Fig. 2: TAS measurements of CN, ^mCD/CN and ^sCD/CN.

Diffuse reflectance TAS spectra for samples with (a–c) and without (d–f) 10 mM AgNO₃. CN (a, d), ^mCD/CN (b, e) and ^sCD/CN (c, f) were dispersed in aqueous solution. The change of signal amplitude at 700 nm indicates it should be mainly assigned to the electron signal in CN and ^mCD improves the charge separation on CN due to hole transfer from CN to ^mCD. g μs-TAS decay kinetics of CN, ^mCD/CN and ^sCD/CN in water monitored at 700 nm and excited by pulsed 355 nm excitation (460 μJ/cm²) and h fitted α parameters indicated in the same color as the associated trace.
