Efficient chirality transfer affords well-defined all-pS or all-pR planar chirality, with the corresponding chiroptical responses remaining essentially unchanged over the investigated temperature range. Remarkably, macrocyclization of racemic precursors undergoes spontaneous chiral self-sorting to preferentially afford homochiral macrocycles. This strategy provides a new approach to the generation and stabilization of planar chirality in pillararenes.<\/jats:p>","DOI":"10.1021\/acs.orglett.6c03319","type":"journal-article","created":{"date-parts":[[2026,9,3]],"date-time":"2026-09-03T08:43:38Z","timestamp":1788425018000},"page":"11322-11327","source":"Crossref","is-referenced-by-count":0,"title":["Chiral Bis-Urea\nEmbedded Pillararenes with Self-Sorted\nPlanar Chirality"],"prefix":"10.1021","volume":"28","author":[{"given":"Kai","family":"Diao","sequence":"first","affiliation":[{"name":"Nanjing University , , ,","place":["Nanjing, China, 210023"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yun","family":"Lu","sequence":"additional","affiliation":[{"name":"Nanjing University , , ,","place":["Nanjing, China, 210023"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyue","family":"Wen","sequence":"additional","affiliation":[{"name":"Nanjing University , , ,","place":["Nanjing, China, 210023"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qing","family":"Liu","sequence":"additional","affiliation":[{"name":"Changzhou University , , ,","place":["Changzhou, China, 213164"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2864-9587","authenticated-orcid":true,"given":"Tangxin","family":"Xiao","sequence":"additional","affiliation":[{"name":"Changzhou University , , ,","place":["Changzhou, China, 213164"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhouyu","family":"Wang","sequence":"additional","affiliation":[{"name":"Xihua University , , ,","place":["Chengdu, China, 610039"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5775-3714","authenticated-orcid":true,"given":"Leyong","family":"Wang","sequence":"additional","affiliation":[{"name":"Nanjing University , , ,","place":["Nanjing, China, 210023"]},{"name":"Xihua University , , ,","place":["Chengdu, China, 610039"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,1]]},"reference":[{"key":"2026091110072043200_cit1a","doi-asserted-by":"publisher","first-page":"7017","DOI":"10.1021\/ja01002a035","article-title":"Cyclic polyethers and their complexes with metal salts","volume":"89","author":"Pedersen","year":"1967","journal-title":"J.
