Abstract: | The electrical and luminescence properties of a poly(amidoamine) (PAMAM) dendrimer containing naphthalimide are investigated. The influence of adsorbed oxygen on the electrical conductivity of thermally evaporated organic films is analyzed using cyclic thermal desorption. The results obtained are interpreted within a model of two-level hopping electron transfer according to which one of the two systems of energy levels corresponds to intrinsic states of electrons in PAMAM molecules and the other system is associated with the states of electrons in adsorbed oxygen molecules. The use of the cyclic thermal desorption method in combination with the proposed model makes it possible to estimate the localization length of electrons numerically and to determine the states involved in hopping electron transfer. It is demonstrated that the studied compound in the solid state possesses a high luminescence power over a wide spectral range. |
