This synthetic approach forms nanoribbons with well-defined widths and atomically precise edges, which are necessary for ensuring bandgap uniformity. However, neither on-surface nor solution-based GNR synthesis techniques adequately address the problem of positional control, which is crucial to the fabrication of GNR transistors. To better understand this issue, we investigate the on-surface ordering of 10, 10\u2032-dibromo-9, 9\u2032-bianthracene (DBBA), the 7A-GNR monomer precursor. Scanning tunneling microscopy imaging shows that DBBA molecules spontaneously assemble on Au(111) into non-covalent two-dimensional islands. By varying sample temperature during and after deposition, we observe three different adsorbate arrangements. These two-dimensional packing structures demonstrate differing responses to localized excitations. The difference in packing structures and their respective responses to electro-mechanical perturbations can give us insight into how to best optimize conditions for locally controlled and large-scale thermal GNR polymer growth.<\/jats:p>","DOI":"10.1088\/1361-6528\/ae0044","type":"journal-article","created":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T22:47:47Z","timestamp":1756421267000},"page":"375601","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Top-down reorganization of self-assembled monolayers on Au(111)"],"prefix":"10.1088","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-2439-3708","authenticated-orcid":true,"given":"Steven","family":"Kolaczkowski","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7295-1775","authenticated-orcid":false,"given":"Gregory S","family":"Girolami","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7285-4310","authenticated-orcid":false,"given":"Joseph W","family":"Lyding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2025,9,10]]},"reference":[{"key":"nanoae0044bib1","doi-asserted-by":"publisher","first-page":"531","DOI":"10.1109\/LED.2010.2045100","type":"journal-article","article-title":"Scalability of atomic-thin-body (ATB) transistors based on graphene nanoribbons","volume":"31","author":"Zhang","year":"2010","journal-title":"IEEE Electron Device Lett."},{"key":"nanoae0044bib2","doi-asserted-by":"publisher","DOI":"10.1063\/1.3682319","type":"journal-article","article-title":"Metal contact to graphene nanoribbon","volume":"100","author":"Seol","year":"2012","journal-title":"Appl.
