Journal of the American Chemical Society, Год журнала: 2025, Номер unknown

Опубликована: Фев. 10, 2025

Covalent organic multicycles (COMs) have been designed and synthesized via the covalent assembly of rigid three-arm Y-shaped U-shaped building blocks. These COMs a precise tricyclic structure exhibit remarkable solubility in range common solvents. Featuring well-defined cavities with electron-rich structures, these displayed good adsorption capabilities for iodine both its vapor liquid states. Moreover, solution processability allows facile fabrication as uniform films on different substrates spin coating methods.

Atomic Sn–incorporated subnanopore-rich hard carbon host for highly reversible quasi-metallic Li storage

Science Advances, Год журнала: 2025, Номер 11(8)

Опубликована: Фев. 21, 2025

The practical application of Li metal anodes has been hindered by severely irreversible side reactions for low Coulombic efficiency, uncontrollable growth dendrites, and large volume change. Herein, we report subnanopore-rich carbon spheres encapsulated with Sn single atoms (Sn/CS@SC) as a host to address these challenges. Owing the high affinity atoms, Sn/CS@SC can promote storage quasi-metallic within inner void space other than direct plating metallic on outer surface. Moreover, subnanopores strong spatial confinement effect prevent penetration ester electrolyte reduced reactions. As expected, demonstrates efficiency 99.8% over 600 cycles. full cell using prelithiated anode LiNi0.8Co0.1Mn0.1O2 cathode shows capacity retention (~80%) 500 cycles at current density.

Abstract Controlling the self‐assembly and aggregation behavior of nanographdiyne (NanoGDY) in solution is crucial for understanding intrinsic structure‐property relationships graphdiyne. However, capturing persistent NanoGDY dimer aggregate presents a significant challenge. Herein, we have successfully synthesized novel ester‐functionalized with solubilized alkyl chains at periphery named NanoGDY‐CO investigated its different temperatures as well solvents by 1 H NMR, UV–vis, FL spectroscopy. The combination intermolecular hydrogen bonding formed ester groups π─π stacking facilitates into coplanar slip‐stacked dimer. In contrast, branched 2‐octyldodecyl substituent acts steric control agent preventing further self‐assembled This work offers new insights manipulating NanoGDYs solution.
