Photoinduced Electron Transfer in Ionic Media

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...

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...

Photoinduced electron transfer and multiple states mechanisms

Results of our ps-fs laser photolysis studies on interactions between unlinked D(donor)-A(acceptor) systems in luminescence quenching reactions and reaction dynamics of produced transient CT (charge transfer) or IP(ion pair) states and also on some D-A systems linked by flexible chains or directly can be interpreted satisfactorily by considering the formation of multiple CT and/or IP states wit...

Photoinduced Electron Transfer in Langmuir-blodgett Films

Photoinduced electron transfer from an excited donor molecule (oxacyanine) to an acceptor molecule (viologen) located at the same interface in monolayer assemblies has been studied by measuring steady state fluorescence quenching and the excited state decay of the donor molecule. Donor and acceptor molecules are incorporated in matrix monolayers of arachidic acid and methyl arachidate, with a m...
