A Bifunctional Spin Label for Ligand Recognition on Surfaces. [PDF]

open access: yes, 2017
In situ monitoring of biomolecular recognition, especially at surfaces, still presents a significant technical challenge. Electron paramagnetic resonance (EPR) of biomolecules spin-labeled with nitroxides can offer uniquely sensitive and selective ...

Interplay between lattice, orbital, and magnetic degrees of freedom in the chain-polymer Cu(II) breathing crystals [PDF]

open access: yes, 2013
The chain-polymer Cu(II) breathing crystals C21H19CuF12N4O6 were studied using the x-ray diffraction and ab initio band structure calculations. We show that the crystal structure modification at T=146 K, associated with the spin crossover transition ...

Unraveling Charging and Discharging Processes in Organic Radical‐Based Electrodes: A Hierarchical Molecular and Quantum Mechanical Approach

open access: yesChemSusChem, Volume 19, Issue 6, 27 March 2026.
Charge transfer processes are investigated in p‐type organic electrode materials utilizing stable organic radicals incorporated in a conjugated backbone. Molecular dynamics simulations and time‐dependent density functional theory calculations allow us to evaluate charge transfer states as well as the underlying structure–property relationships. Organic
