Double up : Photochemical upconversion by MLCT‐sensitized triplet–triplet annihilation is demonstrated (MLCT=metal‐to‐ligand charge transfer). Selective visible excitation of [Ru(dmb) 3 ] 2+ (dmb=4,4′‐dimethyl‐2,2′‐bipyridine) in the presence of anthracene efficiently produces the [4+4] cycloaddition product. This transformation traditionally requires ultraviolet light.
