Molecular complexes of paraquat with anilines

摘要: The U V-VIS spectra of molecular complexes paraquat with ring and N-substituted anilines have been recorded in methanol 50% v/v aqueous methanol. All the exhibited well-resolved charge transfer bands wavelength region where neither components any absorption. energies substituted aniline-paraquat bear linear relationships ionization potentials obtained from aniline-TCNE complexes, indicating π - interaction between donors. Both N-substituents effects on positions CT as well stabilities complexes. are shifted to shorter wavelengths decrease going aqueous.
