Molecular design and exploitation of spin-polarized molecular wires based on macrocyclic aromatic amines

成功制备了基于多环芳香胺的新型分子线。这些分子线具有很强的给电子能力，而且当它们被氧化时，所产生的自旋在整个分子线上都是离域的。此外，在新制备的分子线中引入了氮氧化物自由基中心作为局域自旋源。总的来说，在分子线上产生的局域自旋和非局域自旋之间观察到明确的磁相互作用。

Novel molecular wires based on polycyclic aromatic amines were successfully prepared. These molecular wires exhibited strong electron-donating ability, and moreover, when they are oxidized, the generated spin was found to be delocalized over the whole molecular wire. In addition, nitroxide radical centers as a localized spin source were introduced into the newly prepared molecular wires. As a whole, the definite magnetic interaction was observed between the localized spins and the delocalized spin that was generated over molecular wire.
