设计了一系列新型的具有对称芳香核和不同取代基的三方Schiff碱两亲物，并研究了它们的界面组装。当在金属离子亚相中时，所有化合物都可以发生原位配位。配位膜可以转移到固体基底上，随后通过各种光谱方法如UV-vis和傅立叶红外光谱以及原子力显微镜测量的形态表征来表征。此外，在不同pH值的酸性或碱性亚相中，由于碱性亚相中酚基的解离和强酸性亚相中甲亚胺的质子化，界面行为和形貌发生了明显的变化。根据分子的三角形结构和不同的取代基，这些两亲分子在有序分子膜中表现出不同的组装行为。同时，对分子结构和头基对组装行为的影响提出了合理的解释。
A new series of trigonal Schiff base amphiphiles with symmetric aromatic cores and different substituted headgroups were designed and their interfacial assemblies were investigated. When on the metal ions subphases, an in situ coordination can occur for all compounds. The coordinated films could be transferred onto solid substrates and subsequently characterized by various spectroscopic methods such as UV–vis and Fourier infrared spectra as well as the morphological characterization with atomic force microscopy measurement. In addition, on acidic or alkaline subphases with different pH values, the interfacial behaviors and morphologies changed obviously due to the dissociation of the phenol group at alkaline subphase and protonation of the azomethine at strong acidic subphase. Depending on the trigonal molecular structures and different substituted headgroups, these amphiphiles showed distinct assembly behaviors in the organized molecular films. At the same time, a rational explanation about the influence of molecular structures and headgroups on regulating the assembly behaviors was proposed.
