Abstract

Photoinduced electron transfer (ET) reactions in pyrene/alkali-metal/THF solutions were studied by Fourier transform EPR. Different spin polarization effects are associated with the ET reactions, i.e. ST₀, ST_-, F-pair and correlated radical-pair mechanisms. It is demonstrated how the spin dynamics are controlled by the specific alkali-metal ion, its solvation in neat THF and the presence of a chelating agent (cryptand). Experiments were carried out using Li, Na, and K.
