Nevertheless, this method has been limited by the types and numbers of available on-surface transformations. While the majority of successful cases exploit thermally triggered dehalogenative carbon–carbon coupling and cyclodehydrogenation, rearrangement of appropriate functional moieties has received limited research attention. In a recent work, we describe the unprecedented interchain coupling and thermally induced skeleton rearrangement of (dihydro)indeno[2,1-b]fluorene (IF) polymers on an Au(111) surface under ultrahigh vacuum conditions, leading to different ladder polymers as well as fully fused graphene nanoribbon segments containing pentagonal and heptagonal rings. Au-coordinated nanoribbons are also observed. All structures are unambiguously characterized by high-resolution scanning probe microscopy. The results provide an avenue to fabricating a wider variety of π-conjugated polymers and carbon nanostructures comprising nonhexagonal rings as well as rarely explored organometallic nanoribbons. This record contains data of the calculations that support our results.</dc:description> <dc:identifier>https://archive.materialscloud.org/record/2024.8</dc:identifier> <dc:identifier>doi:10.24435/materialscloud:h2-x5</dc:identifier> <dc:identifier>mcid:2024.8</dc:identifier> <dc:identifier>oai:materialscloud.org:2046</dc:identifier> <dc:language>en</dc:language> <dc:publisher>Materials Cloud</dc:publisher> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode</dc:rights> <dc:subject>MARVEL/P4</dc:subject> <dc:subject>CSCS</dc:subject> <dc:subject>SNSF</dc:subject> <dc:subject>Indenofluorene</dc:subject> <dc:subject>STM</dc:subject> <dc:subject>Non-contact atomic force microscopy</dc:subject> <dc:subject>DFT</dc:subject> <dc:title>On-surface interchain coupling and skeletal rearrangement of indenofluorene polymers</dc:title> <dc:type>Dataset</dc:type> </oai_dc:dc>
