【摘要】 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^-48Cm³V^-2,较半菁碘化物大约3.4倍.更多还原

【Abstract】 Two novel rare earth coordination compounds, (E) - N - hexadecyl - 4 - (2-4’ -dimethylaminophenyl)ethenyl pyridinium 1,6- bis - (1’ - phenyl - 3’ - methyl - 5’ - pyrazolone - 4’)hexanedione[1, 6] lanthanum - dysprosium( III) have been synthesized and characterized by elemental analysis, UV - Vis, IR, 1H NMR, TG - DTA analysis, X - ray power diffraction and molar conductivity. The comparisn of the surface pressure - area isothems of the comlexes with those of hemicyanine bromide and iodide is made. The Langmuir film - forming properties of the metal complexes are superior to the hemicyanine bromide and iodide. Second - harmonic generation from monolayer film of the dysprosium complex shows that the second - ordermolecular hyperpolarizability to be 4.8×10 -48C m3 V-2.更多还原
