## Description

- description: Graphene nanoribbons (GNRs) and nanographenes synthesized by on-surface
    reactions using tailor-made molecular precursors offer an ideal playground for
    a study of magnetism towards nano-spintronics. Although the zigzag edge of GNRs
    has been known to host magnetism, the underlying metal substrates usually veil
    the edge-induced Kondo effect. Here, we report the on-surface synthesis of unprecedented,
    π-extended 7-armchair GNRs using 7-bromo-12-(10-bromoanthracen-9-yl)tetraphene
    as the precursor. Characterization by scanning tunneling microscopy/spectroscopy
    revealed unique rearrangement reactions leading to pentagon- or pentagon/heptagon-incorporated,
    nonplanar zigzag termini, which demonstrated Kondo resonances even on bare Au(111).
    Density functional theory calculations indicate that the nonplanar structure significantly
    reduces the interaction between the zigzag terminus and the Au(111) surface, leading
    to a recovery of the spin localization of the zigzag edge. Such a distortion of
    planar GNR structures offers a degree of freedom to control the magnetism on metal
    substrates.
