Light, air, and heat suffice to flip a molecular switch. In their Communication on p. 7689 ff., T. Linker et al. show that oxidation of ortho ‐substituted bisarylanthracenes with singlet oxygen results in axial rotation by 180°. After cleavage of oxygen under mild conditions, the trans isomer can be regenerated by thermolysis. The full switching process requires only three steps, and oxygen is the only side product.
