metal–organic tetrahedron forms host–guest
complexes containing 1–4 equiv of fullerene C60,
depending on the solvent employed. The molecules of C60 were bound anticooperatively within well-defined pockets; an X-ray
crystal structure of three fullerenes inside the tetrahedron was obtained.
Electrochemical measurements revealed that the electron-accepting
properties of the fullerenes inside the capsules were altered depending
on the mode of encapsulation. The binding of multiple fullerenes was
observed to increase the electron affinity of the overall cluster,
providing a noncovalent method of tuning fullerene electronics.
