摘要： 对不同组分的Ru(dpphen)32+[简称Ru(Ⅱ)]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,并且在可见光范围内具有很强的吸收及发射峰的功能膜.

关键词: LB膜, 钌有机螯合物, 吸收与发射光谱, 小角X光衍射

Abstract: The mixed monolayers of Ru(dpphen)32+ (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 LBfilms. Characterized by optical spectra and low angle X-ray diffraction, the mixed LBfilms, which have strong absorption and emission in visible region, are regular, homogenous and have a good multilayer structure.

Key words: LB films, Ruthenium complex, UV-Vis spectra and emission spectra, Low angle X-ray diffraction
