From: Photocathodes beyond NiO: charge transfer dynamics in a π-conjugated polymer functionalized with Ru photosensitizers

Figure 1

Schematic representation of the molecular structures of π-conjugated PPV with RuII chromophores in the side chains, i.e. Ru1 and Ru2. Transient absorption spectroscopy is employed to unravel light-driven (1) hole injection (2) and charge recombination (3) dynamics in PPV-Ru. The red and blue shadings schematically indicate photogenerated holes residing on the PPV and the radical anion after hole injection from the photosensitizer to the PPV, respectively.
