“…In order to eliminate the unwanted back-reaction from acceptor to donor, both the donor and acceptor can be immobilised on supporting media, as for example colloidal silica particles (Ref. 82,83). The negatively charged surface groups of the colloidal silica repel the propylviologen sulfonate (PVS) radicals from the ruthenium complex adsorbed on the surface (Ref.…”

“…For example, a change in mobility and average distance between the donor and acceptor molecules upon coupling to a solid surface has been utilized to control photoinduced electron and energy transfer reactions. [32,[34][35][36] Similar composite systems based on semiconductor colloids were also used for the construction of a new type of photochromic device [5] and for obtaining a long-lived charge separation on a nanostructured TiO 2 membrane. [37] A composite model system which consists of a molecular donor/acceptor pair coupled to the surface of metal oxide nanoporous films is proposed to study the contribution of the surface trap states and their influence on the interfacial ET as well as charge trapping and spatial diffusion processes in films.…”

“…This agrees with previously reported values in solution. [59][60][61][62] No other study has reported the quenching in the presence of PSS. We observe that lifetime and intensity data give identical plots in water, but diverge in the presence of PSS.…”

“…[Ru(bpy) 3 60 However, the cage escape yield was slightly reduced (B0.10) upon addition of PSS. The drop in cage escape yield for noncovalently bound [Ru(bpy) 3 ] 2+ may be connected with the static quenching observed for this system, since reverse electron transfer could be efficient if the reactants are held fixed in close proximity and attract each other.…”
