Journal ArticleDOI
Bent-core liquid crystals forming two- and three-dimensional modulated structures.
Jadwiga Szydłowska,Jozef Mieczkowski,Joanna Matraszek,Duncan W. Bruce,Ewa Gorecka,Damian Pociecha,Daniel Guillon +6 more
TL;DR: Two columnar phases of bent-core molecules have been observed, with a two-dimensional (2D) structure modulated in the plane perpendicular to the direction of the spontaneous polarization vector, with evidence for a 3D structure in which the density modulations along and parallel to the spontaneous polarized vector co-exists.
Journal ArticleDOI
Axially polar columnar phase made of polycatenar bent-shaped molecules.
Ewa Gorecka,Damian Pociecha,Jozef Mieczkowski,Joanna Matraszek,Daniel Guillon,Bertrand Donnio +5 more
TL;DR: The polycatenar bent-shaped molecules are able to form columnar phases with column stratum built of few molecules, arranged in coplanar or conelike geometry.
Journal ArticleDOI
Liquid-Crystalline Phases Made of Gold Nanoparticles†
Michał Wójcik,Wiktor Lewandowski,Joanna Matraszek,Jozef Mieczkowski,Jolanta Borysiuk,Damian Pociecha,Ewa Gorecka +6 more
TL;DR: Spontaneous formation of smectic and columnar structures was observed when spherical gold nanoparticles were functionalized with mesogenic thiols.
Journal ArticleDOI
Nematic phase formed by banana-shaped molecules
TL;DR: In this article, the synthesis and properties of homologous series of derivatives of resorcinol and 2,6-disubstituted pyridine are presented.
Journal ArticleDOI
Polar order in columnar phase made of polycatenar bent-core molecules.
Ewa Gorecka,Damian Pociecha,Joanna Matraszek,Jozef Mieczkowski,Yoshio Shimbo,Yoichi Takanishi,Hideo Takezoe +6 more
TL;DR: The nature of the Colh and Colh PA phase transition changes from first order for short homologues to continuous for the longest one, due to decreasing intercolumnar interactions due to broadening of the columnar scaffold made of partially melted terminal alkyl chains.
