Superfluorinated Ionic Liquid Crystals Based on Supramolecular, Halogen-Bonded Anions

Abstract

<p>Unconventional ionic liquid crystals in which the liquid crystallinity is enabled by halogen-bonded supramolecular anions [C_nF_2n+1-I···I···I-C_nF_2n+1]^- are reported. The material system is unique in many ways, demonstrating for the first time 1)ionic, halogen-bonded liquid crystals, and 2)imidazolium-based ionic liquid crystals in which the occurrence of liquid crystallinity is not driven by the alkyl chains of the cation.</p>
