20.500.12556/DKUM-92381 Periodic arrays of chiral domains generated from the self-assembly of micropatterned achiral lyotropic chromonic liquid crystal Achiral building blocks forming achiral structures is a common occurrence in nature, while chirality emerging spontaneously from an achiral system is usually associated with important scientific phenomena. We report on the spontaneous chiral symmetry-breaking phenomena upon the topographic confinement of achiral lyotropic chromonic liquid crystals in periodically arranged micrometer scale air pillars. The anisotropic fluid arranges into chiral domains that depend on the arrangement and spacing of the pillars. We characterize the resulting domains by polarized optical microscopy, support their reconstruction by numerical calculations, and extend the findings with experiments, which include chiral dopants. Well-controlled and addressed chiral structures will be useful in potential applications like programmable scaffolds for living liquid crystals and as sensors for detecting chirality at the molecular level. physical chemistry atmospheric chemistry chromatography deformation silicon symmetry breaking chiral domains liquid crystal fizikalna kemija atmosferska kemija kromatografija deformacija silicij razbijanje simetrije kiralne domene tekoči kristali true false true ACS Publications Angleški jezik Slovenski jezik Znanstveno delo 2025-04-03 12:11:16 2025-04-03 12:35:03 2025-04-04 03:13:11 0000-00-00 00:00:00 2020 0 0 Str. 1964-1970 št. 11 Letn. 6 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-07-28 0000-00-00 2020-09-09 544 28153859 10.1021/acscentsci.0c00995 2374-7951 Park-2020-Periodic_Arrays_of_Chiral_Domains_Ge.pdf Park-2020-Periodic_Arrays_of_Chiral_Domains_Ge.pdf 1 AE074BF857EE2E57D9B0A79BD2948552 fe34432239d58f252d6231aae9b0e0c60a992f3eddebdb72bd364dd8aa73fe65 bd3c4513-1076-11f0-a266-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189960 https://doi.org/10.1021/acscentsci.0c00995 0 f021f609-1076-11f0-a266-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=189961 Fakulteta za naravoslovje in matematiko 0 0 0
