Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores
Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.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 ...
