Interlocked Bis(polyrotaxane) of Cyclodextrin−Porphyrin Systems Mediated by Fullerenes

A nanometer-sized cyclodextrin−porphyrin−fullerene aggregate with an interlocked bis(polyrotaxane) structure is constructed from cyclodextrin−porphyrin conjugate and C60, exhibiting the significant chiral and electrochemical behaviors due to the presence of numerous porphyrin and fullerene units.
