Study on the synthesis and photoconductivity of bisazo compounds having 1,3,4-oxadiazole

The bisazo compounds were prepared by coupling diazotized 2,5-bis(4-aminophenyl)-1,3,4-oxadiazole with 3-hydroxy-N-phenyl-2-naphthalenecarboxamide (Naphthol AS) and its derivants. These compounds were analysed by IR spectra and element analysis. The X-ray diffraction patterns were used to determine their crystal structure. The relationships between treatment methods and crystal structures of the compounds, and the effects of crystal structure on photoconductivity were also studied.
