Fig. 4 — Characterization of reaction dynamics and photocatalyst recyclability. a The kinetics of the ingress and egress of substrate 1a on Zn–TCTA block crystals in an acetonitrile suspension and the time-dependent conversion plots of the photocatalytic transformation with the insert showing the enlarged ingress/egress curves. b Histograms of the time-course reactions of excess 1a (2.5 mmol, 10 equiv) in the presence of Zn–TCTA and fac-Ir(Fppy)₃ (6.25 μmol, 2.5 mol%) as photocatalysts, respectively. c Time-conversion plots of three rounds of the reaction using recycled catalyst Zn–TCTA. d A magnified TEM image of a crystalline powder of the photocatalyst Zn–TCTA after three rounds of reaction, showing the step-like cross-section of the laminated thin layers (inset, scale bar, 20 nm)
