The role of catalysis in controlling chemical reactions is crucial. As an important external stimulus regulatory tool, electric field (EF) catalysis enables further possibilities for chemical reaction regulation. To date, the regulation mechanism of electric fields and electrons on chemical reactions has been modeled. The electric field at the single-molecule electronic scale provides a powerful theoretical weapon to explore the dynamics of individual chemical reactions. The combination of electric fields and single-molecule electronic techniques not only uncovers new principles but also results in the regulation of chemical reactions at the single-molecule scale. This perspective focuses on the recent electric field-catalyzed, single-molecule chemical reactions and assembly, and highlights promising outlooks for future work in single-molecule catalysis.

Carbon aerogels and xerogels, with their 3D porous architectures, ultralow density, high surface area, and excellent conductivity, have emerged as multifunctional materials for energy and environmental applications. This review highlights recent advances in the synthesis of these materials polymerisation, drying, and carbonisation, as well as the role of novel precursors such as graphene, carbon nanotubes, and biomass. Emphasis is also placed on doped and metal-decorated carbon gels as efficient electrocatalysts for oxygen reduction reactions, enabling four- and two-electron pathways for energy conversion and the production of green HO, respectively.

A visible-light-catalyzed three-component cyclization reaction of 2-vinylarylamines with CFSONa and arylaldehydes is developed to build a series of 3-(2,2,2-trifluoroethyl)-3-indoles. This protocol features mild reaction conditions using an 18 W blue LED as the light source at room temperature. The desired 3-indole products can be successfully transformed into valuable tetrahydroindole scaffolds through either reduction or cross-coupling reactions.

Surface photocatalysis holds significant promise for converting solar energy into chemical fuels and addressing environmental challenges. While calculations provide critical insights into the thermodynamic and kinetic aspects of catalytic reactions, applying these methods to surface photocatalysis remains challenging. In this work, we discuss the key challenges that need to be addressed when using calculations to understand surface photocatalytic processes, the reasons behind these challenges, and the potential directions and opportunities for overcoming them in the future.

Hybrid systems (HSs) of quantum dots (QDs) and molecular photoswitches exhibit luminescence switching of QDs based on energy transfer and have garnered attention for their potential applications in sensors and optical memories. In HSs, the chemical composition, such as the number of attached ligands, is inherently distributed, posing challenges for extracting the energy transfer process from the QDs to a single acceptor molecule. The stochastic model, assuming a Poisson distribution for the number of acceptors, proves to be an effective approach for extracting the process.

Presented herein is a protocol for the iron-catalyzed [4 + 1] cycloadditions of -Boc-imines with β-ketosulfoxonum ylides through a succession of nucleophilic additions and intramolecular annulation, giving access to functionalized oxazolidine-2-ones in generally good yields. In contrast to the renown Corey-Chaykovsky reaction via N attack to furnish aziridines, this method afforded oxazolidine-2-ones via an O-nucleophilic attack. Features of this strategy include readily accessible starting materials, sustainable catalyst, post-functionalizations of complex molecules, scalability, and exceptional control over diastereoselectivity.
