两亲性分子在液 /固界面组装成二维有序的结构是目前超分子科学研究的热点。含有偶氮苯单链季铵盐化合物 4-[(4’ -十二烷氧基 )偶氮苯氧基 ]己基三乙基溴化铵 (简写为C12 AzoC6 N+)在水溶液中能聚集成胶束 ,当它自组织到新鲜的云母片上时 ,则形成二维有序的纳米尺寸的树枝状条带结构。为了进一步系统的研究该自组织树枝状条带结构单层膜的性质 ,本文利用扫描力显微镜 (SFM)研究了该化合物在大于其临界胶束浓度时在新鲜的云母片上自组织成树枝状条带结构的行为 ,并通过共聚焦拉曼光谱对该自组织树枝状条带结构单层膜进行了测试 ,指认了固体和自组织单层膜的拉曼位移。通过比较 ,我们进一步确认了在云母片上的自组织的二维有序的纳米尺寸树枝状条带单层膜的结构。这将为这种二维有序的纳米尺寸树枝状条带结构将来的应用奠定基础。
Amphiphilic molecules in the liquid / solid interface assembled into two-dimensional ordered structure is currently the focus of supramolecular science. 4 - [(4’-dodecyloxy) azo phenoxy] hexyltriethylammonium bromide (abbreviated as C12 AzoC6 N +) containing azobenzene single chain quaternary ammonium salt compound can be aggregated in aqueous solution The beam, when it self-organizes onto fresh mica, forms a two-dimensional ordered, nanosized dendritic band structure. In order to further study systematically the nature of the self-organized dendritic single-layered film, we investigated the self-organized dendrites on fresh mica flakes by scanning force microscopy (SFM) Band structure of the self-organized dendritic tape monolayer film was tested by confocal Raman spectroscopy, to identify the solid and self-organized monolayer film Raman shift. By comparison, we further confirmed the structure of self-organized, two-dimensionally ordered nanosized dendritic monolayer films on mica. This will lay the foundation for the future application of this two-dimensional ordered nanosized dendritic tape structure.
