Electron Affinity of Organic Molecules

Abstract

Abstract The formation of organic radical ions by direct electron exchange between a donor molecule D and an acceptor molecule A is becoming increasingly important, particularly with regard to reaction mechanisms involving intermediate radical ions. All redox processes also involve electron exchange. Finally, the knowledge of electron affinities and ionization energies of organic molecules is necessary for a quantitative theoretical interpretation of intermolecular resonance and of the semiconductor properties of crystalline organic compounds and molecular compounds.
