Aromaticity‐Switchable Tetraoxa[8]circulenes as Anode Materials for Sodium‐Ion Batteries

open access: yesChemistryEurope, EarlyView.
Aromaticity‐based electrode materials have received substantial interest in recent years. Herein, a naphtho‐tetraoxa[8]circulene (N‐TOC) is introduced, its electrochemical performance is investigated, and its charge‐storage mechanism through aromaticity switching described by computational calculations.

Electrochemical Water Oxidation Mechanisms Involving Macrocyclic Copper(II) Complexes: Ligand Ring Size Effects on Catalytic Cycles

open access: yesChemPhysChem, EarlyView.
The ring size of the ligand strongly influences electronic properties, steric effects, and coordination modes of key intermediates. Both catalysts show similar energy barriers for OO bond formation, but [Cu(12‐TMC)]2+ exhibits more complex mechanisms due to ligand reorganization.
