    • Strictly speaking, there is still a small possibility for the molecule to jump to the dim state during the long "on" state. The dim state (cis-Cy5) occurs in solution more frequently than on the dry glass surface. The on ↔ dim transition is a statistical process that happens on average after a certain number of photocycles. More on ↔ dim transitions will be expected with increasing excitation intensity because of the thermoinduced back-isomerization from cis to trans conformations; the saturated counts at higher excitation power as shown in Figure 3b may probably be due to more on ↔ dim transitions before photobleaching. From the laser photolysis results, the RISC could only happen in the trans isomer rather than in the cis isomer since the excited wavelength used for single molecule measurements is in resonance with the ground-state absorption and triplet state absorption of trans isomer. Therefore, to determine the RISC at single molecule levels, we must choose those single molecules on the glass with the more stable "on" state.
