Photoinduced Charge Separation: Towards the Design of Supermolecular Systems Based on Transition Mects of electron transfer kinetics and inter- valence transfer spectroscopy that are relevant to the problem are discussed. Studies in which several metal-containing moieties are linked via cyanide bridges to the Ru(bpy).. chromophore are reviewed, and strategies for future work are outlined.

Fundamental Studies Into Primary Events in Photocatalysis Employing CdS and TiO2 Semiconductors: Phn the photo-oxidation of alcohols and of carboxylate compounds, among others. These materials are the n-type CdS and TiO.. Many of the processes are carried out with powders. Unfortunately, powder dispersion, where the particles have sizes ≳ 2 μm, are not amenable to studies that might lead to an un

Electronic Spectroscopy of Semiconductor Clusters,ctronic states are characterized via . absorption and luminescence spectroscopy. The clusters, although crystalline, are too small to have the bulk semiconductor band gap. The physical nature of their electronic states is discussed.

Catalysed Decay of Oxidising Radicals in Water,py Ru ., porphyrin π-radical cations and oxidised prometh-azine. Most of the radicals are unstable with respect to dispropor- tionation, although the timescalė for this deactivation varies enormously. Addition of colloidal Ruo.2H.o or Prussian Blue, both reasonable 0. — evolving catalysts, can enhan

Photocatalysis and Light-Induced Electron Transfer Reactions of Tertiary Amines,ion reactions between indigoid dyes — thioindigo, N.N’diacetylindigo and oxalylindigo — with triethylamine are described. The amine is readily oxidized to a radical cation which, in turn, is easily deprotonated to give a relatively good electron donating free radical. A sequence of electron-proton-e

Spectroscopic and Electrochemical Studies of Photochemical Electron Transfer in Linked Donor-Acceptin S. state, probably undergoes intramolecular electron transfer to produce the charge-separated state P†Q. The forward rate constant . at 295 K for this electron transfer, measured from fluorescence quenching in PAQ (Scheme 1) compared with its hydroquinone analogue PAQH., lies in tne range (1 − 23

Linear Chain Platinum Complexes as Photocatalysts,fram’s Red Salt Cl.•4H.O were examined as a potentially important new class of low bandgap materials for solar fuel synthesis. Room temperature emission and lifetime measurements on two mixed valence red salts provide evidence for mobile excitonic states at or near the bandga
