Shake, rattle, and roll : As a guest within a short‐spaced cyclic dimer of an organorhodium porphyrin 1 , fullerenes such as C 60 and C 70 start to oscillate by slipping through the host cavity. This dynamic motion is substantially prohibited by another molecule of 1 through the formation of capsule‐type inclusion complexes. In contrast, a larger fullerene such as C 76 can hardly slip through the host cavity but is simply encapsulated by two molecules of 1 .
