In studying electrical conduction of nitrated poly(N‐vinylcarbazole) (PNVC), several homodispersed samples of PNVC were nitrated by using two different nitration methods, resulting in mononitrated and dinitrated PNVC, respectively, with a really distinct polymer bulk structure which is responsible for the response of the charge carriers to an applied electric field. Electrical behavior in mononitrated PNVC is due to charge transfer complexes, while in dinitrated PNVC it is due to a dipole orientation effect.
