SYNTHESIS, PHOTOCONDUCTIVITY AND ELECTROOPTICAL PROPERTIES OF DISPERSE RED-1 BONDED PVK

Polyvinylcarbazole was chloromethylated then condensed with Na salt of Disperse Red-1. The produced new polymer, Disperse Red-1 bonded PVK ( PVK-DR1) was characterized. The photoconductivity and electro-optical coefficient were measured using a thin film fabricated from the polyme r. The result shows that the film is photoconducting electro-optical a ctive. The photoconductivity is electric field dependent. When the app lied voltage was 100 to 200 mV/M, the photocurrent was 1 to 188 nA, an d photoconductivity was 6 to 241X10(-13) S . cm(-1), quantum efficient was 0.18% to 5%. Electro-optical efficient was 1 . 3 pm/V.
