## Title

    reactions on Au(111)

## Description

- description: Skeletal rearrangement reaction is a class of important chemical reactions
    to synthesize various constitutional isomers from a given precursor molecule.
    This approach allows the synthesis of diverse nanographenes incorporating five-
    and seven-membered rings, thereby tuning their chemical and physical properties.
    Here, we present formation of five types of closed-shell and two types of open-shell
    nanographenes on Au(111) via carbon rearrangements of 7-(2,6-dimethylphenyl)-12-[10-(2,6-dimethylphenyl)anthracen-9-yl]tetraphene.
    The structural, electronic, and magnetic properties of various products composed
    of pentagonal or pentagonal/heptagonal rings were in-detail investigated with
    a combination of bond-resolved scanning tunneling microscopy/scanning tunneling
    spectroscopy at 4.3 K and density functional theory calculations. We found that
    both zigzag edges and fused pentagonal rings significantly affect the band gap
    and the spin polarization. This discovery could facilitate the on-surface synthesis
    of intriguing carbon nanostructures through skeletal rearrangement.
