A series of tailor‐made paramagnetic bis‐fullerene derivatives capable of bridging two adjacent graphene (G) sheets for performing magnetic single‐molecule junctions (SMJs) have been developed. Specifically, magnetic molecular wires consisting of two highly π‐conjugated (phenylethynyl, bis‐phenylethynyl or naphthylethynyl) linker moieties coordinated to Fe II and Co II spin‐crossover (SC) complexes in an octahedral environment and endowed with fullerene (C 60 ) end‐groups have been synthesized. The use of C 60 units as anchoring groups improves the contact between the G electrodes in comparison with conventional Au‐selective groups. This novel synthetic pathway provides access to a completely new family of SC compounds suitable for the development of SMJs using graphene nanoelectrodes.
