Abstract：Four kinds of azobenzene compounds(1~4) containing nitro, amino, and different number of azo groups were synthesized by diazo coupling reaction from aniline or 4-nitroaniline. The structures were confirmed by 1H NMR and FT-IR. The UV-Vis spectra of 1~4 under UV irradiation were investigated. The results showed that the photoisomerization rate of the compounds linked with electron-donating group(NH2) was faster than those linked with electron withdrawing group(NO2). The photoisomerization was therefore restrained by NO2. The cis/trans isomerization process was also affected by the number of azo couples.
