a The reported consecutive photoinduced electron transfer (conPET) process for the photoreduction of aryl halides. PC photocatalyst, ED electron donor, Ar-X aryl halide. 1[PC]*, the excited singlet state of PC; PC•–, the radical anion of PC; 2[PC•–]*, the excited doublet state of PC•–; ED•+, the radical cation of ED; Ar-X, aryl halide; Ar-X•–, the radical anion of Ar-X. hυ, light irradiation. b Long wavelength light-driven TS-conPET process for the photoreduction of aryl halides. PS photosensitizer, ISC intersystem crossing, TS triplet sensitization. 3[PS]*, the excited triplet state of PS. c Molecular structures of the photocatalyst PDI and the photosensitizers PdTPBP, BDP, and PtTNP.
