摘要： 合成了4种含半菁的新型稀土配合物:四(1-苯基3-甲基-4-苯甲酰基吡唑啉酮-5)合稀土(La,Nd,Dy,Yb)酸(E)-1-十六烷基-4-(2,4'-二甲氨基苯基)乙烯基吡啶。用元素分析、紫外可见光谱、红外光谱、核磁共振谱、差热热重谱、X射线光电子能谱、X射线粉末衍射和摩尔电导对配合物进行了表征。研究了4个配合物的空气-水(18℃,pH=5.6)界面上的表面压-面积(π～A)等温线行为和镝配合物单层Langmuir-Blodgett膜的二次谐波发生(SHG)性质。

Abstract: Four novel rare earth coordination compounds,(E)-hexadecyl-4-(2,4-dimethylaminophenyl)ethenyl pyridinium tetrakis-(1-phenyl-3-methyl-4-benzoylpyrazolonato)lanthanide(Ⅲ)(La, Nd, Dy, Yb) have been synthesized and characterized by elementary analysis, UV-Vis, IR,1HNMR,TG-DTA analysis,X-ray photoelectron specroscopy,X-ray powder diffraction and molar conductivity. The comparison of the surface pressure-area isotherms of the complexes with that of hemicyanine, bromide is made. The better Langmuir film-forming properties of the metal complexes are obtained. Preliminary result of second harmonic generation (SHG) from monolayer film of the dysprosium complex is reported.

Key words: Lanthanide coordination compound, Hemicyanine, Langmuir-Blodgett film, Second-harmonic generation
