, two asymmetric acceptor molecules, Qx-PhBr-BO and Qx-PhBr-X, were synthesized by migrating the branching site of the outer side chain from the β-site to the γ-site. The branching site located at the γ-site could reduce the steric-hindrance effect and enhance the molecular aggregation behavior, giving rise to redshifted absorption and tight π-π stacking. Morphology analysis shows that the Qx-PhBr-X-based devices have smoother surfaces and a phase-separated structure, which is more favorable for charge transport and extraction. The Qx-PhBr-X-based devices exhibit balanced hole-electron mobility, efficient exciton dissociation, and low charge recombination. As a result, Qx-PhBr-X with γ-site branching exhibits superior photovoltaic performance with a PCE of 17.16 %, which is significantly higher than that of Qx-PhBr-BO at 16.28 %. These results highlight the importance of side-chain modifications for optimizing OSC efficiency and provide an important reference for precise tuning of side-chain structures in future molecular design.

Thermo-photocatalytic CO2 conversion to C2 products exhibits high research value and industrial potential. Enhancing the catalyst’s adsorption activation for CO2 and H2O, along with multistep proton-coupled electron transfer (PCET) and C-C coupling, is crucial for achieving thermo-photocatalytic CO2 reduction conversion to C2 products with H2O as a proton source in a continuous process. In this paper, we explore a novel approach utilizing biochar to obtain catalysts with more defects and combine reducing biochar with MOF Materials (ZIF-67) to get a composite (ZIF-67/PC) with substantial CO2 and H2O adsorption activation capabilities and electron density gradients. Compared to PC and ZIF-67, the ZIF-67/PC exhibited excellent catalytic performance, particularly in obtaining a certain amount of C2 products (yield 5.59 µmol g-1 h-1, selectivity 55.96%). We also investigated the structure-function relationship of the catalyst and the contributions of thermal and light effects to the catalytic reaction, aiming to guide the establishment of efficient, high-throughput catalytic CO2 conversion technologies.

α-Chiral amides are common in pharmaceuticals, agrochemicals, natural products, and peptides, prompting the need for new synthetic methods. Here, we introduce a nickel-catalyzed asymmetric reductive amidation method to synthesize α-chiral amides from benzyl ammonium salts and isocyanates. The key to success is using a chiral 2,2′-bipyridine ligand (-)-Ph-SBpy, enabling high yield (up to 95 %) and enantiomeric ratio (up to 98:2 er) under mild conditions. Addition of phenol prevents isocyanate polymerization by reversibly forming a carbamate intermediate, enhancing selectivity and efficiency. The synthetic utility is showcased through transformations of the enantioenriched amides, and the mechanism and enantioselectivity are supported by experimental and computational studies.

The first example of heterogeneous direct benzylation of N-heterocycles (quinoxalin-2(1H)-ones and quinoxalines) with benzaldehydes has been accomplished via the sequence of a NaDT-photocatalyzed HAT, a single electron transfer reduction and a proton transfer, a spin-center shift and a back-HAT. Utilizing this strategy, a diverse array of benzylated N-heterocycles (29 examples) can be produced with high yields. Importantly, the DT-photocatalyzed direct benzylation with benzaldehydes would be a useful complement to the more extensively studied DT-photocatalyzed acylation and hydroxyalkylation, expanding the scope of DT photocatalysis.

The three-dimensional (3D) Pd-based nanoflower structures, assembled from two-dimensional (2D) nanosheets, are characterized by their stable and ordered configurations. These structures have been extensively designed as anode materials for fuel cells. However, the exploration of trimetallic nanoflowers with porous architectures remains limited. In this study, we present a straightforward one-step solvothermal method for the synthesis of trimetallic PdCuNi porous nanoflowers (PNFs). Leveraging several unique advantages, such as an open superstructure, high porosity, and enhanced electronic interactions among the trimetals, the resulting PdCuNi PNFs demonstrate significantly improved electrochemical performance, with mass activities reaching 5.94 and 10.14 A/mg for the ethanol oxidation reaction (EOR) and the ethylene glycol oxidation reaction (EGOR), respectively. Furthermore, the PdCuNi PNFs exhibit optimized d-band centers and the most negative onset oxidation potential, indicating enhanced antitoxicity and stability. This study not only provides a novel perspective on the synthesis of 3D porous nanomaterials but also highlights the potential application value of trimetallic nanoalloys in catalysis.
