Toward metallic molecular wires!

Toward metallic molecular wires!
Graphene nanoribbons (GNRs) with a width < 10 nm have promising applications in the future nano-electronics. While semi-conducting GNRs can be applied as active components in field effect transistors, the metallic GNRs can be used as conducting wires. So far, the synthesis of GNRs with potential metallic properties is still not successful. In a recent publication in Link, A/P Wu Jishan’s group reported the challenging synthesis and physical characterizations of a series of soluble and stable rylene ribbon molecules with the record length, which can serve as good model compounds of the narrowest armchair graphene nanoribbon. They observed very unusual open-shell diradical character for long rylene molecules, which can be correlated to the potential metallic property of the infinite polyrylene ribbon. This work was selected as a cover in the January issue.
