Direct Capture of Dynamic Surface Reconstruction in a Perovskite Cathode via Operando Raman Spectroscopy

Carbon Energy, EarlyView.
Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores

Chemistry – A European Journal, EarlyView.
Redox and excited state properties of organic and precious metal CT photocatalysts are strongly entangled. In contrast, redox potentials of polypyridine chromium(III) complexes, that feature purely metal‐centered SF states, are selectively tuned by incremental substituent effects of the CF3 group, while excited state energies and lifetimes remain ...

Arene Incorporation and Ring Expansion in the Thermal Decomposition of a Divanadium(III) Complex With Four Bridging Methyl Groups

Chemistry – A European Journal, EarlyView.
Thermolysis of [{VCp*(µ‐CH3)2}2] (Cp* = η5‐C5Me5) in hexane leads to a tetranuclear cube‐type methylidene complex [{VCp*(µ3‐CH2)}4], while in benzenic solvents C6H5R produces the formal insertion of a CH fragment into the six‐membered aromatic ring of a solvent molecule to give trovacene derivatives with η7‐cycloheptatrienyl ligands [VCp*(η7‐C7H6R ...

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

Chemistry – A European Journal, EarlyView.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...
