Spin Crossover-Mediated Low-Energy Charge Transfer Excited States in a Heterogeneous Cobalt Photocatalyst.
In molecular complexes, ligand-to-metal charge transfer (LMCT) excited states enable efficient photoinduced charge separation and strong redox reactivity, but their operation is typically limited to short ultraviolet excitation. Extending LMCT absorption into the visible region utilizing strongly donating ligands often...
