Electrochemical Performance Screening of Cu‐Based Multimetal Electrocatalysts for CO2 Reduction

ChemElectroChem, Volume 13, Issue 17, 1 September 2026.
Electrocatalytic CO2 reduction reaction performance for lanthanoids and similar rare‐earth elements such as Gd, Sc, Tb, Nd, Sm, and Y as components in CuAgAl catalysts was explored with respect to product selectivity. Gd‐containing catalysts showed high Faradaic efficiency for C2+ products > 60% at a current density of −400 mA cm−2.

4CzIPN Photosensitizes the Cobaloxime‐Catalyzed Light‐Driven Hydrogen Evolution Reaction

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
2,4,5,6‐Tetra(9H‐carbazol‐9‐yl)isophthalonitrile (4CzIPN) as photosensitizer enables turnover numbers above 5000 in the cobaloxime‐catalyzed hydrogen evolution reaction via efficient quenching of its excited singlet state by ascorbate. Thermally activated delayed fluorescence (TADF) compounds have found great application as photocatalysts in recent ...

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 ...

Aromaticity‐Engineered Open‐Shell Radical Anions for Air‐Stable Doublet Emission in N‐Annulated Perylene Diimide

Advanced Science, Volume 13, Issue 47, 24 August 2026.
Open‐shell type radical anions with stable doublet emission have been synthesized that feature aromaticity engineering, through‐space charge‐transfer (TSCT), and electro(fluoro)chromism. ABSTRACT We report the doublet emissive open‐shell radical anions, where the N‐annulated perylene diimide (PDIN–H) is functionalized with aromatic rings.

Furan, Selenophene, and Thiophene‐Bridged Triphenylamine Polymer Films: A Systematic Chalcogen Study of Bifunctional Electrochromic Supercapacitor Electrodes

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Synthesis and electropolymerization of TPA‐based conjugated polymers (P1‐P3) incorporating furan, selenophene, and thiophene π‐bridges were performed. The fabricated asymmetric electrochromic supercapacitor devices (P1‐P3//PEDOT) demonstrated excellent dual stability: optical contrast values decreased by only 3%–5% after 5000 GCD cycles, while P3 ...
