Fig. 2. (A) Absorption spectra of Z and E-diazocine (after 385 nm excitation) and the photoswitching system consisting of diazocine, PtOEP and PdTPNP. The color bars indicate the excitation wavelengths to drive the triplet sensitized isomerization in both directions. (B) Diazocine photoswitching curve as the conversion percentage of E-diazocine monitored by absorption at 500 nm. The colored areas indicate time under excitation.
