exhibit different physical properties (e.g., melting points and solubilities) and interconversion by rotation around the aryl-aryl axis commences at <100 degrees C for fluoro-substituted diarylanthracenes and at >300 degrees C for alkyl- or alkoxy-substituted diarylanthracenes. The reactions with singletoxygen were studied separately and revealed different reactivities and reaction pathways. The yields

Two different reaction pathways in the photooxygenation of 9,10-diarylanthracenes are identified, with strong evidence for polar (forward, singlet oxygen addition) and radical (backward, thermolysis) intermediates.
