Fig. 7.

Absorption spectral change of Dronpa on irradiation. (a) Time evolution of the absorption spectrum of Dronpa (pH 5.0) on irradiation with a 488-nm laser (P = 10 mW/cm2). (b and c) Time evolution of the concentration of the deprotonated (b) and the photoswitched protonated (c) form on irradiation with a 488-nm laser. The solid lines show the fitting with a first-order kinetic model. (d) Time evolution of the absorption spectrum of the photoswitched Dronpa (488-nm irradiation) on irradiation with a 405-nm laser (P = 1.0 mW/cm2). (e and f) Time evolution of the concentration of the deprotonated (e) and the photoswitched protonated (f) form on irradiation with a 405-nm laser. The solid lines show the fitting with a first-order kinetic model.



Supporting Figure 8

Fig. 8.

Steady-state absorption (blue line), fluorescence (green line), and excitation spectra (black line) of photoswitched (488-nm irradiation) Dronpa at pH 7.4. The fluorescence spectrum was measured with 488-nm excitation. The excitation spectrum was measured with 540-nm detection.
