氢键在双组分自组装体系中的调控效应

H-bonding Regulation Effect of Two Component Self-assembly System

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．

Abstract: 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 UV-vis 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
