영문 초록

The Synthesis of azobenzene containing long chain fatty acid and poly vinyl alcohol by esterification reaction(Cn-Azo-PVA) was optimized, starting from p-(p -hydroxy phenyl azo)-benzoic acid and the product of reaction containing azobenzene chromophores was investigated by ultraviolet spectrophotometery in toluene solvent at room temperature. In addition, UV absorption spectra of Langmmuir Blodggett(LB) film deposited on quartz plate have been measured and the structure of these compounds were ascertained by means of Ultraviolet and FT-IR. Recrystallization of reaction product in the solvent results the experimental yield obtained about 22.27% p-(p -octadecyloxy phenyl azo)-benzoic acid-poly vinyl alcohol. Long chain azobenzene derivative-poly vinyl alcohols are induced phtoisomerization by u. v. and visible light irradiation. The LB film of azobenzene containing long chain fatty acids (C₁₈-Azo-PVA) are possible of being applied to functional molecular devices such as photomemory and light switching.
