摘　　要：将三聚氰胺添加到3,3’,4,4’-联苯邻二甲酰亚胺(化合物1)的自组装体系中,实现了自组装结构从片状到块状的转变.通过场发射扫描电子显微镜、红外光谱、紫外吸收光谱、荧光光谱和X射线衍射等实验对自组装结构和形成机理进行了研究.化合物1的紫外可见吸收和发射光谱的强度随着三聚氰胺的添加逐渐减弱.化合物1分子间的氢键发生变化,同时在化合物1和三聚氰胺之间形成新的氢键.氢键在调控自组装过程中起着重要角色.The structure evolution from sheet to cube of the self-assembly was observed in two component system containing 1 and melamine. The self-assembly structure and the formation mechanism had been studied and certified by field emission scanning electron microscopy,IR,UV-vis,fluorescence and X-ray diffraction experiment data. The UVvis absorption and emission spectra of the compound 1 solution decreased with the addition of melamine. The intermolecular H-bonding formed by compound 1 was changed into that formed by compound 1 and melamine. The H-bonding played the key role in regulating the self-assembly process.
