a Comparison of the product yields of the red-light (625 nm) and blue light (455 nm) LED driven photoreduction of 4-bromoacetophenone under different irradiation time (2, 4, 8, 16 h). b The product yields of different reaction volumes including 2 mL and 20 mL under blue (455 nm) and red-light (625 nm) illumination for 4 h. c The picture of sunlight driven photoreduction of 4-bromoacetophenone with a 600 nm long-pass filter to reject the light of wavelength shorter than 600 nm to enter into the reaction setup. The corresponding photocatalyst component of PdTPBP/PDI or PDI alone are marked.
