文摘

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 (C₆₀) end-groups have been synthesized. The use of C₆₀ 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.
