中文摘要：
研究了芳香席夫碱的设计合成、界面相行为以及与铜离子的配位过程,并与离位合成的铜复合物的界面组装行为进行了对比.利用表面压-面积等温线、紫外光谱、红外光谱、原子力显微镜等一系列实验方法来详细表征组装膜.结果表明,席夫碱配体与铜复合物均可在气液界面上形成稳定的有序组装膜,并可以转移到固体基片上构筑多层膜.进而,席夫碱配体在纯水界面上表现出奇特的相变.在相变点前后,二维的平膜变化成了三维的纤维状组装结构.然而,对于铜离子亚相上的组装过程却没有出现较大的变化.两者之间明显的差异可归因于在气液界面超分子组装过程中的分子构型以及疏水性能的不同引起的.目前的工作为制备和调控有序组装膜提供了有益探索.
英文摘要：
A novel aromatic Schiff base ligand has been designed and its interfacial phase behavior as well as its in situ coordination with Cu（ll） ions on the surface of pure water was compared with those of the corresponding pre-synthesized Cu（ll） complex. Surface pressure-area isotherms, ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, and atomic force microscopy were used to characterize deposited monolayer and multilayer films of the complexes. Both the ligand and corresponding complex formed stable monolayer or multilayer films at the air/water interface, which could be subsequently transferred onto solid substrates to construct Langmuir-Blodgett films. A novel phase transition was observed when the ligand was spread on the surface of pure water. During this phase transition, the two-dimensional （2D） flat film changed into three-dimensional （3D） fiber-like nanoarchitectures. However, upon coordination with Cu（ll） ions, only flat films were obtained. This phenomenon was thought to be caused by the change of molecular conformation and/or hydrophobicity
