Controlling the Direction of Photoinduced Energy Transfer in Multicomponent Species

Abstract

The direction of the efficient photoinduced energy transfer which takes place in two new multicomponent species that contain RuII-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.
