Der Nicht‐Adiabatische Charakter von Substituenteneffekten in Azobenzol

open access: yesAngewandte Chemie, Volume 138, Issue 14, 27 March 2026.
Vereinheitlichung Nicht‐Adiabatischen Schaltens: die thermische Z→E Isomerisierung von para‐substitutierten Azobenzolen verläuft über einen einzelnen Reaktionsweg mit nicht‐adiabatischem Charakter. Anstatt eines mechanistischen Wechsels spiegelt der bekannte V‐förmige Hammett Graph ein Artefakt des σp Parameters, zeigt so die Grenzen von DFT auf und ...

The Nonadiabatic Nature of the Substituent Effects in Azobenzene

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 14, 27 March 2026.
Unified nonadiabatic switching: thermal Z→E isomerization of para‐substituted azobenzenes proceeds through a single nonadiabatic rotational pathway. The iconic bell‐shaped Hammett plot is a σp artifact, not a reflection of a mechanistic change, exposing the limits of single‐reference density functional theory (DFT) and establishing activation entropy ...

Transverse Square Toroidal Vortices with Giant Ferrotoroidic Coupling in Dy‐Bridged Single‐Molecule Toroics

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 9, 20 March 2026.
Single‐molecular toroics (SMTs) offer protected magnetic states for next‐generation quantum technologies. Ab initio and model analyses of Cu2Dy7 and Cu4Dy12 reveal unconventional excited states featuring delocalised toroidal moments that couple into strong ferro‐ and antiferrotoroidic configurations, providing unprecedented magnetic coupling within ...
