Redox‐Switchable Optical and Magnetic Properties in a Self‐Assembled Hexanuclear Ni(II) Double‐Decker Complex

Chemistry – A European Journal, EarlyView.
A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

Multi‐Color Flexible Electrochromic Device for Smart Anti‐Counterfeiting

Angewandte Chemie, Volume 138, Issue 22, 25 May 2026.
A versatile information encryption‐decryption platform using Zn anode‐based electrochromic devices enables multicolor, on‐demand, and multiple encryption modes, breaking through the limitations of conventional static displays that rely on static, pre‐designed patterns. ABSTRACT Information security is critically important.

Facile Preparation of High-Performance Polythiophene Derivative and Effect of Torsion Angle Between Thiophene Rings on Electrochromic Color Change

Molecules
The electrochromic phenomenon of conducting polymer is mainly dominated by the π-π* band transition. The π conjugation is influenced by the coplanarity between polymer units, deviations from which can lead to an increased ionization potential and band ...

Green Electrochromic Film Formation via Phenylcarbazole Polymerization in Ionic Liquids

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
The scheme depicts the three‐step electropolymerization of two electrochromic polycarbazole derivatives, 4‐(9H‐carbazol‐9‐yl)phenol and 4‐(3‐methoxy‐9H‐carbazol‐9‐yl)phenol, performed at constant potential using the green ionic liquid BMIM TFSI. This medium enables controlled polymer growth and enhances electrochromic performance, yielding robust and ...

First Structural Determination of an Isolable and Planar Tropyl Radical

ChemistryEurope, Volume 4, Issue 8, August 2026.
Isolation of a persistent bianthryl‐substituted dibenzotropyl radical enabled the first crystallographic verification of a planar hydrocarbon‐based tropyl radical. Spectroelectrochemical studies revealed reversible redox interconversion between the cationic and radical states while retaining the planar seven‐membered framework. Planar hydrocarbon‐based
