ELECTRONIC-STRUCTURE OF PLASMA POLYMERS OF QUINOLINE

Thin solid films were prepared by the plasma polymerization of quinoli ne in order to obtain polymeric films with a highly conjugated pi elec tron system. The electronic structure of these plasma polymers was cha racterized in situ by ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS) and by ex situ Fourier transfo rm infrared (FTIR) spectroscopy. The films were doped by iodine and th e doping mechanism was analysed by UV-visible and FTIR spectroscopy an d electrical resistance measurements. A comparison of the electronic s tructure and electrical properties of these plasma polymers with those of plasma polymers of pyridine and benzene was performed.
