Fig. 2: Photochemical properties of DASA-CF3-PI in chloroform and toluene.

a Bleaching front progression through 0.25 mM DASA-CF3-PI in chloroform stabilized with 0.75% ethanol (top) and toluene (bottom) irradiated with 25 mW cm−2 light. b Reversible switching kinetics of DASA-CF3-PI in chloroform and toluene at 10 μM. c Bleaching front length versus time for 0.125 mM DASA in chloroform, where the slope provides a measure of the front velocity. d Absorbance of DASA-CF3-PI in toluene and chloroform at 14 μM.
