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.

阐明了各种氟烷基端盖低聚物在水介质和有机介质中可形成纳米级自组装分子聚集体。事实上，动态光散射测量表明，在含氟低聚物水溶液中形成的分子组装体的大小和在该低聚物溶解的富勒烯水溶液中形成的分子组装体的大小分别为22nm和113nm。富勒烯在水中溶解形成的分子组合尺寸的增加表明，氟化低聚物的自组装与作为客体分子的富勒烯相互作用，形成了主-客体分子间复合物。此外，氟化低聚物被发现是在聚甲基丙烯酸甲酯[PMMA]表面上排列富勒烯的方便工具，并且在改性的PMMA表面上获得了更高的富勒烯荧光强度，尽管这种改性膜表面的反面荧光强度非常弱。自组装的氟化分子聚集体不仅在水中，而且在常见的有机溶剂（如甲苯、二甲苯和氯仿）中也能有效地增溶碳纳米管。因此，这些发现将为生物领域和材料科学表面修饰的应用开辟一条新的途径。
