영문 초록

The absorption spectra of synthesis of long chain fatty acid containing azobenzene start from p-(p -hydroxy phenyl azo)-benzoic acid was investigated by ultraviolet spectrophotlmetery in chloroform solvent at the various temperature. In addition, The pressure-area of the water-air interface was obtained and the LB film was fabricated onto a quartz slide and quartz crystal by conventional Langmuir-Blodgett(LB) method. The UV absorption spectra of Langmuir-Blodgett(LB) film on quartz slide and spectrum of monolayer formed on quartz crystal have been measured. Long chain fatty acid containing azobenzene are induced phoisomerization by the application of u. v. and visible light irradiation alternatively the reversibility of photoisomerization was more clear difference when the number of C_n increased but, not so good at C_14-azo. At the pressure-area isotherms, the value of surface pressure increment were decreased when the number of C_n increased. A surface pressure of 20mN/m was obtained as a proper one for a film deposition. The photoismerization at LB films were induced by application of UV and visible light irradiation alternatively. So the LB film of long chain fatty acid containing azobenzene has possibility to being applied to functional molecular devices such as photomemory and light switching.
