two compounds can gelate a variety of organic solvents and form interesting morphologies. Transmission and scanning electron microscopy of the xerogels of the two compounds showed vesicle and solid sphere morphologies, respectively, even though their molecular structures are very close. The mechanism of the self-assembly process was investigated by 1H NMR, IR, 2D-NOESY spectra, wide-angle X-ray diffraction
两个相似 萘二甲酰亚胺合成了有机基胶凝剂。这两种化合物可以使多种有机溶剂胶凝并形成有趣的形态。两种化合物的干凝胶的透射电子显微镜和扫描电子显微镜分别显示了囊泡和固体球的形态,即使它们的分子结构非常接近。自组装过程的机理由1研究1 H NMR,IR,2D-NOESY光谱,广角X射线衍射和流变实验。研究表明,多种分子内/分子间相互作用的相互作用和竞争是这些化合物自组装成囊泡和固体球体的主要决定因素。很少会遇到能够确定非典型两亲系统中囊泡形成的单个功能基团。因此,这些结果为形态控制,特别是非典型两亲系统中囊泡的形成提供了进一步的见解。
