Long wavelength near-infrared and red light-driven consecutive photo-induced electron transfer for highly effective photoredox catalysis.

ABSTRACT: Consecutive photoinduced electron transfer (conPET) processes accumulate the energies of two photons to overcome the thermodynamic limit of traditional photoredox catalysis. However, the excitation wavelength of conPET systems mainly focused on short wavelength visible light, leading to photodamage and incompatibility with large-scale reactions. Herein, we report on conPET systems triggered by near-infrared (NIR) and red light. Specifically, a blue-absorbing conPET photocatalyst, perylene diimide (PDI) is sensitized by a palladium-based photosensitizer to triplet excited state (³PDI^*), which generates PDI radical anion (PDI^•-) over 100-fold faster than that in the conventional conPET. Accordingly, photoreduction with superior reaction rate and penetration d
