aAbsorption and emission spectra were measured in ethanol solution. |
bA silver wire was used as a pseudoreference electrode and was calibrated with a ferrocene/ferrocenium (Fc/Fc+) redox couple. The electrochemical experiments were measured in CH3CN with 0.1 M (-C4H9)4NPF6 with a scan rate of 100 mVs−1.
c was determined from intersection of absorption and emission spectra in ethanol.
dThe energy levels of the HOMO and LUMO were determined using the following equations: (eV) = − + 4.8 eV and (eV) = − .
