摘要

Six bisazo compounds were synthesized by coupling 2-(4′-aminophenyl)-6-aminobenzoxazole as diazo component with -phenyl-′-(2-hydroxy-3-naphthoyl)urea derivatives, and characterized by ultraviolet and visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FT-IR) and elemental analysis (EA). Using these bisazo compounds as charge generation materials and CT-191(2-methyl-4-(-dibenzyl)aminobenzoaldehyde-1,1-diphenylhydrazone) as charge transportation material, organic photoconductive devices were prepared. The result from photoconductivity measurement of the devices shows that the bisazo compound from -(2-methylphenyl)-′-(2-hydroxy-3-naphthoyl)urea has the best xerographic performance, = 600 V, = 30 V, = 15 Vs, = 3.5 lxs.
