    • The overlapped UV/Vis absorption spectra for (E)-1 and (Z)-1 preclude the use of UV/Vis spectroscopy for unambiguous evaluation of their molar ratio in the photostationary states. Thus, their molar ratio was determined by HPLC analysis

    • The isomerization quantum yield measurement was conducted with excitation at 313 nm, which is the same as the transa→cis isomerization quantum yield measurement for the actinometer, trans-4-(phenylamino)stilbene. See:,. This actinometer was chosen because of its better resolution in HPLC traces as compared to trans-stilbene.

    • For solubility reasons, the solvent contains 20% THF for the photoisomerization quantum yield measurement. The highest and lowest [(E)-2 ]/[(Z)-2 ] ratio in photostationary states are 98:2 (420 nm) and 25:75 (313 nm), respectively, corresponding to 73% molar reversibility
