Dynamics of Bimolecular Photoinduced Electron-Transfer Reactions
From the accumulated results of several research groups over the last 25 years, it is clear that photoinduced electron-transfer reactions have significantly broadened the scope of organic photochemistry.1 The fundamental mechanistic principle is that when quenching of an excited state via electron transfer is sufficiently exothermic, the reaction occurs at or close to the diffusion-controlled l...

Title of Document: PHOTOINDUCED ELECTRON TRANSFER IN IONIC MEDIA Rebecca Cristine Vieira, Doctor of Philosophy, 2008 Directed By: Dr. Daniel E. Falvey, Department of Chemistry and Biochemistry The goal of this research was to explore the use of room temperature ionic liquids (RTILs) and ionic liquids crystals (ILCs) as reaction media for photoinduced electron transfer (PET) processes. Photoindu...
متن کاملBimolecular photoinduced electron transfer in imidazolium-based room-temperature ionic liquids is not faster than in conventional solvents.
The fluorescence quenching of 3-cyanoperylene upon electron transfer from N,N-dimethylaniline in three room-temperature ionic liquids (RTILs) and in binary solvent mixtures of identical viscosity has been investigated using steady-state and time-resolved fluorescence spectroscopy. This study was stimulated by previous reports of bimolecular electron transfer reactions faster by one or several o...
متن کاملBimolecular photoinduced electron transfer reactions in liquids under the gaze of ultrafast spectroscopy.
Because of their key role in many areas of science and technology, bimolecular photoinduced electron transfer reactions have been intensively studied over the past five decades. Despite this, several important questions, such as the absence of the Marcus inverted region or the structure of the primary reaction product, have only recently been solved while others still remain unanswered. Ultrafa...
متن کاملultrafast spectroscopy on bimolecular photoinduced electron transfer reactions
in Figure 1. After excitation of one of the reactants, diffusion is required to bring the reaction partners at distances where charge separation (CS) can occur. The nature of the primary quenching product is still debated.3 For weakly exergonic CS, ∆GCS > ~ -0.4 eV, it is generally accepted that the product is a contact ion pair (CIP), that is, two ions at a distance enabling a substantial over...
