Stable anions formed by organic molecules substituted with superhalogen functional groups

The concept of rendering the electronically unstable anions stable is presented for the arbitrary chosen organic molecules whose inability to form bound electronically stable anionic states is well established. It is shown that introducing a superhalogen-like substituent to either ethane, ethylene or benzene results in obtaining a molecule that binds an excess electron relatively strongly. The electronic stabilities of such resulting daughter anions are always positive and large (4.09–6.66 eV). Instead of considering the species studied as the organic molecules substituted with the superhalogen-like substituents and the excess electron attached, one may alternatively view them as the structurally modified superhalogen anions having one ligand replaced with the hydrocarbon group.
