摘要

Azobenzene molecules show excellent application potential in many fields due to their photoisomerization properties.Azobenzene molecules will gradually change from trans-structure to cis-structure under the irradiation of UV.In this paper,we have synthesized 4,4'-dibromoazobenzene molecules and characterized their photoisomerization properties.We found that with the extension of UV time,the trans absorption peak at 343 nm decreased significantly,while the cis absorption peak at 435 nm showed an upward trend.Furthermore,photoisomerization of azobenzene is not a first-order reaction.
