【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一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1.85nm²/分子.更多还原

【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 (*******-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 1.85nm2 per molecule respectively, which is much larger than the value of 0.55nm2 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.更多还原
