    • We estimated the relative quantum yields of trans-cis photoisomerization for 1-3 in two ways. First, while determining the rate of thermal cis-trans isomerization, we estimated the magnitude of ΔA on photolysis using identical conditions for each dye (concentration, light intensity, geometry). 2 showed a much smaller change in absorbance than 1 or 3. Second, in nanosecond flash photolysis studies to be reported elsewhere, we found no intermediate absorption with a lifetime longer than 2 ns for 1, 2, or 3; we found only an immediate decrease in absorbance, at the long wavelength absorption peak, which persisted for several seconds. This change was largest for 3, within the noise for 2, and its magnitude is attributed to the extent of photoisomerization.
