Figure 3

Fs-transient absorption spectra of (a) PPV, (b) Ru1 and (c) PPV-Ru1 at different delay times measured in CHCl3 solution with an excitation wavelength of 480 nm. The shaded areas at 360, 500 and 670 nm indicate the different spectral signatures among PPV, Ru1, and PPV-Ru1. The insets in figures (a) and (c) show the zero-crossing (ΔOD = 0) at 0.5 ps for PPV and PPV-Ru1, respectively. TBABF4 as supporting electrolyte.
