新合成了一种新型两亲性铕(III)配合物，三(α-噻吩酰基三氟丙酮)单(1-十八烷基-2-(2-吡啶基)苯并咪唑)铕(III)(Eu(TTA)(3)(L18))。它在纯水面相上形成稳定的单层膜，每个分子的极限面积为0.52 nm(2)。多层 Langmuir-Blodgett (LB) 薄膜构建在亲水性石英基板上，并通过紫外光谱和发射光谱以及低角度 X 射线衍射分析进行表征。 LB薄膜的高度有序结构通过五个尖锐的布拉格衍射峰的出现揭示出来，其中最强的一个的半宽度仅为0.16埃。 (C) 2003 Elsevier Science B.V. 保留所有权利。
A novel amphiphilic europium(III) complex, tris(alpha-thenoyltrifluoroacetonato)mono(1-octadecyl-2-(2-pyridyl)benzimidazole) europium(III) (Eu(TTA)(3)(L18)), was newly synthesized. It formed stable monolayer film on pure water subphase with a limiting area of 0.52 nm(2) per molecule. Multilayer Langmuir-Blodgett (LB) film was built onto hydrophilic quartz substrate and characterized by ultraviolet and emission spectroscopy, and low-angle x-ray diffraction analyses. Quite highly ordered structure of the LB film was revealed by the appearance of five sharp Bragg diffraction peaks with half-width at full maximum for the strongest one being only 0.16 Angstrom.
