Abstract

Long-range interactions over 50 Å allow electron exchange to proceed in a series of conformationally constrained Ru/Os polypyridine complexes (see picture). The dynamics of the intramolecular electron exchange indicate that the connecting 1,4-diethynylated-2,5-dialkoxybenzene units act independently as superexchange mediators. Even with five such units linked together there is no indication for the population of a connector-based triplet state.
