About this collection
This issue shows the impact of coordination chemistry in the emerging field of Molecular Spintronics, covering the three different facets of the field: the use of molecules in the development of a new generation of spintronic devices; the miniaturization of the device to reach the single-molecule limit (molecular nanospintronics); and the search for molecular spin qubits of interest in quantum computing.
