二分子膜の規則構造による発色現象とその固定化

Iridescent aqueous solutions of three types of surfactant have been studied. They are anionic alkenylsuccinic acid (ASA), cationic dimethyldioctadecylammonium chloride (DOAC), and nonionic dodecyl glyceryl itaconate (DGI) with small amount of ionic surface active substances. The structure of iridescent ASA solutions has been studied mainly by UV and X-ray diffraction techniques. The results indicate that the iridescent solutions of ASA consist of a lamellar liquid crystal having the spacing distance of submicrometer and the iridescent color appears by the interference of reflected light by single bilayer membranes. The drastic blue-shift in reflection spectra of DOAC can be observed when the iridescent liquid crystal transforms into the gel phase on cooling. The iridescent structure of polymerizable surfactant, DGI, can be immobilized inside the hydro-gel by copolymerization with acrylamide and N, N'-methylenebis (acrylamide).
