Fig. 5. Femtosecond transient absorption measurements.

TA details of CYANO-CON and BD-CON pumped at 400 nm. a Time slices of the TA spectra of CYANO-CON in water. b TA kinetics of CYANO-CON probed at 510 nm (GSB) and 650 nm (trapped hole). Comparison of the kinetics for CYANO-CON and BD-CON c probed at 650 nm (0–80 ps for trapped hole) and d probed at 650 nm (10–8000 ps for long-lived free electron) in the presence of 0.1 M ascorbic acid.
