Here, we investigate the self\u2010assembly of racemic 2,3\u2010dicarbonitrile tetrahelicene on Ag(111). Using low\u2010temperature scanning tunneling microscopy in combination with density functional theory calculations, we resolve the evolution of molecular organization as a function of coverage. After room\u2010temperature deposition at submonolayer coverage, the tetrahelicene moiety spontaneously resolves into extended homochiral Kagom\u00e9 domains upon cooling. The resulting monolayer consists of hexameric dimer motifs arranged in a porous network. These mirror\u2010related supramolecular enantiomorphs are characteristic of two\u2010dimensional conglomerate crystallization. As the surface coverage increases, the system undergoes a transition toward denser packing. At saturation, compact domains form that retains long\u2010range lattice order while exhibiting a regular yet enantiomerically unbalanced distribution of both handednesses. The nonrandom incorporation of enantiomers distinguishes this phase from a racemic solid solution and instead indicates a compositionally biased, structurally ordered mixed phase.<\/jats:p>","DOI":"10.1002\/chir.70106","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T03:05:47Z","timestamp":1777518347000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface\u2010Confined Tetrahelicene Monolayers"],"prefix":"10.1002","volume":"38","author":[{"given":"Aleksandra","family":"Cebrat","sequence":"first","affiliation":[{"name":"Empa Swiss Federal Laboratories for Materials Science and Technology  D\u00fcbendorf Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Martin","sequence":"additional","affiliation":[{"name":"Univ Angers, CNRS MOLTECH\u2010Anjou, SFR MATRIX  Angers France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pingo","family":"Mutombo","sequence":"additional","affiliation":[{"name":"Nanosurf Lab Institute of Physics of the Czech Academy of Sciences  Prague Czech Republic"},{"name":"Department of Refining and Petrochemistry, Faculty of Oil, Gas and Renewable Energies University of Kinshasa  Kinshasa Democratic Republic of the Congo"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Manfred","family":"Parschau","sequence":"additional","affiliation":[{"name":"Empa Swiss Federal Laboratories for Materials Science and Technology  D\u00fcbendorf Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9970-4494","authenticated-orcid":false,"given":"Narcis","family":"Avarvari","sequence":"additional","affiliation":[{"name":"Univ Angers, CNRS MOLTECH\u2010Anjou, SFR MATRIX  Angers France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2077-4922","authenticated-orcid":false,"given":"Karl\u2010Heinz","family":"Ernst","sequence":"additional","affiliation":[{"name":"Empa Swiss Federal Laboratories for Materials Science and Technology  D\u00fcbendorf Switzerland"},{"name":"Nanosurf Lab Institute of Physics of the Czech Academy of Sciences  Prague Czech Republic"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,29]]},"reference":[{"key":"e_1_2_8_2_1","volume-title":"Right Hand, Left Hand: The Origins of Asymmetry in Brains, Bodies, Atoms and Cultures","author":"McManus C.","year":"2002"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/9783906390598"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201104477"},{"key":"e_1_2_8_5_1","volume-title":"Chemical Structure, Spatial Arrangement: The Early History of Stereochemistry, 1874\u20131914","author":"Ramberg P.
