【摘要】 采用界面吸附法制备了 5种十八胺 /杂多阴离子杂化 LB膜 ODA/HPA（ HPA=PW12， PMo12， PW6Mo6， PW9Mo3， P2Mo18）。对 5种配合物在空气 /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，均能形成稳定的单分子膜。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单层与表面活性剂双层交替组成。更多还原

【Abstract】 ： LB films of five new hybrid octadecylammonium / heteropolyanions ODA/HPA(HPA=PW12, PMo12, PW6Mo6, PW9Mo3, P2Mo18) were prepared and characterized byπ-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).更多还原
