摘要：
(Chemical Equation Presented) Singlet oxygen fuels anthracenes and forces an axial rotation of aryl substituents during the oxidation. The molecular switch can be synthesized in only one step from commercially available starting materials. Thermal cleavage of the resulting endoperoxides proceeds quantitatively and affords a simple 180° switch with oxygen as the only waste product. The initial trans state is attained by heating, and repetitive cycles are possible. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
