Synthesis of mol. containers capable of incorporating multiple fullerenes remains challenging. Reported here is that room-temperature mixing of metal ions with W-shaped bispyridine ligands featuring polyaromatic panels results in the quant. formation of a peanut-shaped M2L4 capsule. The capsule reversibly converts into two mols. of an ML2 double tube in response to changes in the solvent. Notably, the capsule allows the incorporation of two fullerene mols. into the connected two spherical cavities at room temperature The close proximity yet non-contact of the encapsulated C60 mols., with a separation of 6.4 Å, was revealed by x-ray crystallog. anal. The resultant, unusual fullerene dimer undergoes sequential reduction within the capsule to generate (C60.-)2, C60.-·C602-, and (C602-)2 species. Furthermore, temperature-controlled stepwise incorporation of two C60 mols. into the capsule is demonstrated.
