aAbsorption maximum in CHCl3 solution. bAbsorption maximum on TiO2 was obtained through measuring the dyes adsorbed on 6 μm TiO2 nanoparticle films. cValues in CHCl3 solutions (on TiO2 film). dEoxonset was measured in CH2Cl2 with 0.1 M TBAPF6 as the electrolyte. eE0,0 was estimated from the onset point of the absorption spectra. fEox was estimated by subtracting E0,0 from the Eoxonset. |
