a Photoluminescent emission spectra (λex = 400 nm) of TpPa-SCOF-An, TpPa-SCOF, TpPa-COF-An, and TpPa-COF, respectively. b Normalized transient kinetic decay monitored at 580 nm after pulsed 532 nm excitation for TpPa-SCOF-An and (c) TpPa-COF-An, in the presence and absence of the loading of Pt cocatalyst. Bleach signals were normalized to 1 for clear comparison. The overlaid curves in orange and green are kinetic fits to the multi-exponential kinetic model. d Transient photocurrent responses and (e) Nyquist plots from electrochemical impedance spectroscopy. Source data are provided as a Source Data file.
