Synthesis of pentadecaphenylenes, their inclusion properties, and nanostructure formation with C60

Synthesis of macrocyclic pentadecaphenylene was carried out via electron-transfer oxidation of the corresponding Lipshutz cuprate. Pentadecaphenylene self-aggregated in solution to form a gel. Furthermore, it incorporated C60 in its cavity to produce a fibrous inclusion complex which showed a high gelation ability in benzene.
