Fig. 5. (a) Time-evolution of UV-vis spectra of ADPA in the presence of HM-RB under irradiation. Inset: normalized absorbance changes of ADPA at 378 nm vs. irradiation time for an air-equilibrated suspension of HM-RB (red), in comparison to the same sample in the absence of oxygen (black). (b) Time evolution of absorbance at 378 nm over different periods on anthracene endoperoxide thermolysis. Inset: UV-vis spectra of ADPA after different heating time at 80 °C. Irradiation was carried out with the irradiation setup I.
