摘　　要：A new difunctional photorefractive model molecule, 3 azo 4′ nitro 9 ethyl carbazole was synthesized and its structure was characterized by 1H NMR and UV spectra. The results from Time of Flight experiment show that the sample exhibited good photoconductivity not only by hole transport but also by electron transport, which may be due to the reason that the molecule formed not only a delocalized system but also charge transport complex, and contributed to its charge carrier mobility.A new difunctional photorefractive model molecule, 3 azo 4′ nitro 9 ethyl carbazole was synthesized and its structure was characterized by 1H NMR and UV spectra.
