摘　　要：对不同组分的 Ru(dpphen) 2 + 3 [简称 Ru( ) ]与花生酸 (AA)在纯水亚相上的混合单分子膜的相容性、分子间相互作用以及凝聚单分子膜的结构进行了研究 .成功地将这种功能单体分子膜转移到固体载片上 ,制备成混合 LB膜 .紫外 -可见光谱、发射光谱及小角 X光衍射表明这种混合 LB膜是一种稳定、均一、具有良好的层状结构 。The mixed monolayers of Ru(dpphen) 2+ 3(dpphen=4,7 diphenyl 1,10 phenanthroline)[abbreviated as Ru(Ⅱ)] and arachidic acid(AA) in different molar proportions on pure water interface had been studied. The miscibility, molecular interaction of the two components and structure of condensed mixed momolayers were investigated in details. The monolayers were successfully transferred onto solid substrate and form functional mixed LB films. Characterized by optical spectra and low angle X ray diffraction, the mixed LB films, which have strong absorption and emission in visible region, are regular, homogenous and have a good multilayer structure.
