The direction of the efficient photoinduced energy transfer which takes place in two new multicomponent species that contain Ru II ‐polypyridine chromophores and anthracene subunits is controlled by the temperature. The switch in the direction of the energy‐transfer process arises from the quite different intrinsic lifetimes of the luminophores and the relatively small energy gap between the lowest energy excited states located in each subunit. Novel molecular‐level devices based on this particular effect are foreseen.
