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 ...

Generation of a Ground‐State Electron Donor Utilizing Stored Light Energy
Chemistry – A European Journal, EarlyView.Chemically stored light energy enables the generation of dianion reductants (∼−2.7 V) from vicinal diols derived from diaryl ketone photodimerization. These ground‐state electron donors efficiently reduce challenging substrates at room temperature, including aryl bromides, alkyl iodides, and sulfonamides.
