Photoinduced electron transfer in supramolecular assemblies composed of one-shell and two-shell dialkoxybenzne-tethered Ru(II)-tris(bipyridine) derivatives and a bipyridinium cyclophane

The photoinduced electron transfer quenching pathways in supramolecular assemblies of dialkoxybenzene-tethered Ru(II)-tri(bipyridine) derivatives were analyzed to characterize the resulting products. Analysis of the supramolecular assemblies with two-shell dialkoxybenzene-tethered Ru(II)-tris(bipyridine) indicated the absence of an additive effect in the association of the electron transfer units of BXV4+. The pi-donor-acceptor interactions between the bipyridinium cyclophanes also mediated the synergetic association of BVX4+ to the two-shell functionalized sensitizer.
