| 摘 要： | 采用界面吸附法制备了５种十八／杂多阴离子杂化ＬＢ膜ＯＤＡ／ＨＰＡ（ＨＰＡ＝ＰＷ１２，ＰＭo12,MPo12,PW6Mo6,PW9Mo3,P2Mo18).对５种本合物在空气／水界面上单分子膜的行为进行了研究，它们有较高的崩溃压４６．０－４８．０mN,m^-1，均能开稳定的单分子膜，用红外光谱，紫外光谱，小角Ｘ射线衍射（ＬＸＲＤ）和荧光光谱对ＬＢ膜的沉积特性与结构进行了鉴定，结果表明，制备的ＬＢ膜具有中心对称性，其层状结构由杂多阴离子的单层与表面活性剂双层交替组成。

| Abstract: | LB films of five new hybrid octadecylammonium / heteropolyanions ODA/HPA(HPA = PW12, PMo12, PW6Mo6, PW9Mo3, P2Mo18) were prepared and characterized by π--A isotherms, FT-IR spectra, UV-Vis absorption spectra, Low-angle X-ray diffraction(LAXD) and fluorescence spectra . The results show that they have good film-forming property, on the air/water interface. The collapse pressure is 46.0 ～48.0mN · m-1, the monolayer and multilayer thus prepared have good stability. The lamellar structure so obtained consists of monolayers of the heteropolyanions alternating with bilayers of the organic surfactant(centrosymmetric LB film) |
