Electron Transfer Processes

Cyclic voltammetry has revealed four reversible single electron transfer processes in the oxidation and reduction of diphenylpicrylhydrazyl (DPPH) in tetrahydrofuran (THF). These are associated with a cation, a free radical, a monoanion, a dianion radical, and a trianion of DPPH.THF is a good solvent for cyclic voltammetry as evidenced by the stability of the products generated at the electrodes. It is also one of the few excellent solvents for anionic polymerization and is therefore a remarkably suitable medium for studies of electropolymerization phenomena.
