On the nature and extent of intermolecular interactions between entrapped complexes of Ru(bpy)sub3 supra2+ in zeolite Y

Article Abstract:

A study relating to research on polypyridine complexes of divalent ruthenium was conducted to investigate the interactions between the zeolite entrapped Ru(bpy)sub3 supra 2+ molecules as a function of loading. The study ensured that complete complexation occurred. Experimental results indicate that Ru(bpy)sub3 supra 2+ can be incorporated into Y-zeolite at high concentrations up to 0.46 mol dm-3 , 1 Ru/1.9 cages, without significant contamination by reaction intermediates or starting materials.

Effect of surface immobilization on intramolecular and intermolecular electron transfer in a chromophore-donor-acceptor assembly

Article Abstract:

The properties of a chromophore-donor-acceptor assembly adsorbed on the surface of nanocrystalline ZrO2 were studied by emission and transient absorption spectroscopy. Evidence was found for relatively unperturbed MV(super +.) -> PTZ(super +.) intramolecular back-electron transfer, as well as a much slower component arising from MV(super +.) -> PTZ (super +.) intermolecular electron transfer between spatially separated adsorbed molecules on the surface.
