To this end, III\u2013VI\u2013VII solids have emerged as a distinct class of ternary 1D van der Waals (vdW) crystals which bear atomically precise helical motifs. However, the physical understanding of the intrinsic and size\u2010dependent properties of these materials is limited by the lack of synthetic strategies to directly access freestanding nanocrystals in high volumes. Using GaSI as a representative phase, a bottom\u2010up strategy is presented to grow high yields of ultrathin nanostructures based on this helical materials class. With this strategy, it is possible to grow single crystals of 1D nanowires with thicknesses in the 10\u2013100\u00a0nm range at high temperature conditions, as well as quasi\u20102D nanoribbons at lower temperatures. The bandgap of the nanowires is established in the UV region and demonstrates the persistence of nonlinear optical behavior as evidence of the persistence of the noncentrosymmetric crystal structure of GaSI at the nanoscale. Inspired by these results, the effect of the helical nature of GaSI on the electronic structure of hypothetical single chains is probed from first principles and shows the pronounced handedness\u2010dependent and helicity\u2010imposed spin polarization at the single helix regime.<\/jats:p>","DOI":"10.1002\/adma.202510230","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T12:46:22Z","timestamp":1764852382000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Dimensionally Resolved Nanostructures of an Atomically Precise and Optically Active 1D van der Waals Helix"],"prefix":"10.1002","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9574-0903","authenticated-orcid":false,"given":"Kaitlyn G.","family":"Dold","sequence":"first","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joni","family":"Spencer","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Griffin M.","family":"Milligan","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sirisak","family":"Singsen","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhe","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy University of California  Irvine CA 92697\u20104575 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus","family":"Marracci","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitri Leo Mesoza","family":"Cordova","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thanh N.","family":"Huynh","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaleolani","family":"Ogura","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshihiro","family":"Aoki","sequence":"additional","affiliation":[{"name":"Irvine Materials Research Institute University of California Irvine  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xingxu","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitry A.","family":"Fishman","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of California  Irvine CA 92697 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoqing","family":"Pan","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering University of California  Irvine CA 92697 USA"},{"name":"Department of Physics and Astronomy University of California  Irvine CA 92697\u20104575 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruqian","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Physics and Astronomy University of California  Irvine CA 92697\u20104575 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9143-3140","authenticated-orcid":false,"given":"Elizabeth M.
