Abstract

We have investigated properties of poly(9-vinylcarbazole) (PVK) doped with 30% wt 4-dibutylamino-4'-nitrostilbene (DBANS), depending on orientation of the polar DBANS molecules. Appearance of the orientation-induced built-in electric field was proven optically by the solid electric field induced second harmonic generation and electrically by the current-voltage characterization. Modification of optical properties was evidenced by the spectral dependencies of the absorption coefficient. The thermally stimulated current spectra had demonstrated that carrier transport and trapping are affected, too.
