Progress in Research on Photoactive Azobenzene Self-assembly Monolayers

Recently,the research on materials focuses on precision and controllable,and materials which are sensitive to external fields have become the research hot spot.Because of the reversible photoisomerization characteristics of azobenzene and its derivates under UV-Vis irradiation,the azobenzene self-assembly monolayers(SAMs) is attracting much more attentions of researchers.The photoisomerization and the varieties of performances during the photoisomerization process of azobenzene molecules are introduced.Then the factors which have effects on the photoisomerization rate of azobenzene are detailed.At last,the applications and research progress of azobenzene self-assembly monolayers in the many fields at home and abroad are summarized,such as optics,surface chemistry,chemical separation and biological medicine pharmacy,etc.
