^aMeasured in CH₃OH under air at room temperature.
^bElectrochemical measurements were performed in deoxygenated MeCN with 0.1 M n-Bu₄NPF₆ as the supporting electrolyte; the potentials were measured vs. Ag/AgCl couple and converted to the normal hydrogen electrode (NHE).
^cE_0-0 values were estimated from the intersection of the normalized absorption and the emission spectra in CH₂Cl₂ at room temperature.
^dE(PS*/PS⁻) = E_red + E_0-0; E(PS⁺/PS*) = E_ox − E_0-0.
^eMeasured in nitrogen-saturated CH₂Cl₂ at room temperature.
