| 摘要: 合成了八-4-(四氢糠氧基)酞菁铕(Ⅲ),通过元素分析、红外光谱、质谱和紫外 可见光谱加以确认。测定了配合物的Π-A曲线,证明它有很好的成膜性,Z型沉积形成的LB膜材料有很强的荧光响应,随着LB膜厚度的增加,荧光性增强。掺杂邻菲咯啉形成的混合LB膜,其荧光性比纯膜强。但不是邻菲咯啉加入的量越多荧光性越强。配合物∶邻菲咯啉=1:10时（摩尔比）,有最好的荧光行为。用电子光谱对LB膜的结构进行了表征。 |

| Abstract: Eu(Ⅲ)-octa-4-(tetrahydrofurfuroxy)phthalocyanine (EuPc2′ ) was synthesied and characterized by elementary analysis、 IR、 MS、 UV-vis spectra. EuPc2′ has good film-forming ability from determination of isotherm of π-A. The complex LB film was formed by depositing of EuPc2′ on a quartz slide with the LB techniques of the Z-type. The luminescent properties of pure and doped LB films were determined. The results showed that pure films have good luminescent properties, the thicker the LB films, the stronger the fluorescent intensity. The films doped with o-phenanthroline (abbreviated as phen) made the relative intensity of fluorescent emission behavior enhance in comparison to that of pure LB film. But the amount of phen may be not too much . Our results showed that EuPc2′ :phen = 1∶10 (molar ratio )has the best fluorescent behavior. The electronic spectroscopic characterization of the LB films is also given. |
