英文摘要: The stacking interactions between F center dot center dot center dot H-N hydrogen-bonded foldamers 1-3, bis-foldamer 4, and trisfoldamer 5 and C-60 and C-70 are described. Compound 4 contains two folded units, which are connected by an isophthalamide linker, whereas 5 has a C-3-symmetrical discotic structure, in which three folded units are connected by a benzene-1,3,5-tricarboxamide unit. UV/Vis, fluorescence, and NMR experiments have revealed that the foldamers or folded units strongly stack with fullerenes in chloroform. ne (apparent) association constants of the respective complexes have been determined by a fluorescence titration method. The strong association is tentatively attributed to intermolecular cooperative fluorophertyl center dot center dot center dot pi and solvophobic interactions. A similar but weaker interaction has also been observed between an Me center dot center dot center dot OH-N hydrogen-bonded foldamer and fullerenes. AFM studies have revealed that the surfaces of 3 and 4 show fibrous networks, while the surface of 5 shows particles. In sharp contrast, mixtures of 3 and 4 with C-60 have been shown to generate thinner separated fibrils, whereas a mixture of 5 and C-60 produces honeycomb-like nano networks, for which a columnar cooperative stacking pattern is proposed. The results demonstrate the usefulness of F center dot center dot center dot H-N hydrogen-bonded folded structures in the construction of nanoscaled materials.
