Triplet Charge Transfer Complex between Excited Electron Acceptor and Ground State Electron Donor

Abstract

The half-wave reduction and oxidation potentials, E1/2's, of carbonyl compounds and amines, respectively, are used to estimate the location of triplet charge transfer states (CT). A linear free-energy relationship between the calculated CT triplet energies and the corresponding carbonyl molecules triplet energies was obtained. It has also been found that the free energy change (ΔF) for CT complex formation correlate with the triplet carbonyl quenching rate constant kq.
