Photoinduced ET schemes. The molecular structure of the DA molecule, RuPZn−NDI is shown, along with one-way, and U-turn ET schemes. One-way or U-turn ET events are phototriggered by excitation of the donor (D) chromophore (RuPZn) into its S3 or S1 singlet excited states, respectively. Structures of ancillary groups R1 and R2 are shown in SI Appendix, Scheme S1.
