Azo Molecules In The Functional Synthesis And Interfacial Assembly Nature

The LB films of photochromic materials are of interest as possible high density information storage media and light switching devices. Azo-chromophoric group are a typical candidate for functional LB films. Whereas, some researchers have found that the trans-cis photoisomerization was restricted, when introducing azobenzene derivatives into the LB films, due mainly to the limitation of space.In this thesis, we focus on synthesizing and characterizing a series of azobenzene-containing amphiphiles. By electrostatic force, we got the complex of the compound we synthesized with DODA surfactant. We delved on their aggregation behavior at air/liquid interface by n -A isotherms and BAM images. We also produced Y-type LB films of the complex on CaF2 plate and investigated the films by UV irradiation, FT-IR and polarized UV.We discovered that we not only successfully introduced the azo-chromophoric group into the LB films by the electrostatic force, but also produced a kind of LB film where the part of the azobenzene are of isotropy. Thus, the azo-chromophoric group are given enough room for photoisomerazation.
