摘　　要：研究了一种新型带有长烷基链的铕配合物Langmuir-Blodgett（LB）膜及其发光性质。实验结果表明，此种配合物能够在水面上形成稳定的单分子膜，单分子占有面积为0．6nm^2，并可将单分子Langmuir膜沉积在亲水的石英基片上，其紫外结果表明，位于287nm处的主吸收峰随着LB膜层数的增加而增加，其吸收强度随层数的增加呈线性关系，证明可以形成均匀LB膜。对其LB膜的荧光光谱研究结果显示，具有典型的铕配合物的发射峰，且具有一定的荧光强度。这为以铕配合物作为分子器件的材料研究提供了实验基础。A novel amphiphilic europium complex was synthesized and its LB films were also studied. Results showed that it could form stable monolayer on the surface of pure water subphase with a limiting area of 0.6nm^2 per molecule. Multilayer LB films could be transferred onto hydrophilic quartz substrate, which were characterized by ultraviolet in which showed that the absorbance of the LB films at 287nm scales linearly with number of layers deposited through the origin. Well Eu（Ⅲ） characteristic peaks can be observed in Emission spectroscopy . The researches can apply the basic knowledge for Eu complex in molecule device in future.
