主　　题：charge generation material naphthoylurea benzoxazole bisazo compounds photoconductivity 

摘      要：Six bisazo compounds were synthesized by coupling 2-(49-aminophenyl)-6-aminobenzoxazole as diazo component with N-phenyl-N9-(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-(N,N-dibenzyl)aminobenzoaldehyde-1,1-diphenylhydrazone)as charge transportation material,organic photoconductive devices were *** result from photoconductivity measurement of the devices shows that the bisazo compound from N-(2-methylphenyl)-N9-(2-hydroxy-3-naphthoyl)urea has the best xerographic performance,V_(0)=600 V,V_(R)=30 V,R_(d)=15 V·s^(-1),E_(1/2)=3.5 lx·s.
