Absorption spectra and cyclic voltammograms recorded in CH₂Cl₂.

0-0 transition energy estimated from the onset of the absorption spectra.

Reduction potential in V vs. Fc⁺/Fc.

Estimated LUMO level in V vs. NHE, obtained from the reduction potential considering E⁰(Fc+/Fc) = + 0.53 vs. NHE.[15,25]

Estimated LUMO energy in eV, considering E⁰_(Fc+/Fc) = – 5.1 eV.[26]

Estimated HOMO level in V vs. NHE, obtained from E_LUMO+E_0-0.

Estimated HOMO energy in eV, obtained from E_LUMO–E_0-0.
