Normalized UV/Vis absorption and emission spectra of (a) PPV, (b) Ru1, PPV, and PPV-Ru1, and (c) Ru2, PPV, and PPV-Ru2 in CHCl3. All emission spectra were obtained upon excitation at 480 nm. Emission decay of (d) Ru1 and PPV-Ru1, and (e) Ru2 and PPV-Ru2 in CHCl3 upon excitation at 390 nm. The emission decay was measured using time-correlated single photon counting. The initial fast decay (< 1 ns) arises from the instrumental response function. (f) Cyclic voltammogram of 0.25 mM Ru1 and Ru2 in acetonitrile using 0.1 M TBABF4 as supporting electrolyte.
