Table 1

Experimental data for electrochemical and spectral properties of the dyes.

Dye	𝐸D/D+[V] vs. NHE	𝐸red[V] vs. NHE	𝐸(o-o)^(b) [eV]	𝐸D^∗/D+^(c) [V]	𝜆max[nm]	Extinction coefficient [M^−1 cm^−1]
E322	0.74^(a)	−0.93^(a)	1.55	−0.81	469	4.2×10^4
N719	1.13^(d)	−1.16^(d)	1.88	−0.75	518	1.3×10^4

^(a) oxidation potential and reduction potential were measured from differential pulse voltammetry in 1 mM E322 and 0.1 M TBAPF₆ in THF, ^(b)𝐸_o-o energy was estimated from the wavelength at the tail of the absorption in longer wavelength, ^(c)𝐸_D^∗_/D+ was estimated from oxidation potential and 𝐸_o-o energy, ^(d) values were obtained by referring the value 𝐸_ox=0.5 V vs. Fc and 𝐸_1/2=−1.79 V vs. Fc from [7] and indicated vs. NHE by using the redox potential of ferrocene (0.63 V vs. NHE).
