Xue, Y.-N., Li, Y.-X., Tang, Y.-M. et al. (6 more authors) (2025) Triclinic liquid crystal of counter-rotating squashed double helices in a side-chain polymer. Journal of the American Chemical Society. ISSN 0002-7863
Abstract
A polysiloxane with tris-alkoxy-ended rod-like mesogenic side groups forms an unusually low-symmetry antiferrochiral liquid crystal, space group P1̅, consisting of distorted left- and right-handed double-helices containing alternating splay and twist sections. The unit cell contains two double-helical columns. On faster cooling, a closely related metastable orthorhombic structure is formed, symmetry Fddd, with 8 double helices per cell.
