Figure 1

UV–vis spectral changes of (A) (E)-1 (B) and (Z)-1 (2.5 × 10–5 M in degassed DMSO) upon 365 nm irradiation for 60 s and 385 nm irradiation for 220 s, respectively. (C) Plot of the change in absorption at λ = 365 nm during 365/385 nm irradiation cycles starting with (E)-1 (2.5 × 10–4 M in degassed DMSO).
