合成了[1,6-双(1′-苯基-3′-甲基-5′-吡唑啉酮-4′]-己二酮[1,6]合稀土(La,Dy)酸(E)-N-十六烷基-4-(2,4′-二甲氨基苯基)乙烯基吡啶两个新的稀土配合物.用元素分析、紫外可见光谱、红外光谱、差热热重谱、X射线粉末衍射、核磁共振谱和摩尔电导测量对配合物进行了表征.空气-水(18℃,pH5.4)界面上的表面压-面积(π-A)等温线研究表明,两配合物的Langmuir成膜性明显优于半菁溴化物和碘化物.二次谐波发生(SHG)实验测得镝配合物的二阶分子超极化率β为4.8×10~(-48)Cm~3V~(-2),较半菁碘化物大约3.4倍.
(La, Dy) (1, 6-bis (1’-phenyl- 3’- methyl- 5’-pyrazolone- 4 ’ E) -N-hexadecyl-4- (2,4’-dimethylaminophenyl) vinylpyridine.Using elemental analysis, UV-visible spectrum, infrared spectrum, The complex was characterized by X-ray powder diffraction, X-ray powder diffraction, nuclear magnetic resonance spectroscopy and molar conductance measurements. The surface pressure-area (π-A) isotherm at air-water interface (18 ℃, pH 5.4) The Langmuir film formation property of the complex is better than that of the half-cyanine bromide and iodide.The second-order molecular hyperpolarizability β of the dysprosium complex measured by the second harmonic generation (SHG) experiment is 4.8 × 10 ~ (-48) Cm ~ 3V ~ (-2), about 3.4 times more than half-cyanine iodide.
