中文摘要:

硅石 nanococoons 与卷或在墙中的同心圆形的毛孔隧道最近吸引了许多注意。然而,他们的形成很好没被说明。此处,空硅石与组织毛孔隧道平行轰炸到壳表面用 chiral low-molecular-weight amphiphile 的 self-assemblies 通过一个单个模板的方法被准备, L-18Phe6PyBr,在 dilute 集中下面的模板。这些 nanococoons 用 X 光检查衍射计和 N2 吸着被描绘。他们的形成清楚地在在低电压被拿的地排放电子显微镜学图象被显示出。而且,像的传播电子显微镜学图象不同反应时间显示了合作自我装配的机制。nanocoons 从卷的 nanoribbons 被形成,这也被发现。

英文摘要:

Silica nanococoons with coiled or concentric circular pore channels in the walls attracted much attention, recently. However, the formation of them is not well illustrated. Herein, hollow silica shells with organized pore channels parallel to the shell surface were prepared through a single-templating method using the self-assemblies of a chiral low-molecular-weight amphiphile, L-18Phe6PyBr, as templates under a dilute concentration. These nano- cocoons were characterized using X-ray diffractometer and N2 sorption. The formation of them was clearly shown in the field-emission electron microscopy images which were taken at a low voltage. Moreover, transmission elec- tron microscopy images taken after different reaction times indicated a cooperative self-assemble mechanism. It was also found that the nanocoons were formed from coiled nanoribbons.
