The cover picture shows two energy‐transfer dyads that both comprise a ruthenium donor and an anthracene acceptor. The time constant ( τ ) associated with the energy transfer process is strongly dependent on the linkage between the donor and the acceptor: A salt bridge mediates energy transfer with τ = 153 ns, while a covalent p ‐xylene linker makes energy transfer possible within less than 10 ns. Details are discussed in the article by J. C. Freys and O. S. Wenger on p. 5509 ff.
