High Capacity and Stable Lithium‐Ion Cathodes Based on a Mellitic Trianhydride–Phenylenediamine Porous Polyimide

Batteries &Supercaps, Volume 9, Issue 2, February 2026.
A redox‐active polyimide porous organic polymer, PI(MTA–PDA), operates as a lithium‐ion battery cathode through a three‐electron imide carbonyl redox process. Its carbonyl‐rich, π‐conjugated and microporous framework enables reversible capacities near 230 mAh g−1, about 95% capacity retention over 600 cycles, and good rate capability up to 4 C. Organic

High Potential Isoindoline‐Based Nitroxides Posolytes for Aqueous Organic Redox Flow Batteries

ChemSusChem, Volume 19, Issue 3, February 2026.
A convenient metal‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of isoindoline‐based nitroxides as new posolytes for aqueous organic redox flow batteries. The cationic PPO exhibits a 220 mV higher oxidation potential than 4‐TMA‐TEMPO, 3 M solubility in 1 M NaCl, and a cell voltage of 1.56 V.

Fine‐Tuned Magnetic and Electrochemical Properties of a Series of Fe(II) Complexes with Asymmetric Jäger‐Type (N2O2)2− Ligands

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 1, January 6, 2026.
Asymmetrically substituted Jäger‐type ligands and their Fe(II) complexes show additive optical and redox trends. Ketone donors promote spin‐crossover while ester donors stabilize the high‐spin state, yet bulk materials display unexpected transitions governed by molecular symmetry and packing. A series of seven new asymmetrically substituted Jäger‐type (

New Approach to Electrode Kinetic Measurements in Square-Wave Voltammetry: Amplitude-Based Quasireversible Maximum

Analytical Chemistry, 2013
The influence of the potential pulse height of square-wave voltammetry (SWV) (i.e., the SW amplitude) is studied for a variety of quasireversible electrode mechanisms, including a simple solution-phase electrode reaction at a planar or spherical electrode, a solution phase electrode reaction coupled with a reversible follow-up chemical reaction, and a ...
