Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Modulating Perovskite Crystallization via Multisite Bonding for Enhanced Solar Cell Performance
This study proposes an innovative multisite bonding strategy to regulate crystallization. By employing bidentate ligands N,N‐diethyl‐1,2‐ethanediamine dihydrochloride (DED) that coordinate with uncoordinated Pb2+ and I− vacancies, while simultaneously forming hydrogen bonds with FA+ ions, this synergistic interaction prolongs the perovskite ...

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...

Organotrifluoroborate‐Driven Phase Stabilization and Defect Suppression for Wide‐Bandgap Perovskites
A multifunctional additive, trifluoro(pyrrolidin‐1‐ium‐1‐ylmethyl) borate (PyMe‐BF3), leverages B‐F coordination and N‐H hydrogen bonding to passivate undercoordinated Pb2+, fill halide vacancies, and suppress phase segregation. Its preferential enrichment at the buried interface targets the defect‐rich region, enabling simultaneous wide‐bandgap ...

Molten Salt Electrolyte for Enhanced Low‐Temperature Sodium Liquid Metal Batteries
This study introduces the application of a low‐temperature, high‐conductivity, solvent‐free Na/KFSI molten salt electrolyte in sodium liquid metal batteries. Additionally, this electrolyte facilitates the formation of a stable and NaF‐rich cathode electrolyte interphase (CEI) on the alloy cathode, enabling stable cycling at an unprecedentedly low ...
