| 摘 要： | 合成了四(α-噻吩甲酰三氟丙酮)合稀土(La,Nd,Dy,Yb)酸(E)-N-十六烷基-4-2-(4-二乙氨基苯基)乙烯基]吡啶四个新的稀土配合物。用元素分析、紫外可见光谱、红外光谱、小角X射线衍射、差热-热重分析和摩尔电导对配合物进行了表征。研究了它们的表面压-面积(π-A)等温线行为。研究结果表明它们具有良好的成膜(Langmuir)性能, La, Nd, Dy和Yb配合物零压分子平均截面积A~π~→~0分别为1.94,1.93,1,73和1.85nm^2/分子。

| Abstract: | The title complexes have been synthesized and characterized by UV, IR, low angle X-ray diffractometry, TG-DTA analysis and mole conductometric analysis. The surface pressure-area isotherm (π-A) behaviours of these complexes were investigated. The zero-pressure molecular area obtained for the complexes of La, Nd, Dy and Yb are 1.94, 1.93, 1.73 and 1.85nm^2 permolecule respectively, which is much larger than the value of 0.55nm^2 calculated according to structural data for Eu(TTA)~4^-. This indicates that the anion and cation of the complex may take a "shoulder" to "shoulder" arrangement on the substrate, and the angle between the alkyl chain and substrate may be very small. |
