Chemistry at the Nanoscale: Synthesis of an N@C60–N@C60Endohedral Fullerene Dimer

Rattling the cage: The rapid one‐pot double 1,3‐dipolar cycloaddition reaction of the rare endohedral fullerene N@C60to an oligo(p‐phenylene polyethylene) bis(aldehyde) using a novel amino acid derivative as an anchoring group is reported. The method provides the first example of a chemically linked, two‐spin‐center N@C60–N@C60molecule (see picture). Assessment of this platform as an element of a quantum computing register is attractive.
