NR, not reported.

^aProduct of extinction coefficient and quantum yield.

^bDetermined by the green-to-cyan fluorescence ratio after photoactivation divided by the green-to-cyan fluorescence ratio before photoactivation.

^cDetermined by the red-to-green fluorescence ratio after photoactivation divided by the red-to-green fluorescence ratio before photoactivation.

^dDetermined by ratio of the maximum signal divided by the residual off-state fluorescence.
