The molecules arrange themselves in a complex, well-ordered long-range pattern, namely, a chiral hexagonal mesh of rings composed of six molecules. Submolecularly resolved STM images reveal the orientations of the molecular dipoles, which are confirmed by NC-AFM measurements. Density functional theory (DFT) calculations reproduce the STM images and their intriguing dependence on the junction bias and confirm that the experimental results allow us to fully determine the orientation of the functional units. Comparison with phenyl-TOTA reveals that the dipole\u2013dipole interaction of the pyridyl unit is strong enough to change the structure from a hexagonal close-packed pattern to a chiral hexagonal mesh of supramolecular hexagons. These results show that dipole functionalization may serve to control the formation of molecular assemblies on the surfaces.<\/jats:p>","DOI":"10.1021\/acs.jpclett.6c02295","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T20:18:42Z","timestamp":1788293922000},"page":"10388-10396","source":"Crossref","is-referenced-by-count":0,"title":["Dipole-Programmed\nChiral Porous Superlattice from\nTriangular Molecular Platforms on Ag(111)"],"prefix":"10.1021","volume":"17","author":[{"given":"Behzad","family":"Mortezapour","sequence":"first","affiliation":[{"name":"Christian-Albrechts-Universita\u0308t zu Kiel , , ,","place":["Kiel, Germany, 24098"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastian","family":"Hamer","sequence":"additional","affiliation":[{"name":"Christian-Albrechts-Universita\u0308t zu Kiel , , ,","place":["Kiel, Germany, 24098"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6396-6991","authenticated-orcid":true,"given":"Rainer","family":"Herges","sequence":"additional","affiliation":[{"name":"Christian-Albrechts-Universita\u0308t zu Kiel , , ,","place":["Kiel, Germany, 24098"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyeji","family":"Choi","sequence":"additional","affiliation":[{"name":"Fritz-Haber Institute of the Max-Planck Society , , Faradayweg 4-6 , ,","place":["Berlin, Germany, 14195"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7226-9592","authenticated-orcid":true,"given":"Martin","family":"Wolf","sequence":"additional","affiliation":[{"name":"Fritz-Haber Institute of the Max-Planck Society , , Faradayweg 4-6 , ,","place":["Berlin, Germany, 14195"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8059-3752","authenticated-orcid":true,"given":"Akitoshi","family":"Shiotari","sequence":"additional","affiliation":[{"name":"Fritz-Haber Institute of the Max-Planck Society , , Faradayweg 4-6 , ,","place":["Berlin, Germany, 14195"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7808-0395","authenticated-orcid":true,"given":"Roberto","family":"Robles","sequence":"additional","affiliation":[{"name":"Centro de Fi\u0301sica de Materiales CFM\/MPC (CSIC-UPV\/EHU) , ,","place":["Donostia-San Sebastia\u0301n, Spain, 20018"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola\u0301s","family":"Lorente","sequence":"additional","affiliation":[{"name":"Centro de Fi\u0301sica de Materiales CFM\/MPC (CSIC-UPV\/EHU) , ,","place":["Donostia-San Sebastia\u0301n, Spain, 20018"]},{"name":"Donostia International Physics Center (DIPC) , ,","place":["Donostia-San Sebastia\u0301n, Spain, 20018"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1165-9065","authenticated-orcid":true,"given":"Richard","family":"Berndt","sequence":"additional","affiliation":[{"name":"Christian-Albrechts-Universita\u0308t zu Kiel , , ,","place":["Kiel, Germany, 24098"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,27]]},"reference":[{"key":"2026091008103310100_cit1","doi-asserted-by":"publisher","first-page":"5148","DOI":"10.1002\/adma.201102022","article-title":"Molecular\nSelf-Assembly at Solid Surfaces","volume":"23","author":"Otero","year":"2011","journal-title":"Adv.
