20.500.12556/DKUM-90945 Photonic bandgap in achiral liquid crystals - a twist on a twist Achiral mesogenic molecules are shown to be able to spontaneously assemble into liquid crystalline smectic phases having either simple or double-helical structures. At the transition between these phases, the double-helical structure unwinds. As a consequence, in some temperature range, the pitch of the helix becomes comparable to the wavelength of visible light and the selective reflection of light in the visible range is observed. The photonic bandgap phenomenon is reported for achiral liquid crystals. chirality helical structures liquid crystals photonic bandgap twist–bend phases kiralnost spiralne strukture tekoči kristali fotonska vrzel true false true Wiley Angleški jezik Slovenski jezik Znanstveno delo 2024-10-10 10:58:03 2024-10-10 11:19:20 2024-10-11 03:15:53 0000-00-00 00:00:00 2021 0 0 Str. 1-7 Št. 39, št. članka 2103288 Letn. 33 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-04-29 2021-06-22 2021-08-16 548/549 80061955 10.1002/adma.202103288 1521-4095 Pociecha-2021-Photonic_Bandgap_in_Achiral_Liqu.pdf Pociecha-2021-Photonic_Bandgap_in_Achiral_Liqu.pdf 1 3FA403E1828512A7F23B0FDB07397391 e13f3b2f6a873891024c062454fadaef4137573bcd0c9bd3c75089346bace3cf 980633f8-86e8-11ef-808f-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186373 https://doi.org/10.1002/adma.202103288 0 a57dd2d9-86e8-11ef-808f-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186374 Fakulteta za naravoslovje in matematiko 0 0 0
