Abstract ：
Single-molecule junctions are building blocks for constructing molecular devices. However, intermolecular interactions like winding bring additional interference among the surrounding molecules, which inhibits the intrinsic coherent transport through single-molecule junctions. Here, we employed a nanocavity (dimethoxypillar [5] arene, DMP[5]), which is analogous to electric cables, to confine the conformation of flexible chains (1,8-diaminooctane, DAO) via host-guest interaction. Single-molecule conductance measurements indicate that the conductance of DAO encapsulated with DMP[5] is as high as that of pure DAO, as reproduced by theoretical simulations. Intriguingly, the molecular lengths of the DAO encapsulated with DMP[5] increase from 1.13 nm to 1.46 nm compared with the pure DAO, indicating that DMP[5] keeps DAO upright-standing via the confinement effect. This work provides a new strategy to decouple the intermolecular interaction by employing an insulating sheath, enabling the high-density integration of single-molecule devices.

Abstract ：
Hydrogen peroxide (H2O2) is a versatile compound with widespread applications in various industries. In addition, it has attracted interest as a potential energy carrier due to its high energy density and ability to release oxygen upon decomposition. The development of photocatalytic technology has enabled sustainable production of H2O2. Various structural materials, including organic molecules, polymers, and metal coordination compounds, have been synthesized for investigating photocatalytic H2O2 production. Rare earth materials, in particular, are of interest due to their adjustable porosity and controllable metal active sites, making them valuable for research in this field. These materials have excellent photoelectric properties, making them promise for the photocatalytic synthesis of H2O2. Despite limited reports on systematic reviews of photocatalytic H2O2 production using rare earth materials, this study introduces the principles and advancements in this area. It reviews different methods of photocatalytic synthesis of H2O2, focusing on rare earth elements. Through comprehensive analysis and systematic studies in the existing literature, a deeper understanding of enhanced photocatalytic performance has been achieved. This research not only contributes to advancing fundamental knowledge but also provides a solid foundation for practical applications. (c) 2024 Chinese Society of Rare Earths.
