Room‐Temperature Spin‐Dependent Transport in Metalloporphyrin‐Based Supramolecular Wires

Here we present room-temperature spin-dependent charge transport measurements in single-molecule junctions made of metalloporphyrin-based supramolecular assemblies. They display large conductance switching for magnetoresistance a junction. The depends acutely on the probed electron pathway through wire: those involving metal center showed marked effects as opposed to exclusively porphyrin ring which nearly complete absence transport. molecular junction is highly anisotropic, being observable when magnetization ferromagnetic electrode oriented along main axis, and almost suppressed it perpendicular. key ingredients above effect manifest are electronic structure paramagnetic metalloporphyrin, spinterface created at molecule–electrode contact.
