a Kinetic profile of the photocatalytic C–P coupling (0.2 mmol scale with 10 mg of bpyNi-PHI) over five catalytic cycles. b Catalyst recycling (for five catalytic cycles) of the C–N, C–O, and C–S coupling. c XRD patterns. d XPS survey spectra. e TEM images of recovered bpyNi-PHI catalyst after photocatalytic C–P coupling reaction. f 1H-NMR spectra (DMSO-d6, 400 MHz) of recovered bpyNi-PHI after treatment with 1.5 M HCl in a mixed H2O:MeOH (1:1, v-v) solvent. g Amount of nickel and ligand in recovered bpyNi-PHI determined by ICP-OES and 1H-NMR analysis.
