54. The fact that processes 3 and 3′ of Figure 4, that is, the reduction of the inner bridges, take place simultaneously could appear anomalous. In fact, the process is the reduction of (identical) ligands connected to the same metal center, and it is known[4] that such types of processes are commonly split in Ru(II) polypyridine complexes, because of ligand-ligand interactions mediated by the shared metal center. However, it has already been reported that the reduction of outer ligands in multicomponent metal complexes similar to 1 destabilizes the LUMO of the inner bridges, substantially increasing their energy gap with the metal-centered orbitals.[14] Since ligand-ligand interactions are largely governed by such energy gaps,[12-14] coalescence of the inner bridge reduction of 1 is justified.

56. 2 moiety.
57. Both exoergonic electron hopping[20] and energy transfer between directly connected subunits of the type present in 1[7,8] are known to take place in the femtosecond timescale in ruthenium(II) polypyridine complexes. In the present discussion, only triplet states are considered to be present after the laser pulse (in our case, 0.6 ps), since intersystem-crossing (ISC) processes in Ru(II) polypyridine complexes are reported to be faster than 200 fs,[7,8,20-22], except in paiticular cases.[23]

64. Some evidence for this ultrafast energy-transfer process is found in kinetic traces in the 500-540-nm range, showing transient bleaching that recovers in 450 fs.
65. Thermally accessible metal-centered states might also play some role in such processes.
66. Actually, the 560-nm decay is not single exponential. A shorter component of 0.35 ps can be attributed, as in the model compound 5, to vibrational cooling.
67. This finding implies an ultrafast charge-separation process ET(1), which occurrs within 0.6 ps.
