| Abstract: | A novel compound 5-(4-hexadecyloxy-phenylazo)-1,3-phenyl-di(1,3,4-oxadoazoleyl sulfur) methyl acetate was synthesized with isophthalic acid as raw material.Structures of intermediates and target compound were characterized by IR,UV-vis,1H NMR.The azo structure in 5-(4-hexadecyloxy-phenylazo)-1,3-phenyl-di(1,3,4-oxadoazoleyl sulfur) methyl acetate took place trans-cis photoisomerization under 365 um UV irradiation.In the photostationary state,the efficiency of trans-cis photoisomerization(R) and the content of cis-isomer(Y) of azo chromophore were 80.95% and 84.99%,respectively.The rate constant of photoisomerization(kp) was 1.3389 min-1. |
