Müllen, Klaus Fasel, Roman Narita, Akimitsu 2024-01-09 On-surface synthesis serves as a powerful approach to construct π-conjugated carbon nanostructures that are not accessible by conventional wet chemistry. 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. application/octet-stream text/markdown https://doi.org/10.24435/materialscloud:h2-x5 oai:materialscloud.org:2046 mcid:2024.8 eng Materials Cloud https://doi.org/10.1002/macp.202300345 https://renkulab.io/projects/new?data=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 https://archive.materialscloud.org/communities/mcarchive https://doi.org/10.24435/materialscloud:jh-p0 info:eu-repo/semantics/openAccess Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/legalcode MARVEL/P4 CSCS SNSF Indenofluorene STM Non-contact atomic force microscopy DFT On-surface interchain coupling and skeletal rearrangement of indenofluorene polymers info:eu-repo/semantics/other
