It was clarified that a variety of fluoroalkyl end-capped oligomers can form the self-assembled molecular aggregates with nm levels in aqueous and organic media. In fact, the dynamic light scattering measurements showed that the size of molecular assemblies formed in aqueous solution of fluorinated oligomer and that in aqueous solution of fullerene solubilized by this oligomer are 22nm and 113nm levels, respectively. The increase of the size of the molecular assemblies formed by the solubilization of fullerene into water indicates the interaction of self-assemblies of fluorinated oligomer with fullerene as a guest molecule to form the host-guest intermolecular complex. In addition, fluorinated oligomers were found to be a convenient tool for the arrangements of fullerenes above the poly(methyl methacrylate) [PMMA] surface, and the higher fluorescent intensity of fullerene was obtained in the modified PMMA surface, although the reverse side of this modified film surface afforded an extremely weak fluorescent intensity. Self-assembled fluorinated molecular aggregates were also effective for solubilizing carbon nanotube not only in water but also in common organic solvents such as toluene, xylene and chloroform. Therefore, these findings would open a new route to the applications to biological fields and surface modifications in material sciences.

可以澄清的是，各种氟烷基终端的低聚物可以在水性和有机培养基中具有NM水平的自组装分子聚集体。实际上，动态光散射测量结果表明，在氟化寡聚物水溶液中形成的分子组件的大小，并且在该低聚物溶解的富勒烯水溶液中分别为22nm和113nm水平。富勒烯溶解在水中形成的分子组件大小的增加表明氟化寡聚物的自组合与富勒烯的自组合相互作用，作为宾客分子，形成了宿主 - 巨球间分子络合物。此外，发现氟化寡聚是在聚（甲基丙烯酸甲酯）[PMMA]表面排列富勒烯的方便工具，尽管在改良的PMMA表面中获得了较高的富勒烯荧光强度，尽管这种修饰的膜表面的相反侧为荧光强度提供了极低的荧光强度。自组装的氟化分子聚集体也有效地溶解碳纳米管不仅在水中，而且在常见的有机溶剂中，例如甲苯，二甲苯和氯仿。因此，这些发现将为材料科学中的生物领域和表面修饰的应用打开新的途径。
