Summary

Magnetic metal complexes have been proposed as Quantum Bits (Qubits) candidates units for Quantum Computing (QC) and Quantum Information Processing (QIP). Herein, we report on the implementation of metal complexes into nanometre-sized (single-) molecular spintronic devices by a combination of bottom-up self-assembly and top-down lithography techniques. The controlled generation of magnetic molecular nanostructures on conducting surfaces and electrodes will be shown, self-assembled on sp2-carbon nano-structures (SW-CNTs, graphene, etc.), or inside nano-gap gold junctions. The quantum properties of the metal complexes inside of the obtained supramolecular Quantum Devices (SMQD) are addressed at the single molecule level in view of their I-V-characteristics by means of UHV- and solution-based scanning probe and electromigration techniques.1-10
