Three anthracene rings connected by m-phenylene spacers with hydroxy groups generate isolable trans- and cis-atropisomers whose interconversion is solvent sensitive and can be activated at room temperature by an external stimulus (base).

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.
