Ultraviolet photoelectron spectroscopy and oxidative electrochemistry of 8-hydroxyquinoline and its derivatives

Abstract The gas-phase ionization potentials of 8-hydroxyquinoline and several of its alkyl derivatives in the region 8–12 eV are assigned. The energies of the highest occupied molecular orbitals and the half-wave oxidation potentials at a rotating platinum electrode are used to derive empirical values for differential solvation energies for the compounds in acetonitrile and dichloromethane solution.
